Chrome Music Lab — Song Maker

01 / THE THING

What it is

Place notes on a grid and play the repeating musical pattern.

How to play & Controls

1. Click the note grid to add a note, then place another at a different height or time.
2. Select Play to run the pattern and Stop to pause it.
3. Try an instrument or tempo control after the basic loop makes sense.

Controls

The official About panel lists arrow-key movement, Enter and Backspace for adding or removing notes, and Space for playback. In our check, note entry enabled Save and Play changed to Stop. Audio output, saving and sharing were not independently verified.

Is it free

Basic note editing and the playback interface opened without payment or an account. No microphone or MIDI permission was needed for that route. We did not verify every optional input, export or sharing path.

Does it work on mobile

Unverified on a physical phone. The checked route used a desktop browser; touch input, phone audio and optional microphone behavior must not be assumed from that result.

What to try first

Place two notes in different columns, select Play and watch the sequence advance. Move one note higher and compare its position before changing settings. Mic and MIDI are optional for this first exercise.
