Duration Constants

Note durations are represented using real numbers (floats). For example, 4.0 stands for a whole note, 2.0 for a half note, 1.0 for a quarter note, and so on.

The music library defines the following constants for common duration values:

DWN                        = 6.0
DOTTED_WHOLE_NOTE          = 6.0
