Mathemagician Vi Hart Explains the Science of Sound, Frequency and Pitch

From the cochlea to Coachella, or what mathematical ratios have to do with the enjoyability of melodies.

You may recall mathemagician Vi Hart from her brilliant stop-motion explanation of the Victorian novella Flatland on a Möbius strip. This month, she’s back with another gem, this time exploring the science and mathematics of sound, frequency and pitch. From Pythagoras to the anatomy of the ear, Hart uses her signature playful hand-illustrations to reveal how simple mathematical ratios make pleasing melodies.

For a semi-related treat, see Jad Abumrad’s fantastic PopTech talk on science, sound and mystery.
