The document discusses music theory concepts related to major scales, including: 1) A major scale is built on the pattern of whole tones and semitones between certain notes, with semitones between the 3rd and 4th, and 7th and 8th notes. 2) The first note of a major scale is called the tonic, and the scale is named after this note, such as the key of C major or F major. 3) A key signature shows the notes that are always sharp or flat in a piece of music, helping identify the key or scale being used.
