Quadrilla starts with a beautiful wooden marble run but if you add the Quadrilla Melody Basic Set, a young musician can compose melodies by sending a marble through a series of toned chutes and blocks that chime on impact. Five sound blocks can be arranged in any sequence throughout the run, instructing kids to create their own tunes as they watch their marble spiral downward. A simple instruction manual teaches melody basics picture book-style, and the natural birch materials add a classic, enduring element.
