does any trombonist can improvise their music using trombone?

absolutely! If you've evr heard 'Tutti's trombones' and their imprvisations, you'll be astounded! The trombone is very versatile, and so is good for improvising - it takes time to 'learn' though, I can't do it properly (i.e. confidently enough to make it sound right!!)

I think they are all nearly gone now, check out Mark Nightingale for some real stuff!
