The brass peal of encouragement fanfares me to action
And bids me to play myself the highest note as can reach
Balanced on the edge of a scale, my treble-hearted quaver
To hold my tone in purest form until, beyond my fine appeal
I may breathe again
Playing the note is a metaphor of reaching your potential,
and doing your best, and holding up an expectation.
Sometimes you think you will pass out.
