Sheet Letters

Turns sheet music into note letters you can read at a glance, measure by measure, with chord names, the key and the lyrics underneath.

What it does

Open a MusicXML or MIDI file and every note becomes its letter: C, D, E, F♯ and so on, laid out measure by measure like lines of music, one row per staff. Lyrics sit under their notes, chords get their names, and held notes are marked so you know to keep holding.

What you can do with it

Transpose the whole song up or down, colour the notes, show octave numbers, switch to a compact or plain-text view, and copy the result to paste anywhere. A PDF or photo of sheet music needs one step first: a free recognition program turns it into MusicXML, and the app walks you through it.
