What are the major notes in music and how do they contribute to the overall composition of a piece?

The major notes in music are the seven notes of the major scale: C, D, E, F, G, A, and B. These notes form the foundation of a piece of music and are used to create melodies and harmonies. Each note has a specific pitch and relationship to the other notes, which helps create the overall sound and mood of a composition. By combining these notes in different ways, composers can create different emotions and convey their artistic expression in a piece of music.
