The chord clusters within the motets are certainly a change of style for you. I like very much the frequent use of echoing and staggered entries. As you know, I always have in mind the mechanics of performance and I wondered how difficult to sing the clusters would be. I listened to each line individually and in fact each part moves fairly diatonically so the clusters are created by the counterpoint which cleverly makes them so much easier to perform.

I like O, Magnum Mysterium very much, maybe one of my favourite things you have ever done.

I was overwhelmed to receive your anthem and dedication to me. It is a lovely piece and in the same bracket as other settings of the piece – particularly the French versions. It will sound great in a nice resonant acoustic.
