Most humans and at least one parrot like to dance. That involves extracting the tempo from a song and projecting that tempo onto a regular pattern of non-sound-generating movement. That projection occurs at a low cortical level of perception-action cycles. Projection works in the opposite direction, too. Sid Caesar and Nanette Fabray’s Argument to Beethoven’s 5’th is not just brilliant acting; it also shows a fundamental source for musical composition.
