The chord chart editor

A chart is split into named sections: intro, verse, chorus, bridge, pre-chorus, solo, outro. Each carries its own repeat count, shown as “×2” next to its title, which saves copying the same progression eight times. Sections can be reordered by dragging, and duplicated in one click when a chorus returns with a variation.

Each section has its own time signature. A 4/4 bar gives four beats, a 3/4 bar gives three. The signature is set per section, so a song whose bridge turns into a waltz needs no starting over.

Every cell takes an adjustable duration, from a quarter of a beat to four full beats, in quarter steps. Three buttons are enough: the left arrow absorbs the previous cell, the right arrow absorbs the next, and the divide symbol splits the cell in two. That is how you write two chords on one beat, or one chord held across a whole bar.

Tab moves from one cell to the next, then down to the following bar. At the end of the last bar it creates a new one and steps into it: a whole chart can be typed without ever leaving the keyboard or clicking “add a bar”.

You can type “Am” or “Lam”, “Fa#m7” or “F#m7”: French entry is recognised and converted. Display then follows each reader's preference, set in their profile — two musicians can read the same chart in two different notations.

Rather than typing, you can play. The mic button listens, recognises the chord, writes it into the target cell and moves to the next. Silence acts as confirmation: play the chord, mute the strings, it is written. That is what makes it possible to write the same chord twice in a row, which a held chord could not distinguish.

When you know the shape but not the name, the chord finder does the opposite of a dictionary: click the frets on the neck or the piano keys, and matching chords appear, ranked by closeness. One click inserts them into the cell.

A chord whose suggested shape does not suit can be redrawn for the chart: open strings, muted strings, barre, starting fret. The custom shape travels with the chart, including in print and for anyone reading it.

Entering the title and artist looks up the tempo automatically and brings in the album artwork. The key is derived from the chart's own chords as soon as there are two: it therefore describes what is written, capo included, not the original recording. Both stay editable by hand, and a value you enter is never overwritten.
