Music is primarily an aural experience. But of the other senses, the visual is next in line. Listeners have long been fascinated with ‘watching’ the music – seeing musicians ‘get into it’ with body and soul, focusing on flying fingers, following along with a score, and reveling in synchronous dance movement. The eyes help to reveal the music – its substance and its structure.

On our watch, since the new millennium, technology has afforded us new possibilities for keeping an eye on music. I have been drawn to these whenever they’ve come to my attention, and have been bookmarking them for two decades. Here, finally, is a place where I can share my fascination. The music is all Bach.
