Make drawings in the real world, photograph them with Tunetrace and hear them transformed into music.

When you photograph a real drawing, the image becomes a computer program that generates live music. Watch as Tunetrace gradually translates your photograph into a skeleton of line endings and crossings. Then the real magic begins. Twinkling lights obey a few very simple rules to navigate your drawing, making music as they go.

Change the drawing and you change the music. The rules are simple but the results can be mind-bogglingly complex. Some drawings make music that repeats in a loop, but some become songs that seem never to repeat. Is it possible to make a drawing that plays music that never ends? Delve deep into the utterly unique magical mystery of Tunetrace and you might find out.

Tunetrace is an app that has to be seen and heard to be believed.

Ratings and Reviews



Perfect to interact with your child, do not leave her alone, experiment together. It should be upgraded with new sounds possibilities and more control over the sounds as manual pitch and various instruments (i.e.) I would pay if so with pleasure!!



A University and they don't even know what MIDI stands for....

Very interesting


I was absolutely fascinated by this app lol I was drawing crazy doodles for a couple of hours. Can really see this as an exciting & more creative way off creating music I think more acoustic abilities would really help but as this being a project more things will come of this. Thumbs up from me anyhow :)
