When this book begins, the trombone is playing all by itself. But soon a trumpet makes a duet, a French horn a trio, and so on until the entire orchestra is assembled on stage. Written in elegant and rhythmic verse and illustrated with playful and flowing artwork, this unique counting book is the perfect introduction to musical groups.
