There’s generally an invisible yet real gulf between amateur musicians and amateurs. It’s just as much in the mind as in the fingers.

The Contemporary Music Association – CoMA – a national organisation, dedicated to enabling amateur musicians to get involved in exploring and performing contemporary music, made up of pros, seems to find a way round the professional brambles and nettles and by being non-compromising and genuinely enthusiastic blends the two. All in the desire to fertilise the genre.

Sunday’s concert was the culmination of collaboration between CoMA London Ensemble and the new CoMA Corsham group. And the Corsham group has as its instigator and leader none other than the enthusiastic Nicholas Keyworth, artistic director of the festival.

Each group played its own pieces and joined forces in a vibrant exhibition, if you like, of how much fun and intrigue – and serious musicianship – there can be in contemporary music - all under CoMA London conductor Gregory Rose.

CoMA Corsham even experimented with music and sounds produced by using returnable plastic water machine containers!

It really is fun and rewarding; it is technically challenging – I know because I took part.
