She started playing the piano as soon as she could reach the keys. After winning many scholarships and prizes at Edinburgh University, and subsequently at the Royal College of Music, she won a scholarship from the Austrian Institute to spend a summer studying piano accompaniment at the Mozarteum in Salzburg.

Since then, Anna has enjoyed a busy and varied career as pianist and piano teacher. Engagements have included recitals, both solo and as chamber musician and accompanist, in many venues in London and elsewhere, in Britain and abroad. She has recently played Gershwin’s Rhapsody in Blue with the St Albans Symphony Orchestra in St Albans Abbey, and Beethoven's Third Piano Concerto with the Buckingham Chamber Orchestra. In recent years, she has twice played Grieg's Piano Concerto with the Hertfordshire Philharmonia, and she has also played Mozart's Concerto no. 21 and Rachmaninov’s 2nd Piano Concerto with the same orchestra. She has played harpsichord in a performance of Bach’s Brandenburg Concerto no. 5 with the Buckinghamshire Chamber Orchestra. She has recently participated in festivals in Rayleigh and Canterbury, and given concerts in, among other places, Edinburgh, Manchester, London, and Provence. In July 2006, she was nominated for the title of "Performer of the Fringe" at the Buxton Festival.

Anna has undertaken such diverse activities as playing background music in London hotels and restaurants, touring the UK and Channel Islands with the Lewis London Ballet, and acting as repetiteur for opera groups and choral societies. She is a Senior House Pianist at the Ardingly International Summer School, and is Neil Jenkins' accompanist of choice at his masterclasses around Britain. Recently, she has worked with the tenor Ian Partridge at a workshop in Somerset.

Anna currently teaches piano and accompanies at St Albans High School. As well as working with the Chiltern Choir, she also accompanies the Aeolian Singers in Hemel Hempstead, and is much in demand as an accompanist for singers and instrumentalists. Anna has recently performed Shostakovich's 2nd Piano Concerto in St Albans Abbey, and forthcoming concerts can be viewed at her website, annalehair.co.uk.
