Derryck is a graduate of Trinity Laban Conservatoire of Music and Dance and is in the process of completing his second year of postgraduate studies with the aid of the Jonathan Horsfall-Turner Scholarship, the Rhona Reid Trust and Trinity Laban Scholarship. During his undergraduate years, he studied the French Horn with Michael Murray and has subsequently been studying with both Michael Murray and Stephen Stirling. He began learning the Horn at the age of 13, when he joined the Sutton Music Service under the tuition of Adam Walters. Derryck has performed with the Music Service at major U.K venues including the Royal Festival Hall and Birmingham Symphony Hall. Other venues he has performed at include the Royal Albert Hall, Queen Elizabeth Hall, Barbican Centre, Cadogan Hall and many more. Derryck was the 2009 winner of the coveted Cheryl Jenkins award for outstanding performance and musicianship in the Music Service.
In collaboration with the Music Service, Derryck participated in workshops with the London Mozart Players, culminating in a concert at Fairfield Halls, in which he played principal Horn, performing Festive Overture by Shostakovich and Mahler’s 'Symphony No. 1'.
A keen ensemble player, Derryck has performed with many amateur and semi-professional orchestras all over London – including Epsom, Fulham, Aurelian, Guildford, Surrey Philharmonic, Forest Philharmonic and the Mahler Orchestra.
