High notes of the harp

fine plucking against the window pane

cascading ripples to the lower strings

a volume increase

a tempo change

the timpani rumbles

a warning grumble

the black-grey opens

with a rattling of sticks

against the snare drums edge

before the drum is beat hard

as heavy rain falls

and the xylophone joins the band

with dissonant chords

and cymbals clash

adding to the cacophony.

When tyres swish through the flowing mass

then abruptly swept is an invisible baton

bringing to an end with a sudden halt

all but the cymbals and harp

the fluttering of strings

from base notes to top

plinking and tapping on the window pane while

the cymbals fade

as the sun peeks out from behind the grey

and the storm concerto concludes.
