This musical set of eight building blocks teaches children about the orchestra, its instruments, notes positioned on the staff (the “C” scale) and more. Each block features a musical bar on top, so that when kids line up the blocks, they will produce a xylophone. The set comes with a song book and two mallets, all housed in a carrying case that measures 6 1/2" x 6 1/2" x 9 1/2". Launch date: August 2007.
