Are Pirates Polite by Corinne Demas and Artemis Roehrig. Published by Scholastic.
A fun book for the students, who all love pirates! Mallets 1 are the glockenspiel, Mallets 2 are the alto xylophones, Mallets 3 are the Bass xylophone. Feel free to substitute any instruments you have. Boomwackers always work well. I usually end up adding sound effects with other percussion instruments. The Ocean Drum could add an ocean sound. I teach the song first, then the instrument parts on body percussion, then put it all together. We read and perform the book numerous times to allow for the students to rotate through the instruments each time they come to class.
