DMUS_SUBCHORD

The DMUS_SUBCHORD structure is used in the SubChordList member of a DMUS_CHORD_PARAM structure.

typedef struct {
    DWORD dwChordPattern;
    DWORD dwScalePattern;
    DWORD dwInversionPoints;
    DWORD dwLevels;
    BYTE  bChordRoot;
    BYTE  bScaleRoot;
} DMUS_SUBCHORD;
 

Members

dwChordPattern

Notes in the subchord. Each of the lower 24 bits represents a semitone, starting with the root at the least significant bit, and the bit is set if the note is in the chord.

dwScalePattern

Notes in the scale. Each of the lower 24 bits represents a semitone, starting with the root at the least significant bit, and the bit is set if the note is in the scale.

dwInversionPoints

Points in the scale where inversions can occur. Bits that are off signify that the notes in the interval cannot be inverted. Thus the pattern 100001111111 indicates that inversions are allowed anywhere except between the fifth and seventh degrees of a major scale.

dwLevels

Bitfield showing which levels are supported by this subchord. Each part in a style is assigned a level, and this chord will be used only for parts whose levels are contained in this member.

bChordRoot

Root of the subchord, where 0 is the bottom C in the range and 23 is the top B.

bScaleRoot

Root of the scale, where 0 is the bottom C in the range and 23 is the top B.
