Well-Tempered Clavicle (2011)

Well-Tempered Clavicle is the 35th book of the Xanth series by Piers Anthony. The title is a pun on the Bach musical work The Well-Tempered Clavier.

The back cover of the book states the following:

"When a walking skeleton named Picka Bones happens upon a trio of melodic pets and a lovely, lovelorn princess, his dull and passionless existence is suddenly filled with danger, excitement, and the temptations of the flesh. For a plague of appalling puns has been unleashed on Xanth, and only Picka's musical gifts have the power to save the enchanted realm from the dire monster who imperils it."
