I once got chided by an orchestral violinist for writing 'stratospheric violin parts'. 'Why don't you just use the warm and rich open G, D or A strings?' she asked. 'Well, I could.... but then it wouldn't sound like me', I replied.
She was irked.
The truth is, I love high (very high!) violin section writing. It's icy and glassy. There's lots of 'frosty' violin section writing in this piece and a few open low G strings to suit everyone.
