Turn Jazz Piano Voicings Into Muscle Memory
A MIDI-first practice system for building real jazz piano fluency through hands-on playing, not memorization or chord trivia.
Not a Chord App
Most apps test your knowledge of chords.
This one trains your ability to play them instantly at the keyboard.
No tapping. No quizzes. No memorization loops.
Just real playing that builds real fluency.
See It
Understand real jazz voicings in context, not isolated shapes — usable harmony
Play It
Use your MIDI keyboard
or on-screen keys to perform in real time
Get Feedback
Instant response on accuracy and voice leading, so you know what actually works
Lock It In
Spaced repetition turns practice into reflex
until voicings become automatic
Why this actually works
Play Voicings on a Real Keyboard
Connect your MIDI keyboard and practice voicings the way they’re actually used—under your fingers, in real time.
Build instinctive control at the keyboard through real-time playing.
Your Practice, Your Curriculum
Custom Practice lets you design your own jazz drills. Choose chord types, keys, and ordering to target exactly what you need, then save and repeat practice presets. This turns the app into your personal jazz curriculum — built around how you actually practice and improve.
Practice That Adapts to You
The system adapts to your playing. Hard voicings repeat more often. Mastered voicings fade out. Every session is focused, efficient, so voicings become automatic under your fingers, not repetition for its own sake.
Keep Improving Anywhere
No MIDI keyboard available? You can still reinforce voicings on the go with on-screen practice—but real fluency is built with a keyboard.
