Abstract: A device (1) for displaying musical relationships includes a display element (2) which is displaceable in a first direction in a holder (3) and is additionally displaceable via the holder (3) along a base element (4) in a second direction running perpendicularly to the first direction, scales (20, 21, 22), chords (24, 25), and their inverses (28) being displayed on the base element (4). The display element (2) has at least one transparent display field (12) and at least one associated chord (24, 25) with the associated inverses (28) being readable in the display field (12) for each tone of a scale. The device is a teaching aid for making the theory of harmony in music understandable Further, elements (40, 50, 60, 70) of the theory of harmony can be placed on the back side of the base element (4).
