Strings
This experiment lets you explore the natural mathematical relationship between a string’s length and its pitch. Several strings are available to play, with each being divided into different lengths.

Oscillators
This tool lets you explore how the shape of a wave can change the sound it makes. You can choose from four different waveforms including square, sawtooth, triangle, and sine. When you click (or touch) from the top to the bottom of the screen, the wave will play from high to low.

Piano Roll
This tool is a simulation of an old-time piano roll. You can play the music and see the notes scroll by. There are different songs to choose from and instruments to play.

Harmonics
This tool lets you play notes in a harmonic series, which is a set of frequencies with a simple relationship, such as twice as fast, three times as fast, four times, and so on. This can lead to an exploration of musical intervals, octaves, and major chords.
