Professional Violinist for 27yrs; Avid Chamber Music coach. Composers; I think one can not live with out any of them. They are all so quintessential and give every meaning to be a performer as such. Having inherited a massive collection of Orchestral Parts (mainly 1st and 2nd Violin parts; occasionally some Viola as well) from colleagues who have passed away. I have embarked on a 7yr project of getting said parts digitized. It's still in the making.
