Answer:
Make noise and is really cool!
A trombone can do more than make noise and yes, it is really cool what is does. A trombone is good for slurs in music because of the slide mechanism. If anybody thinks that the trombone is hard to play, it isn't hard to play. If you regret playing the trombone, it is worth it! I have played trombone for two years and I am trying to be a trombone extraordinaire or a master of the trombone.
