Deputy Director

Maryan Balkwill ARCM, GRSM [Profile]

MARYAN BALKWILL was born in London. She studied at the RCM with Antony Pini and also with Joan Dickson, with whom she continued her studies in Edinburgh. Whilst based in Edinburgh, Maryan worked with the Scottish Chamber Orchestra, the Scottish Baroque Ensemble and the Scottish Opera Orchestra, touring in the UK and many European countries. She taught at Glenalmond School, Perthshire, and in Edinburgh at St Marys Music School, the Rudolf Steiner and Merchiston Castle schools.

The beautiful sound, accurate intonation and rhythmic vitality of the young players of the Helsinki Junior Strings inspired Maryan to attend a Colourstrings teacher training course in 1992. A few years later she started to teach using this approach to string teaching. She taught at the Coloustrings schools in London and Kent, until taking a break in 2005/06 to study for a few months at the Kodaly Institute in Kecskemet, Hungary. In Finland she visited the East Helsinki Music Institute to observe musicianship and instrumental lessons where this Kodaly based approach to string teaching was established by Geza and Csaba Szilvay in the 1970s.

Maryan has also taught for Music Services in Buckinghamshire, Oxfordshire, Merton and Lambeth. More recently, in addition to teaching privately, Maryan has taught at Brighton College and at schools in SW London such as Ibstock Place, The Hall School and Putney High School. She was a founder member of the Colourstrings team at Gallions School, Beckton, where she taught for three years. In 2016 Maryan started to teach at Nikhil Dally's music school, 'Stepping Notes'.

She has played in orchestral and chamber music concerts in and around London. For four years in the 1990s Maryan directed a lunchtime chamber music concert series in Wimbledon, 'Midweek at St Marks', in which she also played duos and string quartets. She regularly plays chamber music and is a member of the Auralio String Quartet.

Maryan covered CMS Director, Rachel Erdos' maternity leave in 2017/18 and now continues behind the scenes as Deputy Director.
