Type the song once, chart it forever — transpose to any singer's key in one tap, flip between letter chords and Nashville numbers, and print a chart the whole room can read.
Put each chord in brackets right where it lands: [C]Amazing [F]grace. Section names in brackets on their own line: [VERSE 1], [CHORUS]. Slash chords ([C/E]) and qualities ([Am7], [Fsus4], [Bb]) all work.
