Writing the chords

The chords are the one thing you must type. Write chord symbols separated by spaces, in the box labelled Chord progression. How the lines you type map to time is covered next, in Lines are bars; this part is just the notation for a single chord.

The notation covers most common chords:

• Triads — C, Am, F, G. A bare letter is major; add m for minor.
• Sevenths and extensions — G7, Cmaj7, Am7, D9, Em11. Write the quality straight after the root.
• Suspended and altered — Csus2, Dsus4, Bdim, Faug.
• Slash bass — put a bass note after a slash: D/E, Bm/F#, Gmaj7/B. The chord stays the same; the note after the slash is played in the bass.
• Rests — N.C. ("no chord") leaves a silent gap. You can still give it a bass note: N.C./B plays just that bass tone.

The sharp or flat goes right after the note letter (F#, Bb). A quality the app doesn't know written on a real note — a stray suffix, say — falls back to a plain major triad on that root rather than failing; but a symbol it can't read as a chord at all is flagged as unrecognised in the live preview, and the render stays disabled until you fix it.

Example. Am is A minor, Cmaj7 is a C major-seventh, and Am F C G/B is a four-chord run that puts B in the bass under the final G. A bare G and Gmaj are the same chord; G7 adds the flat seventh.
