Want to develop a sense of rhythm? Do you want to accurately perform complex rhythmic patterns? NEW — POLYRHYTHM MODE Two hands, two counts inside one beat. Start with 3 against 2, the one every musician meets first, and work up through 4:3, 5:4, 5:3, 7:4 and 7:5. Every ratio is a ladder of four stages: the right hand alone, the left hand alone, both hands at half tempo, then both up to speed. - Two tap zones, one for each hand. Every hand is scored on its own, so you can see which one is drifting and by how much. - Read the cycle as notation or as two turning rings — the same exercise, whichever way makes it click for you. - Give each hand its own instrument, so the two lines stay apart by ear. - Practice runs the cycle without end and lets the tempo follow your hands: up a step when the cycle comes out clean, back down when it doesn't. It remembers the fastest tempo you held clean for every ratio and every stage. - With a MIDI keyboard, each hand gets its own half of the keys — or a key of its own on pads, where pitch says nothing. - Polyrhythm accuracy is kept apart from your rhythm statistics: it trains a different skill and belongs in its own tally. RHYTHM TRAINING Rhythm is an app that uses flash cards to develop a sense of rhythm. The exercises and classes in the app will help you gradually learn to recognize and play rhythmic patterns at different tempos. Training sessions are graded from beginner to advanced levels in simple, complex, and irregular time signatures. With regular practice, these drills will help you learn to read notes and rhythm from a sheet of music. Classes with a metronome and a drum kit will help children and beginners learn complex musical drills. If you play guitar, piano, bass guitar, or drums, you can choose your favorite musical instrument in the settings. If you are looking for a replacement coach, teacher, teacher, music tutor, then our apps will help you: - learn to read musical notes; - develop a sense of rhythm; - accurately play rhythm by rhythmic patterns; - develop musical and rhythmic hearing; In the app, you can create worksheets with tasks, taking into account the skills of the student and the accuracy of playing a musical instrument.
