Here a piece I wrote this week. It has 6 parts for strings.
I did cello divisi, but not sure if that's the best option. I could split violin II, but I'm afraid the lows would be too prominent. Violas are the weakest of the strings instruments. If I divide violas, would be even weaker, so I decide to split Celli. Do you think that's the best option for a good balance?
I have been exploring here a harmony rich in suspensions and apoyaturas.
