Music Theory

Wolfram|Alpha's deep algorithmic knowledge makes it a perfect companion to explore computational music theory. Examine the sonic properties of musical notes, find named scales containing a given sequence of pitches, apply pitch‐set operations to note sets and scales and visualize chords, keys and more.
