Bach’s G major prelude, deconstructed

Another great entry in the Vox Earworm series:

Bach’s six cello suites are considered a rite of passage for cellists. They’re masterpieces of classical music, and the prelude in G major — the first movement of the suites — is perhaps the best example of Bach’s power as a composer. In it, he’s able to achieve rich and complex harmonic movements with just a four-stringed instrument, while using the very basic tenets of music composition. Those basic tenets are what Alisa Weilerstein, a renowned cellist and McArthur fellow, helps us understand.

The prelude will never sound the same after having seen this video.
