A music instruction apparatus. The apparatus includes a support frame (13), a plurality of blocks (22) in rotating connection with the support frame. The blocks are organized in an array pattern of thirteen rows (101-113) and eight columns (121-128). Each of the blocks has a first side (30) that includes indicia representative of a music note (32). When the blocks are oriented such that the first sides of each block are viewable, each row displays music notes that correspond to a major music scale. A subset of the blocks in each row have a second side (34) that include indicia (36) representative of music notes that are a half step in tone away from the first note on the corresponding block. By rotating a selection of blocks to their second sides, the music notes of a minor scale which corresponds to the major scale can be displayed. Each block also has blank side (51). By rotating a selection of the blocks to the blank side, the music notes that correspond to a chord can be displayed. By changing the blocks to display different scales and chords, the apparatus enables a student to interactively practice constructing chords and scales.
