An Almost Atonal Aria: Constrained Nonsense in Rhyme

Songs in C? Sung gleefully
since singers were pre-natal.
Tunes in F? The favored clef
of yod’lers in the cradle.

C-sharp rounds are rife with sounds
which summon up -weiss, edel-.
Lays in A, chanteuses say,
go dandy with a dreidel.

Duets in B? “The master key, “
claims Hansel’s sister Gretel.
Hymns in G flow gracefully,
like syrup from Mom’s ladle.

Sing airs in D? No sir! Not me!
(Though crooners in Kuwail’ll.)
Chansons in E? De corps esprit!
But strains in A flat? Fatal!
