Major mode: The beginning note is any note of 135, and it ends with any note of 15. The whole song has 135 as the main note, which is the major mode. ?

Minor mode: Starting with any note of 63, and ending with only 6, it is a minor mode. ?

Each key is divided into major and minor modes?

For example, in the key of C, with 135 as the starting note, 1 as the main note, and 15 as the ending note, it is C major. With the 6th note as the main note and the 6th note at the end, it is the key of A minor. Because the scale 1234567 in the key of C is represented by CDEFGAB. So 1 (do) is C, C is a major triad, so it is called C major, 6 (la) corresponds to the letter A, and A in the key of C is Am, a minor triad, so it is called a minor.

Extended information:

In music, A and B are the names of the seven basic temperaments in the Western music system.

That is, 1 represents C, 2 represents D, 3 represents E, 4 represents F, 5 represents G, 6 represents A, and 7 represents B. The relationship between note name and pitch is absolute; unlike the roll call, which is relative to the note name, the relationship between roll call and pitch is relative. The note names for each octave higher or lower are the same; and the solfeggio can be the same even for different pitches.

In music, the assumed name of the sound used is called the sound name. The note names of the Western music system are represented by C, D, E, F, G, A, and B. They have fixed positions on the staff and keyboard instruments.
