M is for Music by Kathleen Krull, illustrated by Stacy Innerst

From chapters.ca:
Music and the alphabet have always gone together. Don't kids learn their letters by singing the ABCs? But you've never seen--or "heard"--a musical alphabet like this one. Beloved tunes. Unusual instruments. Legendary virtuosos. From anthems to zydeco, the language of music and the music of language harmonize in one superb symphony. It's a funky fusion for songsters of all ages!
