George Collier, The New York Times

Alice Zoo photographs star music transcriber George Collier for The New York Times.

“Music can be a bit uptight, particularly in the whole music theory land,” Collier said during a break between lectures, as he video chatted from a light-filled campus building where the sounds of bustling university life swirled around him.

In his videos, made with the help of a team of transcribers, he deciphers mesmerising cadenzas, barbershop quartet arrangements, funk jams and jazz solos in an entertaining way that softens sheet music’s reputation as something academic and unforgiving.’
