Markelangelo Labs
Touch the hanging ball and pull — the angle sets the tempo, and the rhythm appears in notation while you hold. Let go, and the count begins: the ball swings on its thread. Every finger can hang another ball.
Features
The whole metronome is a gesture: no buttons, no menus while you play — grab a ball, pull it, let it swing.
Touch the ball and drag: the angle sets the tempo. While you hold, the rhythm appears in musical notation.
Every finger is another metronome: hang up to twelve balls and run different tempi at once. Drag a ball down to take it away.
Beats per bar from 1 to 12, accents — bell, louder, or off — and tap tempo to find the pulse by ear.
Wood, bell, glass and triangle in the base. PRO adds voices tuned to notes and built-in sets: the Russian bell peals — blagovest, perezvon, trezvon — a Greek rhythm, “Twinkle Twinkle”.
