"Have mercy upon me O God" employs alternating phrases with verse and full scoring; the work also circulated as a church anthem. The tempo is much slower than a conductor would take it today, but that reflects the approach which was typical at the time of the recording.
About this recording
It is clear that CBR was keen to promote the use of technology in capturing musical performances - something which we take totally for granted today.
We know that this recording was made in 1927 and that Cyril Rootham was conducting the choir of St John's College, Cambridge, accompanied by an unnamed string quartet. Beyond that, there are few details available: we do know that this was an early electrical recording made by HMV. Here we have only provided score pages up to bar 39, but you can hear the complete 1927 session in a restored version (our thanks to Warner Music Group).
