With pieces about bats, Frankenstein, ghosts, invaders of the night, and other enticing characters, there's no doubt about the intended season for this collection. Imaginations will soar while students are playing these "frightful" solos. There is substance in each; teachers will not object to the study time spent on them. They are cleverly written, with good rhythmic interest. And some of them will work as recital pieces long after Halloween is past.
