Category:         Music-Models-Representation

Instances of the ModeMember species model pitches as elements of a mode (e.g., minor) or gamut (e.g., pentatonic on F).
This class can be used as a concrete one (adding a few methods to fill it out), or like the other representational classes (making concrete classes of this species).
In the later case, the value instance variable could hold a number or pitch, and the mode or gamut could be shared.
