Free online guitar tools

Everything here runs in your browser. Nothing to install, no account to create, no ads. These tools were built by a guitar teacher in Paris for his own adult students, then put online as they were.

Tuning

Nine tuners and one guide, all listening through your microphone. They are the same engine, each opened on a different tuning, and they all show you a reading in cents rather than a green light. A number you can see tells you which way a string is pulling, and by how much.

Online guitar tuner

A chromatic tuner that listens through your microphone and shows how far off you are, in cents.

Twelve tuning presets, from standard to DADGAD, plus bass and ukulele. Free, in your browser, no account.

Bass tuner

The same tuner, opened on bass, with presets for four strings (E A D G) and five (B E A D G).

It widens its analysis window for the low strings, where a bass needs more time to be read. Electric or acoustic.

Ukulele tuner

The same tuner, opened on G C E A, the tuning of soprano, concert and tenor ukuleles.

Low G and baritone D G B E sit in the preset menu. Chromatic, so it names any note you give it.

Open D tuner

Opens on Open D, D A D F# A D, where the six open strings already sound a D major chord.

Three strings come down and none goes up. The page covers one finger chords across the neck, and slide basics.

Drop D tuner

Opens on Drop D, D A D G B E. Only the thickest string moves, a whole step from E down to D.

The bottom three strings become a power chord with nothing held down. Double Drop D and Drop C are explained too.

Drop C tuner

Opens on Drop C, C G C F A D, a whole step below Drop D on every string. The low C needs heavier strings, and the page says which.

The tuner widens its analysis for that low C, which a standard window reads late. Drop C sharp is covered through the chromatic reading.

Open G tuner

Opens on Open G, D G D G B D, where the open strings sound a G major chord and one finger across the neck gives the next chord.

Three strings come down, nothing goes up. The page covers one finger chords, slide basics, and whether to keep or drop the sixth string.

DADGAD tuner

Opens on D A D G A D, one string away from Open D: the open strings sound a Dsus4, neither major nor minor.

Davy Graham, the Celtic folk sound, chords with one or two fingers, and DADGAD against Open D. Reference tones for each string.

Half step down tuner (Eb)

Opens on Eb Ab Db Gb Bb Eb, standard tuning with every string lowered by one semitone.

Your shapes and your tabs all still work, one fret lower. The page says why so many records are played there.

How to tune a guitar

The written guide to standard tuning, E A D G B E: with an online tuner, with a clip-on, or by ear with the 5th fret method.

It also covers what changes between an acoustic and an electric, why a guitar drifts out of tune, and where alternate tunings fit.

Guitar string notes and names

E A D G B E, from the thickest string to the thinnest, with the frequency of each one and the way to remember the order.

Every note on each string up to the twelfth fret, as a table, plus bass, ukulele and 7 string guitar.

Tempo and rhythm

Find the tempo of a record, hold one yourself, then put a pattern on it. Those are three different jobs, so they have three pages. The metronome goes past a plain click: subdivisions between the beats, an accent on any beat of the bar, mute modes that drop a share of the clicks at random, and bar by bar programs that chain tempo, time signature and subdivision on their own, which is how a tempo ramp becomes a few lines of text.

Chords and fretboard

Some of these run in the page and some are written pages you read, but they all come back to the same question: which notes sit under your fingers, and what chord they add up to.

Each card says what its page does, and also what it does not do, because that is usually the faster way to find the right one.

Interactive fretboard

Every note from the nut to the twelfth fret, and tapping a fret plays it. Show the names or hide them, as sharps or as flats.

Change the tuning, light up a chord or a scale across the whole neck, then turn a quiz on and answer on the board.

Guitar chord chart

The 24 shapes that cover most of the pop, rock and folk repertoire, each one drawn with its fingering, its muted strings and its barres.

Every diagram is on the page. Below them sits the generator that laid them out, so you can change the size, the colors or the list and print it.

Chord finder

Give it a shape, as a string code or by clicking the grid, and it draws that chord as a clean diagram. There is no library to browse here.

Barres, finger numbers, colors, a left handed mode, and any window on the neck. Download the result as a PNG or an SVG.

What chord is this?

Give it an audio file, a direct audio link or the sound of a browser tab, and it names the chord that is sounding. There is no microphone mode.

It timestamps every change, so you come away with a chord chart rather than a guess. Nothing is uploaded, and nothing leaves your browser.

Basic guitar chords

The open chords a beginner learns first, E, A, D, G, C, E minor, A minor and D minor, written out string by string and finger by finger.

Each shape comes with the fault it usually produces, the change it leads into, and the place it takes in the order you learn them.

Capo chart

Which chord your shape actually sounds at each capo fret, because once the capo is on, the shape you play and the chord you hear stop sharing a name.

It reads the other way too: pick the key you need, find the fret that gets you there, and see the shapes that come with it.

The F chord

The chord that stops most beginners, in the order to learn it: the three finger shape, the half barre, then the full barre at the first fret.

Why it is hard, four fixes that make the barre ring, and the C to F change written out. The easy xx3210 shape is named for what it is, an Fmaj7.

Barre chords

Two movable shapes, E and A, major and minor, and with them every chord on the neck. A chart gives the fret of each one by note.

Pressure, thumb and angle, the three things that make a barre ring, plus the honest easier versions of B minor while the shape settles.

Power chords

Root and fifth, two or three fingers, one shape that slides anywhere. A chart gives every power chord by note on the sixth and fifth strings.

Palm muting, the right hand, and Drop D, where the whole shape becomes one finger laid flat.

Chord progressions

A generator that builds a progression in any key and plays it back with piano, bass and drums, then exports it as MIDI.

Below it, a chart of the progressions behind most songs in all twelve keys, the minor keys, and the 12 bar blues written out.

Chords in every key

The seven chords of each of the twelve major keys, with their function, the four that songs use most, and the relative minor.

One anchor per key, so the key of G is one click away. Everything is calculated, with the spelling each key really uses.

The CAGED system

Five open shapes, C A G E D, become five positions of the same chord up the neck, each drawn as a diagram.

Where the root sits in each shape, a chart of every major chord in all five, and why the E and A shapes come first.

How to read chord diagrams

Strings, frets, the nut, dots, X and O, barres and higher positions, then chord charts in songs and string codes like x32010.

Five diagrams to read right now, drawn by the site, with their fingerings written out.

Write and print

Reading somebody else's tablature, writing your own, and the blank sheets for the times a printed page beats a screen. The two generators redraw their preview as you change a setting, and both end on a printer or in a PDF.

Songs, and how long it takes

Most lists call a song easy and stop there, which is how a beginner ends up with a part that was never going to work yet. This one gives every song a level instead, L1 or L2 on the scale used in lessons, and says what the arrangement actually asks of your hands. The list is drawn from our catalog, and a song nobody has placed on the scale is left off rather than given a level it has not earned. The same scale answers the other question a beginner asks, the one about time.

Who made this

Guitar Social Club is the work of Yohann Abbou, a guitar teacher in Paris. He teaches adults, and that shapes everything here: people with jobs, an hour of practice a week if the week is kind, and a short list of songs they actually want to play.

These tools come out of his lessons, which is why none of them asks you to sign up before it works, and why they show you a reading rather than a verdict.

About Yohann Abbou

Thirty five years of teaching, the eight level scale, and where every figure on this site comes from.

The longer version, with the App Store rating, the size of the video catalog, the research with the CNRS, and why none of the tools asks for an account.
