Horizontal axis → Time

Left to right is time. Drawing further right plays later. A horizontal line is a sustained note.

Vertical axis ↑ Frequency

Bottom is low frequency (bass). Top is high (treble). Higher on the canvas = higher pitch.

Brightness → Volume

Brighter marks are louder. Use the volume slider to set the draw intensity.

How to draw music

Each mark is a sound instruction. The tool reads your drawing column by column and plays what it finds. Here are some shapes to try:

Dashes = staccato notes
Diagonal = rising pitch
Parallel lines = a chord
Soft blob = swelling note

The science briefly

A spectrogram shows sound as an image — frequency on Y, time on X, amplitude as brightness. Every sound has a spectrogram fingerprint.

This tool runs that in reverse. Your drawing IS the spectrogram. It reads brightness at each frequency row and reconstructs audio by summing sine waves (or triangles, saws, squares) at the right pitches and volumes — additive synthesis from a painting.

Deaf musicians like Evelyn Glennie have read spectrograms for decades. This lets anyone draw in that language.
