Contrapose vs MusicBall

Break through practice plateaus and creative blocks with Contrapose: your pocket-sized practice coach for piano. TWO PRACTICE MODES GENERAL PRACTICE MODE Draw thoughtful prompts designed to deepen your awareness and technique: • Physical awareness (breathing, tension, touch) • Active listening (recording, acoustics, overtones) • Tempo control (elastic time, silence, rhythmic displacement) • Musical expression (dynamics, gestures, phrasing) • Piano technique (pedaling, voicing, hand independence) The app intelligently rotates through practice areas you haven't worked on recently, ensuring balanced development across all skills. IMPROVISATION MODE Spark creative exploration with randomized constraints: • Mood cards set the emotional tone (playful, somber, introspective) • Technical cards provide creative boundaries (form, rhythm, pitch, hand position) Each combination creates a unique creative challenge—perfect for warming up, creative breaks, or developing improvisational confidence. FEATURES • 73 professionally designed practice cards • Intelligent card rotation prevents repetition • Two distinct practice modes for different goals • Complete library to browse all available prompts • Clean, distraction-free interface • Works offline—no account required • Privacy-first: your data never leaves your device WHO IS THIS FOR? • Piano students looking to diversify their practice • Teachers seeking fresh approaches for lessons • Improvisers wanting creative spark • Anyone tired of mindless repetition PHILOSOPHY Contrapose is built on the idea that constraints unlock creativity. By focusing your attention on one specific aspect of playing, you develop deeper awareness and break habitual patterns. Whether you're working on a sonata or improvising freely, these prompts help you practice with intention.

Drop in a song. Watch a machine get built to play it. MusicBall takes a piece of music and constructs a whole contraption around it — plates, curving rails, spiralling drops. Then a ball falls through the lot, and every note you hear is the ball hitting something. It's oddly hard to stop watching. EVERY SONG GETS ITS OWN MACHINE Change the song and everything changes. A gentle piece grows tall spirals the ball winds slowly down through. A fast one packs tight columns it ping-pongs between. Switch back and forth and you'll never see the same machine twice. YOU'LL START TO SEE THE MUSIC Every note has its own colour, and it keeps that colour wherever it turns up. A few minutes in and you're spotting a melody's repeats on the wall before you hear them come round again. PICK WHO PLAYS THE MELODY Hand the tune to a different part and the whole machine rebuilds around it. Or let the spotlight travel between parts as the piece goes on — the ball slides across to a new rig each time the lead changes. Or run two balls at once, side by side. EVERY HIT LANDS ON THE BEAT The ball never fakes it. It arrives exactly when the note does, every single time — so what you're watching and what you're hearing are the same thing happening. BRING YOUR OWN FAVOURITE Seven classics are built in to get you started: Canon in D, The Entertainer, Turkish March, In the Hall of the Mountain King, Für Elise, Prelude in C and Gymnopédie No. 1. After that, bring in anything you like — your file stays on your phone. FLY THE CAMERA Ride along with the ball, or take over: spin around it, pan across the machine, pinch to take in the whole thing at once. NOTHING TO SIGN UP FOR No account. No ads. No tracking, nothing collected. It works exactly the same in Airplane Mode.
