This keyboard mat allows budding virtuosos to compose their own music as they dance, jump, or run on the keys. Fourteen white and 10 black keys--almost two full octaves--produce individual tones or melodic harmonies. Nearly 6' long, the keyboard is large enough for duets, and musicians can record and instantly listen to their compositions or tap along with prerecorded songs. The mat replicates the sounds of eight instruments (piano, guitar, trumpet, saxophone, banjo, oboe, violin, and vibraphone). Requires four AA batteries. For ages 3 and up. 72" L x 30" W. (2 3/4 lbs.)
