Basic knowledge of music theory: what is a scale?
Tone level is every tone in the music system, and there are two kinds: basic tone level and tone sandhi. The former has seven independent names in the music system, and the sound emitted by the white keys on the piano keyboard is consistent with the basic sound level. The latter is obtained by raising or lowering the basic sound level.
There are two ways to label the names of basic tones: letter system and singing system:
Alphabetic system: c, d, e, f, g, a, b.
Sing these systems: duo, la, mi, fa, sol, la, xi.
At present, the tone level referred to in the basic knowledge examination of amateur music in China is the tone level. Each tone in the mode scale is called the mode scale. The tonic in each scale is also the I-level key in the modal scale. The tonic of each mode scale is different, but the mark always takes the tonic as I level.
do、re、mi、fa、sol、la、xi、do
Example: C natural major mark:
La, xi, Duo, Re, Mi, Fa, Sol, La
A small natural mark: II III IV V VI VII I.
Major scales are marked with capital letters and minor scales with lowercase letters.
Basic knowledge of music theory 1: an introduction to tonal scales
I prefer to use piano keys for comparison, with white keys below and black keys above. The white tone is what people usually sing do\re\mi\fa\sol\la\si\do. Then you will find a black keys between do and re, a black keys between re and mi, a black keys between fa and sol, and a black keys between sol and la. This is the so-called concept of whole tone and semitone.
Any two adjacent sounds are half a tone apart. Do is a semitone from black keys on the right, and black keys is a semitone from re on the right. Then do to re is a whole tone (semitone+semitone). Then mi to fa are semitones, because there is no black keys in the middle. So we can sum up that the interval arrangement order of major scales is: full half full half full half.
Then why study this? Because from now on, we all have to think with this piano and keyboard thinking. After that, we will learn a lot about interval calculation, which requires you to have a piano keyboard in your head.
Well, as we all know, the guitar starts with the first fret, and each fret is separated by a semitone. For example, the sound of the sixth empty string is mi, so the first fret is fa, the second fret is fa, and the third fret is sol. And so on, it is exactly an octave of the twelfth fret.
When I was in college, I didn't study music at first. I have a friend in the math department. So there's a saying in the math department? Sit and watch five? What do you mean? For example, racing, the second place is in front of the first place, that is, taking two seats and watching one. Therefore, in the curriculum design of mathematics department, it is more and more difficult to learn elementary calculus at first, then advanced calculus, then functions and so on. Then if you don't learn elementary calculus well, you can't continue your study. You can't continue your study until you learn well next semester. In other words, if you try again, you will not be able to graduate normally in your senior year, and you will have to study in your senior year. This is the so-called sitting and watching five.
In fact, we will often encounter such examples in our study. For example, today I'm talking about the concepts of whole tone and semitone. If you don't master it well, the next course will be very confused, and then the difficulty will become more and more serious.
Then in this lesson, you can play guitar sounds on the keys in sequence. For example, the six-string empty string is mi, then the first fret is fa, the third fret is sol, the fifth fret is la, the seventh fret is sol, and so on. Then we will gradually know whether this sound is one sound short or two sounds short of the next one.
So we just said that the interval relationship order of major scales is full half and full half, so I will take C major as an example. So if I want to play the scale in D major now, what should I do from re? Re is everything to mi, mi is everything to fa, fa is everything to sol, sol is everything to la, la is everything to si, si is everything to do, and do is everything to re. So the scale arrangement in D major is: re\mi\#fa\sol\la\si\#do\re.
So what is the most important point in this? It is everyone's sense of sound, and it is necessary to cultivate a sense of sound. Because many students will sing a tune no matter what tune they play. So what I want to say is that on the simple road, you may be able to walk fast at first, but it is easy to get stuck behind. Then we may have to start over here and take the difficult road. You will walk slowly, but you will keep walking.
You may not be used to this practice, because you may never practice it. But for you, this is a new continent, and this is something you must learn again. Some students said? Teacher, I can't solo in D major. Well, that's because you haven't sung in D major, and of course you won't do something you haven't done. So from now on, we should do this exercise to cultivate the sense of sound (singing roll call), so as to help us move forward.

1. The pop-up standard sound is used to listen to the tonic chord and tonic. After listening to the tonic chord and tonic correctly, you can determine what mode you should do.
