What kind of note in the score is called the dominant note?

In fact, the understanding of each key is how many degrees the original C key is raised in parallel, and the intervals between the various levels remain the same. For example, the key of C is dominated by the 1 of the piano, i.e. (do) 1-2 is a major second, 2-3 major second, 3-4 minor second, 4-5 major second, 5-6 major second, 6-7 major second, 7-1 minor second, and there are 2 minor second in an octave. If it is in the key of D, it is the 2 of the piano as the main note, that is, (do) 2-3 is a major second, 3-4 is a major second, 4-5 is a minor second, 5-6 is a major second, 6-7 is a major second, 7- 1 is a major second, 1-2 is a minor second, and the C key is raised by a major second in parallel, and the song ends with a major note, C is 1, and D is 2.

Ending with 5 is likely to be in the key of G, because the degree relationship between the various levels of the melody needs to be studied to determine it.

Listen to the score described by the landlord seems to be a simple notation, with the first key notation at the end of the major key of course 1, the minor key is 6, but it is not excluded that there is an incomplete termination of the song, the end note is three or five tones, the simple score looks at the upper left corner of the 1 = so, or 6 = a certain to know the tune, the letter of that key is the main tone. The staff depends on the key signature next to the clef, and the ending note is usually the main note.

It depends on its tonality, this is the flat sign, for example, if a flat sign is F major, then its main note is fa....

My dear, the main note of the score is the main note of the first key of the song, and the way to find it is as follows: the main note of the major key is "1 (dao)"; The key lead in minor is "6 (la)". If you look at the key mark "1=x (x represents any letter in c b, such as f)" at the beginning of the score, the pitch of the roll call f is the main note of the song.

If the key of the song is minor, the corresponding key signature should be "6=f", then the pitch of the solfège is the main note of the song, 6 (la).

In addition, in the score of the staff, there is no falling note in the clef, which represents the key of C. The clef is made up of rising marks, and since the first sharp sign in the key is the fourth tone in the ascending scale, as long as the last sharp sign in the clef is found, and the key is found in this sequence by 4 degrees or 5 degrees up, that is, the main note of the song. The clef is made up of falling notes, and since the first flat in the key is the seventh note in the descending scale, as long as you find the last sharp sign in the clef, and one note up from this sequence, you will find the key tone, that is, the main note of the song.
