Spiky Airs Trombone Book & CD by Edward Maxwell. This book contains famous works by Haydn, Charpentier and Tchaikovsky, wickedly jazzed up with piano or CD accompaniment. The curious title stems from the first piece in the book "Sharp Pointy Airs", a word play on Charpentier, Grade levels: Haydn Sleek [Grade 5], Sharp Pointy Air [Grade 6], and Tchaikovsky Spiked [Grade 7].
