If Purkinje (brain) cells were as big as oak trees, my head would be 75 miles wide.
This scientific treatise is a follow-up to my earlier brain study of hand-eye coordination in drawing (see below) but with the added element of sound, that is to say music, with a close examination of the all-encompassing neural activity involved in performing a solo guitar arrangement of Beethoven's Für Elise.

As an artist-scientist, I've often practiced the following exercise: I draw a picture of some object while looking only at that target object and not at the pen hand or the drawing itself until it is done (see Teacup example). It's called blind-contour drawing. The finished drawing does not match up very well with the overall form of the original object. Unlike tracing the borders of an object through a transparent overlay, there's no visual comparison allowed to help my unseen pen emulate on a remote sheet of paper the path that my eye follows around the isolated target object. My earlier investigations into the disfigured character of blind contour drawings pointed to the basal ganglia as the area of the brain where hand-eye coordination goes astray but I will now examine the role that the cerebellum plays in hand-eye coordination - or in this case, disconnection.
