Bach In Lights is a music visualization, based on Bach’s Prelude And Fugue In C (Well-Tempered Clavier, Book I, No.1), performed by Pierre-Laurent Aimard.
The video is a 3D animation, created as a promo for Sinfini Music. Director Alan Warburton animated thousands of CGI lights, each tailored to the precise duration of Aimard’s note strikes.
This was done, with the help of pianist and visualization specialist Matthew Bain, by recreating Aimard’s piano performance as MIDI data. This data was then ‘linked up’ to the data from Alan’s 3D lights model, so that every light responded to the right note at the right time, for the correct length of time.
