Minor: It starts with any note of 63 and ends with only 6 notes, which is a minor.
Each key is divided into two modes: large and small.
For example, key C, which starts with 135, takes 1 as the main key and ends with 15, is a major C. It's a minor with 6 notes as the main key and 6 notes ending. Because the decimal places of c key 1234567 are expressed by CDEFGAB respectively. So 1(do) is C, C is major triad, so it is called C big word, and 6(la) is the corresponding letter A, which is Am and minor chord in C key, so it is called A minor.
Extended data:
In music, A and B are one of the seven basic melodies in the western music system.
That is, 1 stands for c, 2 stands for d, 3 stands for e, 4 stands for f, 5 stands for g, 6 stands for a, 7 stands for B. The relationship between sound name and pitch is absolute; Unlike roll call versus fame, roll call and pitch are relative. Every octave has the same name; The roll call can be the same, even in different pitches.
Musically, the assumed name of the sound used is called the sound name. The music names in the western music system are represented by C, D, E, F, G, A and B, which have a fixed position on the staff and keyboard instruments.
