What is the primary note of a scale that all other notes gravitate around

Answer 1

The primary note of a scale that all other notes gravitate around is called the "tonic." The tonic is the first note of the scale and serves as the home base or central pitch in a musical context. In a major scale, the tonic is the note that gives the scale its name (e.g., in C major, C is the tonic), and it typically provides a sense of resolution and stability in music.
