I'm having trouble deciding what kind of instrumentation to use for a hip-hop ensemble. After listening to a plethora of different instrumentals the usual format is 2trombones 1 trumpet 2 saxophones usually one alto, and one bari or tenor, but my main issue is the low sounds. I've experimented and I like the combination of trombone and bari for basslines while alto and 1st trombone go at it with the high melodies. I need some advice from jazz people, and classical people, and if people that play jazz/hip-hop styling too. I've never really tried anything like this before any thoughts would be appreciated.
