To learn how scales and chords work, we need to understand what a “major scale” is, and what a “minor scale” is. Most music is based on either a major or minor scale, and these two scales are closely related. In reality, few of these combinations are used in music. In fact, there are 462 possible “C” scales we could create using 7 notes in which the first one was “C”. It follows that we could create many scales where “C” is the lowest note, because there are twelve notes and we can complete the scale with any other six. The quality of the scale (major) is determined by the notes in it and their relationship to the tonic A word describing the tonal center of a piece of music, with other tones resolving to this note. Previously, we learned about the musical alphabet and the major scale.
