A chord is a place
you make together.

Make room for every voice.

1. Choose one fret per sounding string. Click the same note again to mute it, or use the string's leftmost × button. Top row is the high E string; bottom row is low E.
2. Play every note in the recipe exactly once. Use exactly three strings for a triad, or four for a seventh chord.
3. The lowest sounding note must match the requested bass. A slash chord such as G/B is a G-major chord with B in the bass.
4. Keep the fretted span within the limit: highest pressed fret minus lowest pressed fret. Open strings and muted strings do not count toward that span.
5. Strum to hear your voicing, then keep it when all four checks pass. A nudge points to one cell on a closest valid voicing.

Keyboard: H prepares a nudge, then Enter selects that note. U undoes. R resets. P strums. Tab reaches every note. No timer; every study is available.

Standard tuning E2 A2 D3 G3 B3 E4. These are simplified note-placement studies, not complete fingering diagrams: a span limit does not model fingers or barre technique.
