THE South West Chamber Choir is due to present a special concert of unaccompanied choral music entitled ?Autumn Leaves? in aid of the Ford Park Cemetery Trust in Plymouth next week. The programme includes madrigals, favourite Victorian part-songs, readings, and part-songs by the local composer, Derek Browning. Formed 10 years ago, this choir of about 20 voices rehearses weekly in term-time, gaining an increasingly wide-ranging repertoire of choral music. Much of the music is challenging, some unaccompanied, and covers a span of some seven centuries, up to and including contemporary works by local composers. Director Jason Smart studied at the Royal College of Music under Sidney Campbell (organ), Thornton Lofthouse (harpsichord) and Herbert Howells (composition), gaining a first prize for music theory and several diplomas, including the ARCO with the Sawyer Prize. For three years he was the organ scholar at St George?s Chapel, Windsor Castle, after which he held a number of organist?s posts in Bristol, and became a fellow of the Royal College of Organists in 1981. Jason specialises in pre-Reformation and Tudor church music. His research and editing have resulted in a Publishers? Association of the U.S. Award for Excellence, as well as the publication of a number of editions including as a member of the editorial panel of Oxford University Press?s Tudor Church Music series. After a childhood which included piano lessons and singing in his local church choir, at Trinity College of Music Derek Browning studied the organ with Harry Gabb and the harpsichord with the Australian harpsichordist Valda Aveling. Derek Browning now lectures for the extra-mural department of Exeter University and the WEA, conducts the Exeter Rehearsal Orchestra, and the Abbas Music Group, a chamber orchestra playing mainly Baroque and early Classical Music. The concert takes place at Ford Park Chapel on Wednesday October 3 at 7.30pm. Tickets at £7 available from 01752 665442.
