Her first commissions, in the 1970's, were from the Finchley Children's Music Group, the King's Singers, and Peter Pears, but she also wrote 4 pieces for the newly formed Songmaker's Almanac, and a string of chamber works for, amongst others, David Roblou, David Mason, Anton Weinberg, and the New London Consort, one of the first composers to write new music for medieval instruments.
In 1983, she joined the BBC Singers as a full time member of the alto section and toured extensively with them singing many solo parts. She left the Singers at the end of 1995 to concentrate on her activities as a composer, though she continued to sing professionally for some years. Since 2004 she has been Composer in Association with the BBC Singers, a highly successful collaboration which continued to 2009. During this association the BBC Singers made a CD of some of her choral works -'Remoter Worlds,' for Signum. Ed Breen wrote 'this is really wonderful writing and beautifully executed by The BBC Singers.'
She has been involved in many education projects: The Red Hot Nail, written for the LSO, has been performed more than 100 times, including performances in Louisiana, and the LSO also commissioned The Mysteries of Adad for a project at the British Museum. Inside the Mandala was a dance project commissioned by the BBC Philharmonic, and several of Bingham's works have been used as the basis for work in schools. She has regularly acted as a judge in many high profile events like the BBC Young Composer of the Year, and has lectured in many of the British music colleges and in several American universities.
On joining the BBC Singers, she wrote a series of choral works, many of them based on texts compiled from disparate sources as an integral part of the compositional process. These included Irish Tenebrae, A Winter Walk at Noon, and A Hymn before Sunrise in the Vale of Chamonix. Several of these were for the BBC Singers, but there were also pieces for other professional, amateur and collegiate choirs, including Salt in the Blood, written for the BBC Symphony Chorus to perform at the 1995 Proms, a Magnificat and Nunc Dimittis for King's College Cambridge, and diverse anthems and church works for the cathedrals of Winchester, Lichfield, Westminster Abbey, St John's Cambridge, and more recently, Westminster Cathedral, Wells Cathedral and the Edington Festival. She has written 3 settings of the Missa Brevis, and 2 sets of Evening Canticles as well as many anthems. In 2007 she was made a Fellow of the Royal School of Church Music for distinguished services to church music.
Although Bingham's output is marked by the number and variety of its choral works, she has always been seen as an all-rounder, and the scope of her activities has included pieces for brass band, symphonic wind ensemble and various chamber groups and solo instruments, concertos for trumpet and bassoon and tuba, and several impressive works for large orchestra including Beyond Redemption (1995) a BBC commission for the BBC Philharmonic, and The Temple at Karnak (1996). Chartres, a significant work for large symphony orchestra, was performed to great acclaim by the BBC Philharmonic under Jane Glover in 1994, and was recently conducted by James MacMillan in Liverpool Cathedral as part of the BBC/Royal Philharmonic Society's 'Encore' project. She has written a substantial body of pieces for organ including Jacob's Ladder, a concerto written for Stephen Cleobury and Philip Brunelle. A CD of her organ music performed by Tom Winpenny will be released in 2010. The Ivory Tree, a music-drama for soloists, chorus and ensemble, had its first complete performances in Bury St. Edmunds Cathedral in May 2005. A carol God would be born in thee was performed at the King's College Cambridge Nine Lessons and Carols at Christmas 2004 and was released by EMI on the CD 'On Christmas Day'. Recently her works have included See and Keep Silent for the BBC Singers and Guy Johnston, performed on Good Friday at King's College Cambridge, and Shadow Aspect for choir, organ and timpani, written for the Edinburgh Royal Choral Union. A set of solo violin pieces called The Lost Works of Paganini was performed by Peter Sheppard Skaerved on Paganini's violin in Genoa and London. Future commissions include a choral work for the St. Louis Chamber Chorus, and an hour long organ piece for Stephen Farr.
