Quadrilla is a marble-track building system. The new addition to the line is the Quadrilla Music Melody Composer, which incorporates xylophone-like tone blocks into the marble track. As the marbles roll down the track and hit the xylophone bars, a little tune results. This set includes 50 building pieces, 20 marbles, and an instruction book with 14 construction examples.
