A war of notes

I wrote this poem at the request of a teacher after I got out of piano lessons. I was feeling inspired.

My piano is a weapon

with it I shall fight.

However, 

this war is not one of might.

This war is clever

This war is bright

It's not what I think

It's what I write

I don't use words.

I don't use rhyme.

I write with notes.

I write with time.

Bullets made from treble.

Ammunition made from bass.

With my staff I rebel,

by annotations made from grace.

A major chord,

in a minor key.

My flats are legend,

my sharps are mean.

Don't try to conspire,

don't dare to admire.

For when the time comes,

I'll be ready to fire.
