A sharp, where you'd expect a natural

A sharp, where you'd expect a natural,

A natural, where you'd expect a sharp;

No rule observed but the exceptional,

And then (first happy thought!) bring in a Harp!

No bar a sequence to the bar behind,

No bar a prelude to the next that comes;

Which follows which you really needn't mind --

But (second happy thought!) bring in your drums!

For harmonies, let wild discords pass;

Let key be blent with key in hideous hash;

Then (for last happy thought!) bring in your Brass!

And clang, clash, clatter -- clatter, clang and clash!
