Abstract: A musical learning system including an instrument and method is disclosed. The instrument is comprised of a rectangularly shaped box designed for convenient handling by an operator in a manner analogous to other musical instruments such as a piano, a guitar, or a horn. Thirteen movable buttons on the top surface of the box sound eight natural notes and five notes of sharps and flats when pressed by the operator, the sounds being produced by either a built-in, acoustic or electronic sound system. Easily removable attachments having instructive musical notations are temporarily secured above and below the buttons can be used in a predetermined sequence, thereby enabling the operator to grasp music concepts over a relatively, brief period of time. In addition, in the electronic version, an “octave-up” switch enables an operator to sound a note one or more octaves higher for each of the buttons; and a “mute” bar allows the operator to silence a note being produced, if desired.
