This large, vinyl keyboard mat is perfect to use with preschoolers and beginning music students to walk-on and play games. The 24" x 72" mat accomodates a one-octave scale in any key and rolls up for storage. Reinforcements for hanging are not included. The alphabet note discs (sold sparately) fit nicely on this keyboard. Consider purchasing two sets of alphabet note discs to accomodate the duplication of the octave in scales.
