Not sure I'd want to pay much attention to someone who found Palestrina boring. I hope he came to his senses in later life.
Grumble.

No need to pay attention to an anonymous composition teacher's childhood opinions. I'm glad Andrew enlightened to some degree the meaning of this rather totally rare word
semasiology. I have no particular opinion on Palestrina, but his name in this context reminded me of the old hit " Whiter Shade of Pale". Words, just words.
Maybe etaoin will have more to add. The music expert.
