Store listing
By Brandon Sumner, from the App StoreDescription by Brandon Sumner Written by the developer, not by AppBrain. Click to read.
Every other piano chord app lights up four keys and stops. But four dots on a keyboard isn't the hard part — voicing the chord so it actually sounds good in your track is. Keytionary is built for that.
Pick any chord. Hear every way to voice it:
• Close, Open (drop-2), Drop 3, Drop 2 & 4
• Shell and rootless voicings (the jazz/neo-soul backbone)
• Wide two-hand spreads and stacked-fourths quartal voicings
• Upper-structure triads — the "triad over bass" trick
And it answers the question every app ignores: what does your left hand do? Swap the foundation under any voicing — root, root + 5th, root + 10th, octaves — and hear it change instantly.
Plus the full reference: 35 chord types, scales, diatonic and famous progressions, and a playable keyboard — all with real piano samples.
