This is the first year in over 8 years that my high school's trombone section has been large enough to do anything much with. We have 6 trombones and 2 more that can be taught trombone in a matter of a few days. I am looking for a trombone quartet for a average high school trombone quartet (like something that has the basic rhythms up to 16th notes and maybe a little more (just for learning purposes)) and a trombone sextet/choir that has about the same but is more applicable to people with braces. I have looked for several pieces but I also want to know what other people have played and have had experience with.
thanks

A few days? Um, it takes days to really learn trombone. How are they going to pull off a high school level trombone choir if they only have a few days to learn the instrument?
