・There are various chords, but not all of them are important. There are only 3 important things, and these are called the main trichords. That is, 1) C (1, do) = husband, 2) F (4, fa) = wife, 3) G (5, seo) = lover (p10) is a drama that weaves a husband, wife, and lover (p11)
・ All endings from G (seo) to C (do) are used in most songs that are played normally in the world (p14)
・There are chords that can go and chords that can't go, 1) 1 can advance to anything, 2) 2 can only advance to 5, 3) 4 can advance to anything other than 5, 4) 5 can only advance to 1 and 4, 5) 6 can advance to anything other than 1 (p22)
・Count from “do,” which is the “root sound,” which is the base of chord C, and the 3rd sound “mi,” which is the third sound in Doremi, if you only have these two, the minimum C chord is established, and you can omit the 5th sound “so” (p34)
・ If you enjoy a cocktail, it is better to continue several tips of the same base and proceed with drinking while enjoying the strange formulation, and the maintenance sound also has the same structure.

The reason was that I was drowning in my own good voice and raised my voice from the beginning. In order to use intonation, they suppress their emotions, suppress their voice, and when they finally reach their climax, they explode all at once (p53)
・When you try to sing like a bushi, it becomes like singing as if you were lifting it from one level below the original sound (that is, from a strange sound) (p91)
・The Sanada format is divided into 4 blocks, 1) presentation part 1 = first subject, 2) presentation part 2 = second subject, 3) development part, 4) reproduction part = first theme and second theme are played in the same tone, and the conflict between the two themes is resolved (p204)
・ “Do's ♯” has a higher sound than “Re's ♭,” and the reason for this difference is that when sharp and flat are separate keys, the number of keys increases to the point where both human hands cannot fully play them (p219)
