How to Use This Workspace
This workspace is designed for single-staff melodies and simple chord voicings. It is not a replacement for full notation software, but it handles the most common tasks without any setup.
Placing Notes
Select a note value from the toolbar, then click anywhere on the staff. The vertical position determines the pitch. The horizontal position determines the beat within the measure. Notes snap to the nearest line or space. If you place a note in an occupied beat, the new note replaces the old one.
Playback
Press the Play button or hit the Space bar. The workspace uses your browser's built-in audio, so the sound is a simple sine wave. It is meant to check pitch and rhythm, not to produce a finished recording. Tempo is adjustable from 40 to 200 BPM.
Key and Time Signatures
Choose from six common key signatures and two time signatures. The key signature affects which accidentals are displayed. It does not yet transpose playback (all notes play at concert pitch).
Common Mistakes Beginners Make
- Writing notes that cross bar lines without ties. If a note lasts longer than the remaining beats in a measure, split it into two notes connected by a tie.
- Forgetting the key signature. In G major, every F is sharp unless marked natural. The workspace shows the key signature but does not auto-apply accidentals.
- Uneven rhythm spacing. Notes should be spaced proportionally to their duration. The workspace handles this automatically.
- Too many beats per measure. In 4/4 time, each measure holds four quarter-note beats. The workspace prevents overflow.
Exporting
PDF export generates a print-ready page with your staff, title, and date. MIDI export creates a standard MIDI file that you can open in GarageBand, MuseScore, or any DAW. Both exports happen entirely in your browser. No data is uploaded.
Edge Cases
Triplets are not directly supported yet. Write them as three eighth notes and mark them with a "3" above the beam in your own annotation. Ties can be approximated by placing two notes of the same pitch in adjacent beats. Dynamics (piano, forte) are not notated but can be added as text after exporting to PDF.
What Gets Saved
Your notes, key signature, time signature, tempo, and measure count are saved to your browser's local storage every time you make a change. Clear your browser data and the project is gone. Use the Share Link button to encode your project in a URL you can bookmark or send to someone else.
