About
JazzSession started as a personal tool — a place to log sessions, reference scales quickly, and stop fiddling with spreadsheets mid-practice. It grew into something worth sharing.
Great jazz practice isn't about quantity — it's about intention. Knowing what you worked on, spotting what you're avoiding, and showing up consistently over months and years. JazzSession tries to make that reflection effortless.
No subscriptions, no bloat, no ads. Just a focused set of tools that get out of the way and let you focus on the music.

JazzSession is a personal passion project. I built it because I wanted a practice log that actually understood jazz — scales by name, standards with chord charts, a metronome that wouldn't drift. If you're using it, I hope it's helping you play better.
