1 First of all, let me tell you the basic knowledge of music chords:

1. Natural scale: that is, the seven tones contained are natural tones without rising or falling.

Simple musical notation 1 2 3 4 5 6 7 1

Music name C D E F G A B C

Roll call Do Re Mi Fa Sol La Ti Do

In this scale, 3-4 are a semitone apart, 7-1 are also a semitone apart, and the other two adjacent tones are all a whole tone apart. This is also a very important formula in guitar music theory. On the guitar fretboard, a semitone is the distance between two adjacent frets.

2. Changed scale: Changed scale refers to a scale that contains sharp and flat marks. It adds a sharp and flat semitone between each whole pitch of the natural scale. #1 = b2 , #2 = b3 These are homophones, but different names.

2. Chord knowledge

(1) Chords

Chords usually refer to three or more tones of different heights sounded at the same time, and the arrangement of note names There are seven tones C, D, E, F, G, A and B. Any one of them can be the tonic (that is, the root note) plus the upper third and upper fifth to form the most basic third. The chords are described as follows:

C: 1 3 5

D: 2 4 6

E: 3 5 7

F : 4 6 1

G : 5 7 2

A : 6 1 3

B : 7 2 4

The above seventh chords They are all composed of three tones separated by three degrees, so they are called third degree chords. These seven triads are the foundation of all chords.

(2) Triads

The above seven basic triads can be divided into three different types of triads in terms of intervals

1 , major triad

There are four semitones from the tonic to the third; there are seven semitones from the tonic to the fifth. These are C, F, and G among the seven triads above.

2. Minor triad

There are three semitones from the tonic to the third; there are seven semitones from the tonic to the fifth. D, E, and A among the seven triads above are. For distinction, write Dm, Em, Am.

3. Diminished triad

There are four semitones from the tonic to the third; there are seven semitones from the tonic to the third. This is the B in the seven triads above. Written as B-.

(4) Seventh Chords

Since the seven triads above are not enough, adding a third above each triad will suffice to form the following sevens. Seventh chord:

C7: 1 3 5 7

Dm7: 2 4 6 1

Em7: 3 5 7 2

F7: 4 6 1 3

G7: 5 7 2 4

Am7: 6 1 3 5

B-7: 7 2 4 6

Among the seven seventh chords, the fifth note G in the note arrangement, that is, the dominant note, is the most commonly used seventh chord, and it belongs to the seventh chord G7.

Because the four component notes of G7: "5 7 2 4" already include the "5 7 2" of the G chord. Therefore, in terms of harmony technique, the three chords of C, F, and G7 can be used to accompany a major song.

2. Let me tell you how to learn music chords:

1 First of all, you need to know the "principles". The so-called principles are:

All major triads = major third + minor third (for example, C=1 3 5, D = 2 #4 6...)

Any minor chord = minor third + major third (for example, Cm=1 b3 5, Dm=2 4 6...)

Any augmented triad = major third + major third (such as C+=1 3 #5, D+=2 #4 #6 ...)

Any diminished triad = minor third + minor third (such as Cdim=1 b3 b5, Ddim=2 4 b6....)

Then, let me tell you about the dominant seventh chord. The "dominant seventh chord" is a seventh chord constructed on the dominant note, also known as the minor and minor seventh chords. It superimposes a minor third interval on top of the major triad, from the root to the seventh. It's a minor seventh. Because this chord often bases the root note on the dominant note, it can also be called a dominant seventh chord.

So dominant seventh chord = major third + minor third + minor third

For example: A) Major and minor seventh chords == 4 6 1 b3

2 again Let me introduce to you some experiences in learning chords:

(1) You need to have solid basic finger skills to play various chords stably;

(2) Have certain music theory of keyboard instruments Basics: Be familiar with the basic major, third and minor triads, and on this basis, learn the inversions of the first and second chords, that is, sixth, fourth and sixth chords, including root, third and fifth notes, so that you can use chords flexibly without being rigid;

(3) If you have room for learning, you can also learn seventh chords and improve your chord level with others;

(4) Memorize the composition and composition methods of various chords;

(5) Try to learn to add chords to music by yourself under the guidance of orchestration scores and teachers. Remember: it is best not to add chords to outside sounds. If you reach this state, you will be very good;

(6) Don’t be afraid of hardship, practice persistently, and you will eventually become proficient;

I wish you success and hope to adopt it, O(∩_∩)OThank you.
