Claim:
A musical aid for use with a musical keyboard, comprising: an elongate body having at least three ridges extending outwardly from and longitudinally along the musical aid, each ridge having two side surfaces, at least two different side surfaces of the at least three ridges carrying respective sets of key-indicating markers, each set of key-indicating markers representing a different group of one or more types of musical pattern; wherein adjacent ridges of the at least three ridges are shaped to form a concave surface between the adjacent ridges, the concave surface extending longitudinally along the musical aid; and the key-indicating markers of each set are spaced such that when the musical aid is located on the keyboard in an orientation in which a selected side surface is at a position at which a root key-indicating marker of the set carried by the selected side surface is positioned above any key of the keyboard, the key beneath the root key-indicating marker forms the root note of a group of one or more musical patterns of the types represented by the set carried by the selected side surface, and the remaining key-indicating markers of the set carried by the selected side surface are positioned above keys of the keyboard that correspond to the remaining notes of the group of musical patterns.
