One tap deals a full improv prompt: key, scale, tempo, mood and duration. Lock what you love, reshuffle the rest, and never face a blank session again. Blank-page paralysis kills more practice sessions than a lack of talent. You sit down, pick the same key you always pick, noodle the same licks, and call it a day. Jazz Improv Practice & Scales fixes that with one tap: it deals you a complete improv prompt — key, scale, tempo, mood and duration — so the decision is made and the only thing left to do is play. Most practice apps hand you a metronome and a chord chart and leave the hard part to you. This app is built around the prompt. Five cards, each one a real musical constraint. Lock the ones you want to keep, reshuffle the rest, and every session lands somewhere you would never have chosen on your own. WHAT YOU GET • Sit down and start playing within seconds — no more deciding what to practise • Stop hiding in C Major: 12 keys × 12 scales dealt at random, biased toward your instrument • Grow one variable at a time — hold your favourite key and let the scale, tempo or mood change • See the exact notes of any scale in any key, with intervals and a plain-English character sketch • Set the groove before the first note with a visual, haptic and click metronome at the dealt tempo • Keep the prompts that sparked something, add a note about what worked, and find them again by search PERFECT FOR • Guitarists and pianists who want to escape the two scales they always fall back on • Horn and string players building fluency across every key before the next gig • Jazz students working through modes, harmonic minor, whole-tone and diminished • Bands and duos who need a shared constraint to jam over in rehearsal WHY NOT JUST PICK A KEY YOURSELF? Because you will pick the comfortable one. A dice roll has no habits. The app pairs a random draw with per-card locks, a tempo feel label from Ballad to Burning, and a session history you can rewind — structure that a coin flip or a scrap of paper will never give you.
