Cyril Bradley Rootham (CBR) was director of music at St John's College, Cambridge from 1901 until his death in 1938. During his tenure, he composed many sacred works both for the College and for Westminster Cathedral and others.
This web page is still "work in progress". Eventually the page will contain score files with playback for CBR's anthems, canticles, hymns and carols.
Playback with score pages in sync is generated by MuseScore. Start the player, then press F to view the score full-screen.
Choir members can either watch and listen to MuseScore playing each voice part, or download the MP3 audio and MP4 video files for practice (right-click, then "Save link as...").
