⏱ Time per chord

Dm9

ii — supertonic (minor chord)

LEFT

RIGHT

tap a key to hear one note

Major: ii = m9 · V = 9 (or 13) · I = maj9 (or maj13) | minor: ii = m7♭5 · V = 7♭9 · i = m9.
✨ 13th off (default) keeps every chord on the 9th — the 5th stays in the voicing. 13th on puts the 13th in place of the 5th on the V and the I (and the ♭13 on the minor V), the same rule as the Finger Position app.
The left hand always plays root + fifth low on the keyboard; the right hand keeps one hand position, anchored on the key's tonic.
Shortcuts: Space = done · H = show voicing.
⏱ Time per chord: no limit, or 10/20/30s. When the clock runs out the voicing appears and the chord plays, then it waits 5 seconds — or until you press Done — before moving on. Showing the voicing by hand stops the clock.
