The Land of Grimney - The Illustrated Adventures of Cora Pearl, aged 12

Barritone liked to share
A Mezzo-Soprano
with the Rock group
When Falsetto
blew the whistle
In Contralto
To the Vibrato Bass
Which upset her Posture
& Breathing
But still the Countertenor
Raised his Voice
In Vocal Fry
The result was Classical!
Tone less Singer
Who claimed to be a Soprano
Caused much Renaissance
The Choir went A Capella
When the Conductor lost his sheet
& the rest went off beat
As he pressed his keystroke
Which was his Temperament
Then Trio began to talk,
Gossip being their Resonance
Exclaiming;
What the baroque!
