There are of course tons of use cases for music teachers, especially for introducing concepts including composition, rhythm, arpeggios, and harmonics.

For instance, Oscillators can be a fun way to introduce the x- and y-axes and their usefulness for coding, and Chords and Sounds Waves can both be used to illustrate waveforms and frequency. Since there are only 13 experiments, start by playing around with all of them to see which ones connect with your curriculum, because those connections abound - not just in music but in science and math. Teachers will likely, however, want to offer some guidance rather than let students run wild.

The focus is very much on free-form play and experimentation, and on this front, it'll surely succeed, inviting students to explore and create. Chrome Music Lab is a free website by Google, featuring 13 different interactive musical 'experiments.' There's no instruction or supports beyond some simple iconography and tweets showcasing actual classrooms using the tool.
