After 20 years in the telecommunications and computing industries Richard moved into teaching, initially in further education and then, in 1999, joining the Open University. As a senior lecturer he specialised in teaching data communications, information and music technologies. Before retiring in 2014 Richard embarked on a part-time PhD with the OU, choosing to research pitch drift in a cappella choral singing. Being a back-row tenor in several choirs, including the OU’s choir based in Milton Keynes, he was intrigued as to why choirs drifted in pitch in an irregular way when singing unaccompanied and set out to investigate possible reasons for this phenonium. Earlier this year, he successfully defended his thesis and is pleased to have the opportunity to share some outcomes with members of the ABCD, who kindly supported his research back in 2013.
