The Concerto line of outdoor musical equipment allows children of all abilities to experience the joy and benefits of making music. Designed at a more accessible angle and height, these instruments can be played comfortably by all kids, including those with mobility devices. Both the Vibes and Chimes are tuned on a diatonic scale, which means that kids can achieve more accurate musical notes and learn to play real songs. Each has good sustain when struck with the attached rubber mallets, immersing children in sensory stimulation from the vibrations. Concerto Cabasas produce a metallic rattle as they spin, ranging in frequency depending upon drum size. Kids will keep the rhythm as others join in on the Congas, which differ in diameter and length to give each one a unique tone.
