One of the problems that every guitarist faces while learning is choosing a guitar tuning. The guitar tuning is determined by the sound of the open strings; accordingly, the transition to one or another key is accomplished by tuning the strings to the appropriate notes. Below is a list of the most widely used tunings:

. "Spanish" or standard. This tuning is considered a classic. This is where mastery of playing technique begins. Many people continue to play it after completing their training, since this system is universal. Designation - EBGDAE, according to strings (1st to 6th).

Drop D. One of the popular tunings, often used in rock music, especially by hard rock performers. Literally translated as "lowered D". The reason for this name lies in the fact that in this tuning the 6th string sounds a tone lower than in the standard tuning, that is, it corresponds to the note D (D). This type of tuning sounds best on an electric guitar.

Drop C. This guitar tuning, like the previous one, is based on the fact that the sixth string sounds a full tone lower than the first. However, in the case of Drop C, strings one through five are first tuned exactly one tone lower from standard tuning. That is, we get DAFCGC. In this tuning the guitar sounds lower and heavier. Used primarily in heavy music.

Open D. This tuning is most often used when playing slide guitar.

High and low tunings. Often musicians lower or raise the guitar tuning by a semitone, a tone, or even more. All strings can be tuned the same or differently. However (especially classic ones) when played in high formation they are at risk of being damaged.
. Instrumental scale. Implies a standard tuning for another instrument. You can tune it like a balalaika, charango, or cithara.

I would also like to mention that the guitar, unlike many musical instruments, is not tuned in fifth scale. Why, despite the fact that the fifth gives the purest and most pleasant sound, is the guitar tuned in such an incomprehensible, at first glance, way? The answer to this question is more than simple: standard guitar tuning provides the greatest simplicity and ease of play.

Where to start? Naturally, with mastering the technique of playing in the classical (Spanish) system. Only after studying musical literacy, especially chords, you can choose in which tuning it is more convenient to play this or that chord, this or that song. It is worth noting that for a beginner to play alternative system it will be much more difficult, especially if he does not know the barre technique.

If you play or plan to play in the future, it's worth special attention on the geometry of the neck, especially the height of the strings. The guitar may need to be re-tuned to avoid loose strings and rattling when played in the new tuning. Electric guitars for beginners are not designed for playing alternative tunings, and their sound, for example, in Drop C, may not please you. Be sure to take this into account when purchasing!

In this article I want to bring some clarity to guitar tunings. What are they, why were they formed this way, and how to generally tune your guitar. Firstly, a little educational information. The order is indicated by letters. Letters are notes that give open strings from the sixth (the thickest) to the first (the thinnest). Let's start with, so to speak, the standard - this standard guitar tuning.

Standard tuning E A D G B E (E)

In this tuning, the guitar is tuned in fourths, i.e. the interval between each string is a fourth. Read what it is. The exception is the second and third strings, the interval between which is a major third. They say in the jargon that the guitar is tuned in "E", i.e. these are the notes on the first and sixth strings. By tuning your guitar in this tuning, you can easily play regular full chords, major and minor. And in general, it seems to me that 90% of all songs can be played in it.

Low tuning Eb Ab Db Gb Bb Eb (E flat)

If all the strings are tuned to standard tuning and each one is lowered by a semitone, then we get low pitch E flat. The intervals between the strings are the same as in standard system Mi. What is this system used for? Mainly to make it easier for the vocalist to sing or for a lower and heavier sound (for example in heavy metal and other rock music).

Low tuning D G C F A D (D)

If in the standard tuning all the strings are lowered even lower - by 2 semitones, then we will get the D tuning. Here also the intervals are preserved. Essentially all lower tunings of this type are just standard tunings with a lower tuning. Used again for a heavier and lower sound, for example in heavy metal. The standard can be lowered further and get, for example, C (to). The meaning will be the same.

Dropped D: D A D G B E

Now this is more interesting. Take the E standard and lower the 6th string to whole tone. Now we have 2 D notes on open strings. Fifths on the sixth string are pressed not with 2 fingers, as in the standard one, but with one. This is probably the most popular tuning in alternative metal. Gives a meatier sound and expands the guitar's range. Well, convenience appears when playing fifths (power chords).

Dropped C: C G C F A D

Everything is the same as in the case of Drop D, only we take the lowered tuning of D as a basis and also lower the sixth string an additional tone. The favorite tuning of all metalcore players.

So, by equivalently lowering the strings, you can tune the guitar even higher or lower. That is, in fact, all these tunings above are variations of 2 tunings: standard and drop. They are probably the most popular among guitarists. Using just them, you can play 99% of all the songs in the world with ease. In addition to them, there are also a lot of non-standard tunings, but they are rarely used. And in general, you yourself can even come up with your own guitar tuning and figure out how to play it =)

If you have already decided to start playing the guitar, then the first thing you need to do when you pick up the instrument is to tune the guitar. About how it is carried out setting 6 string guitar and this article tells the story. Let's look at how to tune a guitar with and without a tuner. Never play an out of tune guitar - it will completely damage your hearing!

Standard guitar tuning

Tuning a guitar requires each string to sound a specific note. The set of notes of all strings is called the tuning of a guitar. Tuning a 6 string guitar can be done in different tunings, but we will focus on the most common one - classical system, which is more often called standard guitar tuning.

In short, any tuning is written as a sequence of notes of the open strings from the first to the sixth. The standard tuning is written like this:

E B G D A E

What does it mean in Russian:

Mi Si Sol Re La Mi

As you can see, the first and sixth strings sound the note Mi , but in the case of the sixth string it is Mi second octave (thick string), and the first string produces Mi fourth octave (thin). There will be more about this a little later.

Guitar tuner

In the age of technology, it would be strange if there was no gadget for tuning a guitar. But it exists and there are just a lot of options. Not only is this a very convenient thing, it is also very cheap.

This is a small clothespin that attaches to the headstock, i.e. to the place where the pegs are on the guitar. The clothespin contains a sensor that detects sound vibrations going about t strings Thanks to this, the tuner does not pick up external noise.

We will look at what these strange letters on the screen are, but for now I want to please you. The cost of this miracle on AliExpress only 3$. In music stores, such tuners are sold many times more expensive. I recommend purchasing it if necessary. It will come in handy, I use this myself. It's better to buy in this store .

Tuner for tuning a guitar on your phone

Today there is more than one online service for tuning a guitar. There are also enough programs for PC, for example the same Guitar Pro allows you to do this. But it is much more convenient to install the application on your smartphone and not depend on the Internet and/or computer.

There are tons of guitar tuning apps for smartphones. But the most complete and advanced among them all was and remains to this day the gStrings guitar tuner. I've been using it for 5 years now.

You can download it from Google Play Market ‘ A.

After all the changes made by the developers, the application has become maximally adapted to living conditions. You just need to take your phone out of your pocket, open the app and start plucking strings, not necessarily guitar strings. The application is omnivorous and is great for tuning a guitar, as well as for tuning a bass guitar, violin and any other instrument. Even the drums were once pulled up on it.

At the top of the tuner screen are consecutive notes. In the center is a tuned note, and an arrow indicates what to do with this note. If the arrow is to the left of the center of the screen, it means the note is not played. If it’s to the right, it’s overtightened.

A note is considered tuned if the arrow points to the center, i.e. on the note itself, while its color changes, in this case from gray to white. Today, all tuners have a similar intuitive interface.

As already shown above, notes are indicated by the first letters of the English alphabet. The letters go as in the English alphabet, in order, but starting with the note A:

• Do - C
• D - D
• Mi - E
• Fa - F
• Salt G
• A - A
• C - B

When talking about standard tuning, octaves were mentioned. Which octave a note belongs to is indicated in the program by a number next to the note. Under the note, its frequency is indicated in Hertz (Hz). The center of the screen shows the sound frequency in at the moment. For standard tuning this is:

• 1 string — E 4 — 329.63 Hz
• 2nd string — B 3 — 246.94 Hz
• 3rd string — G 3 — 196.00 Hz
• 4th string — D 3 — 146.83 Hz
• 5 string — A 2 —110.00Hz
• 6th string — E 2 — 82.41 Hz

Don't get confused! otherwise in best case scenario You'll break the string, or at worst, you'll damage the guitar.

Tuning a 6 string guitar by notes

Today, given that everyone has a smartphone or two in their pocket, this option for tuning a guitar can be considered outdated, but you shouldn’t write it off. One way or another, everyone who plans to continue playing the guitar should know it. You never know, suddenly the battery on your smartphone runs out)

The method is based on the fact that each subsequent string is tuned to the previous one by ear, by resonance. As we already know, the open first string produces the note Mi. If we hold down the second string at the fifth fret, we will also get the same note Mi and a resonance will arise between them, i.e. they will begin to enhance each other's sound.

This means that in order to tune the second string, it needs to sound the same as the open first string at the fifth fret. Therefore, we clamp the second string at the fifth fret, pluck the first string, and then the second, and try to determine whether the second string sounds higher or lower.

At the same time, to make it easier to determine whether the second string is understretched or overtightened, you can move from the fifth fret to other frets and look for which fret the resonance will occur on. If it occurs on higher frets (6,7,8...) then the second string should be tightened even more. If resonance occurs if you hold the second string at lower frets (1-4), then the second string is overtightened.

Guitar beats and tuning

When you come very close to the desired note and the difference between the notes is very close, so-called beats occur. Beating is the result of a slight difference between two close frequencies that are trying to resonate, but because of the slight difference, the sound is either strengthened or weakened. Graphically it looks like this:

When setting acoustic guitar, the beats are not only perceptible by ear, but also clearly felt by the body when touching the soundboard (body) of the guitar. This is especially noticeable on the upper bass strings, due to their thickness and lower sound frequency.

The closer the sounds of two notes correspond to each other (the second string on the fifth fret and the open first), the faster the beats will occur. And when the notes coincide, the beats will stop altogether. You just have to feel it and then you can adjust it without thinking.

By analogy for the other strings. The third string should sound the same as the second open string when plucked at the fourth fret. To tune the 4th, 5th and 6th strings, you should clamp them at the fifth fret and compare their sound with the sound of the previous string.

It turns out that all strings except the third are tuned according to the resonance between them at the fifth fret and the previous string, and the third string is similar, but is clamped at the fourth fret.

Sheet music for guitar tuning

In this way, you can tune the guitar in reverse order or starting from any string, but there is one thing in this method weak point. Initially, one of the strings must be tuned from outside. The tuning fork was invented for these purposes. A standard tuning fork produces an A note with a frequency of 440 Hz. Those. This is the first string on the fifth fret.

Especially for you, a 20-second file with the note A (440Hz) produced by a standard tuning fork was created in the Audacity audio editor. Well, and at the same time 20 seconds of the sound of the first string.

Download or listen online sheet music for guitar tuning:

You can create the sound of any note yourself in Audacity. How to do this, read the article:

Another instrument, such as a piano or a second guitar, can serve as a reference. But it’s better to memorize some melody for yourself, preferably using all the strings separately, by playing which you could accurately determine whether the instrument is out of tune and which strings should be tuned.

For me personally, such a melody is the introduction of Viktor Tsoi’s song “Aluminum Cucumbers.” If you develop auditory memory and remember the sound of notes, then you can tune a guitar without a tuning fork, and even more so without tuners, without any problems. It just takes practice and regular play.

And finally, a video showing another guitar tuning option:

The article was written exclusively for the site

There are a lot of bands in the world that play in a variety of tunings. It seems that one can get confused in such diversity. But if you look closely, it turns out that almost all tunings belong to one of several common types, which I will now describe.

In the pictures below I have depicted the “formulas” of these types. It’s not very visual, but it’s beautiful and New Year’s-like. The numbers indicate the interval between adjacent strings. For example, in standard tuning, the second string is 5 semitones lower than the first, the third is 4 semitones lower than the second, and so on.

This sequence is familiar to anyone who has tuned a guitar “by itself”:

Any tuning with the same sequence of intervals (5-5-5-4-5, if you count from bottom to top) is also a standard tuning, only lowered (or higher). The same chord and scale fingerings will work in it. Any part written in E standard can be played in D standard tuning, it will simply sound a tone lower. The very essence of the tuning - the intervals between adjacent strings - remains the same.

From a "just play" point of view EADGBE- this is the same as DGCFAD. I want to play something from Death, and a guitar in standard tuning is not a problem, we look for taboos and play. It will just sound a tone higher. Because the TYPE of structure is the same. Other options:
- raise the original by a tone in the audio editor and play along with it.
- lower the guitar with a pitch shifter in real time and play to the unaltered original.
- record the minus in standard tuning and play to it.

And if the intervals are different, then we are talking about a different TYPE of structure. If you want to play something from Killswitch Engage, you need to understand what type of system it is. And it turns out that they CGCFAD- this is the same as DADGBE, but a tone lower. So all you have to do is switch to good old DropD.

The easiest way to determine the type of tuning is to read this post, and then enter the tuning in guitarpro and raise and lower the whole thing until something familiar or as close as possible to the standard appears:

I have provided examples for each type of structure. If I write only the name of the group, it means that this structure is the main one for it. It's the same with albums. If a song is listed, the band made one or more songs in that tuning, but used others more often.

Then I indicate the pros and cons of the tuning and which version is closest to the standard tuning (“for testing”). If “for trial” is not indicated, it means that the tuning requires a custom set of strings in any of its variants.

Standard tuning

Standard tuning is a tuning in which all intervals between the strings are 5 semitones, and only between the 2nd and 3rd strings there are 4 semitones. The most standard version (which is simply called the standard tuning) is the one that begins and ends with E - EADGBE. All other options are named by open note, which is obtained on the first or sixth string: for example, D standard.

E standard	EADGBE	The vast majority of all groups in the world. True, it is not so easy to find a large/famous group that would play ONLY in Mi standard. All the heroes of rock are the Beatles, Rolling Stones, Pink Floyd and so on, at least sometimes they turned to other systems. Even AC/DC has several songs in Eb standard. Perhaps the only classic of rock that can be cited is Queen, and even then I’m not entirely sure ( update: Queen also disappears: they have Headlong in DropD). It’s even more difficult with metalheads. All major bands either originally played in lowered tunings, or switched to them over time. Well, again, Burzum and Darkthrone probably have everything in standard order.
Eb standard	EbAbDbGbBbEb	Jimi Hendrix, Stevie Ray Vaughan, Black Sabbath, Motorhead, Guns"n"Roses
D standard	DGCFAD	Death, Children Of Bodom, Nightwish, Gojira, Ghost, Nirvana in "Lithium", Metallica in "Sad But True"
C# standard	C#BEG#	Black Sabbath on the album "Master Of Reality", My Dying Bride, Limp Bizkit Dying Fetus
C standard	CFBbEbGC	Dethklok, High on Fire, In Flames, Queens of the Stone Age, Kyuss
B standard	BEADF	Amon Amarth, Crowbar, Soilwork, Carcass, Type O Negative, Sepultura in "Roots"
Bb standard	BbEbAbDbFBb	Cannibal Corpse in "Blowtorch Slaughter"
A standard	ADGCEA	KYPCK

Some groups (Placebo, Vektor), on the contrary, raise the standard scale by a semitone. Johnny Marr of the Smiths used a tuning a step higher than standard on some songs ("This Charming Man").

+ Standard tuning is the ideal compromise between range and ease of playing chords and melodies. Friendly with many tonalities. This is done especially clearly after you try several alternative tunings: many of them are better than the standard one in one of the parameters, but they are necessarily worse in another or several. The standard has become a standard for a reason - it is the most practical and universal.
– Sometimes you want something different)

Drop tunings

Drop tuning is a standard tuning with the sixth string lowered a tone.
They are named after the open note produced on the sixth string. For example, DropD is DADGBE.

+ Range extension down, power chords with one finger, and their extensions up (like 447454), the first five strings are tuned as in the standard - play solos as much as you want
– Slightly less versatility than standard tuning. The increased “gap” between the 5th and 6th strings somewhat limits play in the lower range.
To try: DropD (DADGBE)

Open formations

They are obtained when all the strings are tuned to the notes of a chord. Usually major or minor. They are called by the name of the chord. There is no clear connection between the name of the system and the system. For example, " open A major" is any tuning where there are open strings A, C# and E (and no others). It could be EEAAC And EAC#AC or even reduced AEAEAC#.

The most common options:

5-7-5-4-3

Open G	DGDGBD	Rolling Stones in "Brown Sugar" and "Start Me Up", Alter Bridge in "Watch Over You"
Open A:	EEAAC	Led Zeppelin in "In My Time of Dying", White Stripes in "Seven Nation Army"
Open F:	CFCFAC	Led Zeppelin in "When the Levee Breaks"

7-5-4-3-5

Open D	DADF#AD	Joni Mitchell in Big Yellow Taxi
Open E	EBEG#BE	Derek Trucks

7-5-7-5-4

>

Open C	CGCGCE	Devin Townsend
Open B	BF#BF #BD #

To try: Open G, Open D, Open C

+ Suitable for playing with a slide
– They are friendly to one or two keys, can be very inconvenient in others, and are not always friendly with scale-like passages.

Modal scales

That's what they call it open formations, based on a chord that is not major or minor. Typically this is a sus2 or sus4 chord.

The most famous of them is the “Celtic tuning” (opened by Dsus4):

Standard option - DADGAD(Led Zeppelin in "Kashmir", Staind in "Epiphany"). Lowered versions of this tuning were used by Mark Tremonti in Creed and Alter Bridge, Russian Circles and Sevendust.

Drone formations

Tunings where all or almost all the strings are tuned to the same note (not necessarily the same octave).

DDDDDD- The Velvet Underground in "Venus In Furs"
BDDDDD- Goo Goo Dolls in "Iris"

+ Very different
– Very specific

"Seven-string without a sixth"

This is a standard tuning in which the sixth string is lowered not by a tone, as in drop tunings, but by 5 semitones. It turns out like a seven-string with a missing sixth string. And the fingering, which usually gives a fifth on the 5th and 6th strings, now gives an octave.

+ Fingerings can be moved anywhere on the fingerboard without having to adjust them. Complete symmetry.
– You'll have to forget about open chords and barre chords.
To try: EADGCF or D #BE (if you don’t want to tune the first and second strings higher)

Fifth scale (all Fifths)

Each next string is a fifth (7 semitones) higher than the previous one.

One of the main versions is CGDAEB. The lower C then turns out not too low for acoustics, but the upper B turns out to be very high - a fifth higher than the standard upper E. On a guitar with a standard scale and ordinary strings, this B is unattainable: the string will simply break before reaching it.
This guy from YouTube very carefully used thin string to get the top C.
A this one put it on classical guitar instead of the first string, fishing line with a cross section of 0.5 mm, in combination with five nylon strings from the regular kit.

The other extreme is to start with the standard high E and work fifths down from there. It will work out FCGDAE, the first string is as in standard tuning, and the sixth is almost an octave lower than the sixth in standard tuning. This is too low to produce clean notes on a standard scale guitar with this string. You will need a baritone or multi-scale guitar.

+ Complete symmetry, as in the fourth tuning. Huge range (almost an octave wider than standard tuning).
– You need a custom set of strings and a willingness to make compromises (or order an instrument with a multi-scale). You'll have to forget about small intervals and chords in which the notes are close to each other. Playing scales and melodies will require increased stretching.

By the way, a mandolin is tuned to fifth tuning ( GDAE), and that's it bowed instruments, except double bass: for example, violin in GDAE, and the cello in СGDA. In addition, there are four-string tenor guitars which have 4 strings and are tuned in fifth tuning CGDA.

"New Standard Tuning"

A tuning invented by Robert Fripp to solve the problem of the fifth tuning. He replaced the top fifth with a minor third, and it turned out CGDAEG. Upper Sol is also high, but already achievable. Can be used standard strings 9 or 10 gauge. But it’s better to assemble a custom kit.

"Nashville tuning"

-8 in the formula means that the 2nd string is tuned not higher than the third, but 8 semitones LOWER. “Nashville tuning” usually works out like this: we take a set of strings for a 12-string and put only the “thin” half of it on the 6-string, tuning it in the same way as on a 12-string. Now the first and second strings are tuned the same as in standard tuning, and all the others are tuned an octave higher. The result is a “ringing” tuning with a reduced range, in which some notes in the chords will be duplicated. This tuning is suitable for overdubs and any additional parts. For example, you can record the same chord part on a 6-string in standard tuning and the same chord in Nashville tuning. In essence, it turned out to be a 12-string, but the only difference is that this is not one performance, but two slightly different ones, which will give more volume, besides, these are two separate tracks and can be panned in different directions.

Double-drop tunings

They are obtained when in standard tuning they lower not only the sixth, but also the first string by a tone.

Double Drop D	DADGBD	Neil Young on "Cortez The Killer", Led Zeppelin on "Going To California"
Double Drop B	BF#BEG	Isis

To try: DADGBD. It's funny that this system is “one step away” from each of the three above - DropD (DADGBE), Open G (DGDGBD) and DADGAD.

Now about the seven-string guitar.

The standard seven-string tuning is a six-string E standard plus a 7th string in B.

Seven string B standard	BEADGBE	Dream Theater in "Caught In A Web", Steve Vai in "Riddle", Joe Satriani in "Mind Storm", Fallujah
Seven string Bb standard	BbEbAbDbGbBbEb	Morbid Angel, early Meshuggah, Nevermore
Seven string A standard	ADGCFA	Fear Factory, Korn
Seven string Ab standard	AbDbGbBEAbDb	Deftones on "Hexagram"

Seven-string Drop tuning is a seven-string standard in which the seventh string is lowered a tone.

Seven-string DropA	AEADGBE	Suicide Silence, Whitechapel, later Scar Symmetry. Jazz guitarist George Van Eps, who played a seven-string electric guitar back in the 60s, also used this tuning.
Seven-string DropAb	AbEbAbDbGbBbEb	Periphery on seven-string songs
Seven-string DropG	GDGCFAD	Vildhjarta, Emmure
Seven-string DropF#	F#BEG#	Rivers Of Nihil, Deftones on Saturday Night Wrist album
Seven-string DropD	DADGCEA	Black Tongue

Some people take the six-string drop tuning and add a seventh string from the bottom. It can be a third lower:

Six-string DropD + low B	BDADGBE	Animals As Leaders in "Cafo"
Six-string Drop C# + low A#	A

And he even posted it, albeit in English.
In general, today I decided to touch upon this topic again and consider the most common of them.

It wouldn’t hurt to remind you of simple things. If you decide to tune lower, then it is better to take a thicker one, otherwise in some Dropped the usual nine will just dangle and ring on the frets. If you decide to make the tuning of your guitar higher, then in this case you can take thinner strings, because Large gauge strings, in this case, can be very tight. Well, no one has canceled the excess load on the bar either.

Also, if there is a radical change in the system, be prepared to do it again, although you may not have to do this.

So, let's go.

Standard tuning: E-A-D-g-b-e

In standard guitar tuning All the intervals between the strings are perfect fourths (five semitones), with the exception of the interval between the third string (g) and the second string (b), which is a major third (four semitones).

Down a semitone: Eb-Ab-Db-gb-bb-eb

This guitar tuning is also called "Eb" - based on the note to which the thickest string is tuned. Tuning the guitar is exactly the same as in standard tuning. The sound intervals between the strings remain exactly the same, but each string is tuned exactly one semitone lower than the standard tuning. Eb tuning can be used for many reasons, such as making the strings softer and bending easier, or to better suit a singer's vocal range. There can be many reasons. This tuning was used by Jimi Hendrix and Stevie Ray Vaughan.

Down a whole tone: D-G-C-f-a-d

This tuning is also called “Tuning D” - based on the note to which the thickest string is tuned. Everything is the same as in the previous case, except that each string is tuned a tone lower than the standard tuning. This tuning is used for the same reasons as "E?", it causes the strings to sag even more and makes bending even easier. At this point I would think about using thicker gauge strings.
If this is not enough for you, then you can continue further. Those. lower or lower each string at an equal interval relative to the standard tuning. The algorithm is simple, the main thing is to choose the appropriate size strings.

Drop-D: D-A-d-g-b-e

Drop-D is probably one of the most popular tunings in hard rock, alternative and other motherfuckers. By the way, folk guitarists do not disdain them either. Although they are generally big fans of alternative and non-standard guitar tunings.
By lowering the low E string one step to D, we can make power chords easier to play. Now they can be played with one finger, simply by plucking three thick strings, the 4th, 5th and 6th, respectively. Drop-D tuning gives a meatier sound and extends the overall range of the guitar towards the bottom compared to standard tuning.
By the way, this system does not require a large and lengthy restructuring, which allows you to change the system right on the fly, with the proper skill, of course.
To facilitate this procedure, a special device was even invented and made - the D Tuner, which will allow you to literally rebuild the sixth string in a second.

Double Drop-D: D-A-d-g-b-d

Double drop D is Neil Young's favorite tuning. It is identical to the regular Drop-D, except that the high e is also lowered one tone from the standard tuning - to d. With this setup, it turns out that the 4th high strings form a G major chord, and this can be convenient when playing with a slide. This tuning is also quite quick and easy to get from the standard one.

Drop-C: C-G-c-f-a-d

This tuning will help make your guitar sound lower and meatier when overdriven. This tuning is achieved by first tuning the guitar a tone lower than standard, and then lowering the 6th string another tone.
Quite low, don't you think? With this tuning, thicker strings are clearly needed. Thin ones will obviously hang around like snot.
In general, the technique is simple. We already understand what Drop is. But whether to lower it by one tone, 2 or more - that’s up to you. Everything will depend on the gauge of the strings and your desire.

Tuning D5: D-A-d-d-d-d

This system is classified as open formations, because If all the strings are open, the chord D5 sounds. This tuning is quite often used when playing slide. To get this tuning you need to lower the 3rd string by 5 semitones, raise the 2nd string by 3 semitones and lower the 1st string by a tone.
There are variations of this tuning in which the 3rd string is raised to A instead of lowered to D. This gives two fifths of a step in different octaves, which gives the sound some depth.

Ostrich formation: D-D-d-d-d-d

In this tuning, all strings are tuned to the same note. Lou Reed is said to have invented this tuning while he was with the Velvet Underground. Important note: With this tuning, you will definitely need to build your own set of strings.

I guess I'll stop for today. This, of course, is all alternative and non-standard guitar tunings are not exhausted.
I think I’ll throw in a dozen more soon.
