/*
@interface IDirectMusicPersonality | 
The <i IDirectMusicPersonality> interface provides methods for manipulating personalities.
Personalities provide the Composer (<i IDirectMusicComposer>) with the information it 
needs to compose chord progressions, which it uses to build section segments and automatic 
transitions, as wells as to change the chords in an existing segment as it plays.

It also supports the <i IPersistStream> and <i IDirectMusicObject> interfaces for loading 
its data.

@base public | IUnknown

@meth HRESULT | GetScale | Returns the scale of the personality.
