Jazz Guitar Lab

Jazz Guitar Lab turns jazz harmony from something you read about into something you play. Most theory apps hand you diagrams. This one puts a real fretboard, a rhythm section, and your own ear at the center — so the sound and the shapes lock in together. WHAT'S INSIDE • Play-along backing tracks — walking bass, brushed ride, and jazz guitar comping over ii-V-I, jazz blues, turnarounds, and more. Set any key and tempo and play over it. • The fretboard, shown honestly — chord tones colored by role (root, 3rd, 5th, 7th) across shell, Drop 2, Drop 3, and rootless voicings, in every key. • Any Chord — build or identify any chord, see it voiced on the neck, and find it inside a key. • Ear Training — intervals, triads, 7th chords, and cadences, with a difficulty curve that grows with you. • A 16-stage guided path — from the four chord qualities to real standards, in plain English, with a glossary for every term. • Practice streaks that keep you coming back. FREE TO START Learn with shell voicings, the major ii-V-I, and core ear training at no cost. Unlock Pro once — no subscription — for every voicing type, all the play-along progressions, five jazz standards, and the full ear-training set. Built for adult players who want jazz harmony to finally click. Bring a guitar.
