What is the memory rule of major and minor in staff?

First of all, you should know what goes up and what goes down.

Let's start with the sharp sign, #, which consists of four lines. You need to see which line or room the pattern like "mouth" in the middle of the four lines passes through.

You see, the number # in G major is the line where the high note 4 passes through the staff, so it should be raised by 4.

If there are two sharp numbers, the first one is a sharp 4.

The second sharp sign passes through the room where the high note 1 is located, so 1 should be raised. So if there are two sharp numbers in front, it is 4, 1.

Then three sharp corners, four sharp corners and so on are all the same.

Then let's talk about flat signing.

The notation of the semitone symbol is B. You can see which note the semicircle passes through, so it is a semitone.

For example, a flat sign. The semicircle crosses the line of 7, so it should drop by 7. Then the second, third and so on are all the same.

2. Know the letter corresponding to each sound: 6A.

5G

Thirdly, next, we decide what key it is according to the number of rising or falling semitones in the score.

First of all, we should remember that a sharp semitone is in G major and a flat semitone is in F major, because the tonic is G or F, which is a method without special memory. Just remember that the rest are regular.

Let's start with the horn:

Look at how many sharp corners there are first (for example, there are four sharp corners).

What's the last sharp corner? (#4, # 1, #5, #2.

So the last one is #2)

Then find the last semitone and count it up by half a tone (two degrees) (the last semitone is #2 and the upper part is 3).

Then this semitone is the major you want to determine (that is to say, 3 is the tonic and 3 corresponds to E, so it is E major).

Minus sign:

Look at how many flats there are first (for example, there are four flats).

What is the penultimate flat sign? (b7

b3

b6

B2, the penultimate is 6)

The penultimate flat note is the tonic of this key (b6 is bA, so it is a flat major).

Fourth, minor corresponds to major:

The minor tonic is the major tonic, counting down three degrees.

A semitone rise or a semitone fall remains the same, except that the minor should be raised by seven levels, that is, counting up from the first note in the minor to the seventh note, and then rising to the seventh note.

For example, C major corresponds to A minor: 6.
