For the smaller groups and for the winds, brass and percussion, you can decide amongst yourselves who will play 1st or 2nd, etc.
For the larger string ensemble I have provided seating.
The principals in the string piece will have to do a bowing cycle. The concertmaster will start this by doing the bowings for the first violin. The principal 2nd will receive those bowings and do the 2nd violins. The principal viola will take both those parts and do bowings for the violas and so on.
The chamber groups will be updated as more are created and I will set a deadlines for each groups to upload their recordings.
