## 408Jazz Description
408Jazz — Jazz Piano by Ear
Learn jazz piano the way jazz musicians actually learn — by ear, not by reading.
408Jazz is your pocket guide to the sounds, colors, and vocabulary of jazz. Whether you're sitting down at the keys for the first time or looking to deepen your understanding of harmony, 408Jazz gives you the tools to hear what you're playing and understand why it works.
Explore Jazz Harmony
Dive into the chord library and hear every essential jazz voicing — from major 7ths and dominant 9ths to altered chords and beyond. See how each chord is built, hear how it sounds, and explore where it lives in a progression.
Understand Modes & Colors
The Modal Colour Guide brings modes to life across all 12 keys. Hear the emotional quality of Dorian, the tension of Lydian Dominant, or the sophistication of Altered — and learn to recognize them by sound, not just by formula.
Train Your Ear
Put your listening to the test with the Ear Training module. Identify chords and intervals by ear and build the internal musical vocabulary that separates great jazz musicians from good ones.
Track Your Practice
Log your sessions, track topics, and watch your progress grow over time. Share your practice log or reset and start fresh whenever you're ready.
Built for Jazz, Designed for Mobile
Dark mode, smooth navigation, and an interface that gets out of your way — so you can focus on the music.
408Jazz. Learn the language. Play the music.
