Lyric

Really interesting!
I know this song, and it's pretty famous, isn't it?
Is that really all there is to it?

Q, First of all, the sound of the melody ... Isn't there a lot of "five-degree sound transitions"?
A, I certainly feel like that's how it started. This must be explained retroactively in the history of music. In the days of Gregorian chant, church music was simple with at most a "five-degree harmonic" in the main melody... And as time went by and the sweet "3rd degree hamori" began to color the songs, "5 degrees" was said to be "5 degrees of emptiness" and came out of the mainstream. And in the end, the use of "5 degrees" is banned!! The reason is that the sound is "sharp" ...
Here, we are talking about hamori, but we are following the idea that just as the sound of a chord matches the transition of sounds, what can be said about a sound transition in a hamori.
In other words, "sharp sound" is a characteristic of "5-degree sound transition", and at the same time, the "rock" color of the melody becomes stronger! This is the interval theory of modern sound carrying.

Q, Wasn't the chord progression interesting and popular in the past?
A, the consideration of the code may indeed be outdated, but...
Do you know what the new index "dissonance intervals" is!?
The number represented by this index is an accurate representation of "the avant-garde degree of the code" and "the degree of stimulation"!
In particular, for "key=C", the "C ionian scale" will function as the main scale. At that time, let's specifically find the new index above "dissonance intervals"! First of all, the code "G7", which is the "dominant seventh", is "2.5", while the code "B7" is
It becomes "3.25" and the number jumps! Actually, I don't know the code with a larger value and can't talk about it here, but I can't wait for the day when it will be put into practical use! That's the root of the code here.
"B7" is used!

Q, a few words about "melody theory"...
A. Nowadays, when it comes to theory, "melody theory" is the mainstream. However, isn't it difficult to learn and master "melody theory"? Then, by learning the new "chord theory" and using it in music, I think that the "melody" will be enriched a hundred or a thousand times! It is said to hurry up, but learning "chords" is effective and important to improve "melody"!!

This time, I tried to answer your questions here!
Music theory is interesting!!
