ZZZ FretHarmony

Learn a chord where you play it: on the neck.

A guitar practice app that draws the relationship between chords and scales on the neck itself.

■ The whole neck, drawn Chord tones, scale tones, extensions and avoid notes, muted and open strings — each told apart by colour and shape. Switch to degrees and a shape becomes the same shape in every key.

■ Every fingering a chord has From the chord book anyone learns first to every position on every run of adjacent strings. Choose by which string the root is on, and narrow it down by arrangement: close, drop 2, drop 3, shell, power chord.

■ Progressions written in degrees Diatonic or not, a progression is built from degrees. Change the key and the whole thing transposes; change key part way through and it modulates. Start from a preset or from nothing at all.

■ Arpeggios with a rhythm of their own Not only up and down: three-finger and Travis-style patterns that have a rhythm in them, and a different pattern for each bar if you want one.

■ Eight recorded instruments Electric, acoustic and nylon-string guitar, piano, organ, harp, cello and flute — each note pitch-corrected one at a time. A synthesised string is there too.

■ More than thirty scales Every mode of the major and minor scales, pentatonics, both blues scales, bebop, whole tone, diminished, altered, Hungarian minor, and the Japanese scales: hirajoshi, in sen, yo and ryukyu.

■ It all stays on your device No account, no sign-in. Settings and saved progressions live on the device only, and nothing about what you play is sent anywhere.

On a tablet the neck stays visible while you work; on a phone it stays pinned while the controls scroll under it.
