Deskbells are the easiest to play, getting a quick response by simply tapping the top of each bell. They come with a song sheet, but we recommend using the 8 Note Bell Song book (available separately), which include 25 songs each with music, words, chord symbols and names of notes and numbers for easy playing. The heavy-duty nylon cases* (purchased separately) make storing and transporting bells easy. Additional music designed for KidsPlay® Bell Sets or any 8-20 note instrument is available separately. We also have color coded cards and an instructional video available for use with these deskbell sets! (Ages 3+)
