Hear exactly what's written
Music Calculator turns the notes on the page into accurate sound. Enter a passage and play it back with precise pitch, timing, and tempo — so you can check a tricky rhythm, confirm what a bar should sound like, and learn it by ear as well as by sight.
Write Any Passage
A fast, calculator-style keypad makes even complex notation quick to input. Tap notes and rests, drag to change pitch, and add accidentals, articulation, ties, and dots. Supports every standard key signature, simple and compound time, complex and nested tuplets, and note values down to 1/128.
Hear It Instantly
Play any passage back with accurate pitch and timing across 25 melodic and 16 percussive realistic instrument sounds. Hear exactly what is written, the moment you write it.
Master Your Music
Slow the whole passage down, loop it on repeat, and practise alongside precise playback. Build accuracy, sharpen your sight-reading, and grow your musical confidence one passage at a time.
