Check these blocks out. They play music. One block, the base block, is the control block. This is the block that plays the music and responds to controls. The controls – they are the other blocks. Each block, depending on weight, adds volume to the music. To switch to a new track, turn a stacked block. Beware of using these blocks in high-traffic areas – birds, cats, and girlfriends, because if the blocks are knocked: no more music!
