Dominant
The fifth whole note of a scale.
Whole Note
1. An interval consisting of two semitones, that is a whole step.
2. The particular sound of an instrument or voice, as well as the performer's particular coloring of that sound. For example, the tone produced by a certain clarinetist could be said to be rich, dark, and mellow; this is the result of the natural sound of the instrument, combined with the performer's particular technique of playing.
