Compose songs and symphonies with millions of musical combinations! Symphony in B. is an interactive musical toy that comes with 13 colorful instrument pieces and features 15 fun songs. Little composers can play with a flute, guitar, violin, koto, drums, and much more! All they need to do is choose up to 6 instruments, place them in the center of the light-up stage, and press PLAY. If they picked the tuba, sitar, and piano to play Alouette, that's exactly what they’ll get! If they switch the piano for a trumpet and the sitar for an accordion, the same song will sound completely different! Not to mention, this toy orchestra also lets you change the tempo and control the volume. 6 AA batteries are required and included. Recommended for mini musicians 3 years and over.
