A major scale consists of seven distinct notes.
In Western music, the major scale is built using a specific pattern of whole and half steps. The formula for the major scale is: whole, whole, half, whole, whole, whole, half. This pattern creates seven unique notes that form the scale. The eighth note is simply the octave, which is a repeat of the first note but at a higher pitch.
For example, in the C major scale, the notes are C, D, E, F, G, A, and B, totaling seven notes. Each major scale follows this seven-note structure, no matter which root note it starts on.
