Click a chord to add it to the end. Drag chords or use the arrows to reorder, and tap the length to change how long each one lasts. Changes come in the next time round. The fretboard follows the music: it lights up each chord’s notes as the chord arrives, with a scale that fits it, and rings the next chord’s notes on the last beat. Click a chord to look at it while stopped. Use the mixer to balance the band, or turn the guitar down to play the chords yourself.

Rhythm
No rhythm notation needed: the space between notes is the rhythm. Each beat is the same width, so a note twice as far from the next one lasts twice as long. Notes ring until the next note on the same string.

Guitar Tuner

Tap a string to hear it, or start the tuner and play

The tuner listens through your microphone, works out which string you're playing and goes green when you're within 3 cents. Nothing is recorded or sent anywhere. The tuner is also in the menu at the top of every page.

How to name a chord

Tap the fret you're holding on each string. Tap a string's fret again to mute it. The chord name appears straight away with each note and its interval, so you can see why it's called what it is. If a shape could have more than one name, the most likely one is shown first with the others underneath.

Slash chords like C/E mean a C chord with E as the lowest note. They're common in songs, and the finder spots them for you.

How to find the key of a song

Add the chords from the song in any order. The finder checks them against every major and minor key and shows the best matches, with the chords of each key numbered so you can see how the song fits together.

It also tells you which scales to solo with. Open the key in the Fretboard Navigator to see those scales on the neck, or the Backing Track Creator to jam over the same chords.

When a chord doesn't fit

Plenty of songs borrow a chord from outside the key, like a major IV in a minor key or a flat VII in a major key. If one chord doesn't fit, the key with the most matches is usually still right.

Frequently asked questions

How do I find out what chord I am playing?

Tap the fret you are holding on each string and mute the strings you are not playing. The finder names the chord and shows each note and interval.

How do I work out the key of a song?

Add the song's chords. The key whose chords match the most is usually the one, and the first or last chord of the song is often the key's home chord.

What is a slash chord?

A chord with a different note in the bass, written chord/bass note. C/G is a C major chord with G as the lowest note.

Why are there two possible keys?

Every major key shares its chords with a relative minor key, like C major and A minor. Which one it is depends on which chord feels like home.

What scale should I solo with?

Start with the major or minor pentatonic of the key, then try the full major or natural minor scale. The finder suggests both for each key.
