What is the scale degree name for notes starting on the fifth note of the scale?

The fifth note of a scale is referred to as the dominant. In music theory, the dominant serves as a critical point of tension and resolution within a scale. It often leads back to the tonic, or the first note of the scale, creating a strong relationship and sense of pull towards resolving the harmonic structure.

In tonal music, each note of the scale has a specific function, and the dominant plays a key role in establishing the tonality. It is usually associated with the V chord, which is important for creating harmonic progressions that culminate back to the tonic. This relationship is central to the practice of Western music and serves as a building block for much of its harmonic language.

Understanding the role of the dominant enhances one's ability to analyze musical compositions and understand how melodies and harmonies interact.
