I love tenor saxes...grainger said it best
double stroke snare rolls
suspended cymbal and timpani rolls together
timpani and chime doubling
marimba and low clarinet doublings (really, check out gillingham's piece "Be Thou, My Vision. It's beautiful)
quiet, light sections played by the woods and then fortissimo, ball-shattering brass syncopation (grainger again
)
I could go on...just check out a score of Lincolnshire Posy. It's an amazing sound. Especially the 5th movement. It starts in free time, every note given by the conductor. or the third movement, with high piccolo doubled with low clarinet...or bassoon, i forget which. It's all very good stuff
