Marble Music Track

Place keys, drop a marble, and hear it play a tune. Marble Music is a musical machine you build with your fingers. Every key is a note. Drag one out of the tray, tilt it, and the marble bounces off it and rings it as it falls. Line up a few and you have a melody; add rails to carry the marble across a gap, and a song. HOW IT WORKS • Drag a key out of the tray. Its colour is its note. • Tilt keys to throw the marble left or right. • Add rails to bend the path: straight, curve, scoop, S-bend and wave. • Tap Play and watch the marble run. Undo anything. FOUR INSTRUMENTS Wood keys ring like a marimba, glass like a glass harp, metal like a glockenspiel, glow like a kalimba. Every note is recorded from real instruments, and the physics is exact: the same track plays the same way every time, on every phone. SCALES THAT KEEP YOU IN TUNE The tray only offers notes from your scale, so anything you build sounds right: major and minor pentatonic, major, natural minor, blues, or the full chromatic keyboard when you know what you want. THIRTEEN LOOKS Candy is the default. Behind it are twelve studio looks, from bright wood and brushed metal to dark sweeps where glowing keys light the wall. A SONG TO START YOU OFF Twinkle Twinkle Little Star comes built as a finished machine. Play it, take it apart, move the keys and make it yours. SHARE THE RUN Export any track as a vertical video with sound, ready for sharing. NOTHING TO SIGN UP FOR No ads, no account, no subscription, no in-app purchases. It works with the phone in flight mode, and your tracks stay on your phone.
