“In C”

This only performs well in Google Chrome and Safari. Occasionally cuts out on slower machines.

“In C” is a musical piece intended to be played by a variable amount of performers. The piece is divided into 53 segments that are to be played, “consecutively with each performer having the freedom to determine how many times he or she will repeat each pattern before moving on to the next.” This performance is truncated from the preferred 45-90 seconds per segment to 7.5-15 seconds per segment if played at 120 bpm.

This pen was inspired by a CodePen-powered performance of “In C” by Bryant Smith at a recent CodePen Chicago meetup, which you can read more about and view a video of here .
