About

Jazzlore Chords

Features
Read full description

The chords every jazz musician should know, drawn and played. Most chord apps are encyclopedias โ€” thousands of chords, hundreds of variations, an entry for every alteration you'll never use. Jazzlore Chords is the opposite: a focused reference for the chords that actually appear on every page of every real book. The ones you need to recognize on sight, hear in your inner ear, and voice without thinking. Both notations, side by side. Cmaj7 and Cโ–ณ. C-7 and Cm7. We show you both because the jazz world uses both, and pretending otherwise is how students get confused at jam sessions. Audio for every voicing. Tap to hear the chord played cleanly, in a register that lets you sing the changes back. Staff notation. See the chord written out, not just labelled. Reading is part of the practice. Clean, distraction-free interface. Large, legible, dark by default. Made to sit on top of the piano while you work. No accounts, no ads, no tracking, no analytics. The app does one thing โ€” show you the chord, sound the chord, get out of the way. Part of the Jazzlore family of jazz reference apps. Free, open source, ad-free, made for musicians.
