Turn the notes you play into a Nashville Number chart
Click the notes on the fretboard and Bassboard Composer turns them into a printable
number chart. Right now, clicking a string just plays the note — start a chart to turn
your clicks into chord numbers.
How it works
Set your key, meter, and tuning at the top.
Click Start a Chart, then click fretboard notes — each one becomes a number. A note fills the rest of its bar; shift-click adds just one beat.
Fine-tune length by dragging on the beat grid; add quality (minor, 7th…), a slash note, or a measure note.
Use the ＋ on a section (or ＋ Add section at the bottom) to add sections like Verse and Chorus; click a section name to rename it.
The File menu holds Save, Load, Copy, View Chart, and Clear. Save downloads a backup file; View Chart opens a printable page.
Chart: Letters shows chord names instead of numbers. Spellings are kept simple (e.g. a flat 7 reads as B in D♭, not C♭ — no double-sharps or -flats).
