The creation of so many indestructable new compounds in this modern age such as titanium, and bubble gum, may eventually lead to indestructable musical instruments. In such a case, one wouldn't worry so much about doing this:
And this would lead to other developments:
1. Since a violin "ages" and gains a better sound by long-term vibrations of the instrument, thus this would lead to using the violin for corporal punishment instead of the whip (which incidentally, is actually an orchestral instrument - listen to the Young Person's Guide to the Orchestra). If done right, this may make literal the expression, "facing the music." OK, lawak bodoh, aku pun tau.
2. The dent-proof tuba... and relatives. Since the larger brass instruments are already in use as punishment either by whacking... or playing with too much spit in the piping, dent-proofness is only a skip away. The only trouble would be that since dent-proof cars would not absorb the shock of a collision, all brass instruments would come with airbags. Actually, many of them already do - connected to the mouthpieces... Just kidding guys!
