Each orchestral musician needs to be aware of his or her role within each phrase – are you playing the melody, countermelody, harmony, rhythmic pulse – and the relative importance of each. Note lengths, articulation, phrase direction – listening to your fellow orchestra members and fitting your part appropriately.
Say yes to most things, until you’re in a position to say no, and then recommend others for those things instead. Collaborate widely. Be hugely proactive. Put on your own gigs, start your own hubs/websites/record labels. Connect people and celebrate the success of others. Throw all the things you’re interested in into your work and don’t worry about trying to fit in a box.
