Features
Everything you need to write music

Step-by-Step Wizard
A 4-step guided workflow walks you through tempo, rhythm, pitch, and articulation. Perfect for beginners with no music theory background.
Real-Time Notation
Every note you enter is instantly rendered as professional sheet music using VexFlow. Supports accidentals, dotted notes, hairpins, ties, slurs, and 8va markings.
Multi-Instrument Playback
Hear your score in piano, organ, strings, guitar, marimba, or brass. Real piano samples via the Tone.js audio engine.
Built-in Metronome
Practice with an accurate online metronome. BPM 20–400, time signatures 2/4, 3/4, 4/4, 6/8. Pendulum animation and downbeat/upbeat sound distinction.
Export & Print
Download your score as a high-resolution PNG image, MIDI file, or JSON. Print directly from the browser for physical sheet music.
Auto-Save & Share
Your work is automatically saved every 2 seconds. Share your score with a URL link. Restore previous sessions with one click.

Classic Library

How it works
Create sheet music in 4 steps
Set Tempo & Key
Choose a title, BPM, time signature (e.g. 4/4), and key signature. Defaults (120 BPM, 4/4, C major) let you start immediately.
Place Rhythm
Fill each measure by selecting note durations — whole, half, quarter, eighth, 16th, 32nd notes and rests. The editor prevents overfilling a measure automatically.
Assign Pitches
Navigate through each note and assign a pitch (C–B), octave, and optional accidental (sharp, flat). Use the quick-fill button to set all notes to C4 and adjust from there.
Play, Export & Share
Hit play to hear your score, then export as PNG or MIDI. Switch to free edit mode for advanced edits like hairpins, slurs, and articulations.
