The IDirectMusicChordMap interface represents a chordmap. Chordmaps provide the composer (represented by the IDirectMusicComposer interface) with the information it needs to compose chord progressions, which it uses to build segments and automatic transitions. Chordmaps can also be used to change the chords in an existing segment.
The DirectMusicChordMap object also supports the IDirectMusicObject and IPersistStream interfaces for loading its data.
The interface has the following method:
| IDirectMusicChordMap | GetScale |
All COM interfaces inherit the IUnknown interface methods. This interface supports the following three methods:
| IUnknown | AddRef |
| QueryInterface | |
| Release |
