See the Scale.
Hear the Chord.
Play the Music.
The jazz practice app that shows you exactly what to play — real-time scale notation, guide tones, lick patterns, lead sheet display, tempo trainer, all-keys cycle, and smart glasses integration. Import any song via MusicXML.
Not just chords. Understanding.
Other apps show you the chords and play a backing track. JazzVizor shows you what to play over each chord — in real-time, as notation, synchronized to the music.

"I built JazzVizor because I wanted the tool I wished I had when I started improvising. As a Big Band leader, I see musicians struggle with the same things — knowing what scale fits, hearing the voice leading, building vocabulary. This app makes that knowledge visible."Mike — Big Band Leader & Developer, Vienna
