(i) The sequential chords in C major
- legend
As we learned earlier, chords develop on the principle of third-degree tones. Now, let's construct the triad with each note on the scale as the root tone:
The triad formed on a Do tone, known as "13 5", is denoted C;
The triad formed on the Re tone, known as "24 6", is denoted dm;
The triad formed on the Mi tone, known as "3 5 7", is denoted Em;
The triad formed on the Fa tone, known as "4 6 i", is denoted F;
The triad formed on the Sol tone, known as "57 2", is denoted G;
The triad formed on la tones, known as "6 i3", is denoted Am;
The triad formed on the Si tone is "T Li 4", denoted Bdim.
According to previous knowledge, the root tone of the three chords of C, F, G is the third degree of the major third, and the three to five tones are the third degree of the small, which is the third degree of the third chord; The root tone of Dm, Em, and Am is a small third degree, and the three to five tones are three degrees large, which is a small three chord, while the root tone of Bdim to three tones, three tones to five tones are all small three degrees, which is a minus three chord (we will talk about it later). These seven chords are based on the natural scales of C major and are called "sequential chords". They are also the most commonly used chords in C major.
(2) Chord diagrams
F chords require the index finger to hold the first product of both the (1) and (2) strings (commonly known as the "small horizontal press"), which requires greater force of the fingers. The chord uses the little finger of the left hand, the strength of the little finger is relatively weak, plus this fingering also requires good ductility between the little finger and the ring finger, so this chord is not easy for beginners. Friends who are new to guitar are often interested in the first few days, but before long, many people flinched, and F chords and G chords are a hurdle in front of everyone.
Of course, for people with too weak fingers or female classmates in the guitar class, if they are still unable to face these two chords after several days of hard practice, it is not without "opportunistic" methods, which is:
F chords can be replaced by fmaj7, which is pronounced "F major seven", which is often used in C major to replace F, and the fingering is simpler.
As for the G chords, you can also press them with another fingering, as shown in the figure:
It must be told that the above method does not completely replace the original fingering, especially F and Fmai7, which are originally two different chords. "Changing tactics" is a stopgap measure for the beginner level. Friends must practice standard fingering well, only in this way can we be fearless in the face of more difficult techniques in the future.
(3) Master chords, genus chords and subordinate chords
In C major, the C chords show the tonality of the song, are the most stable, and it is called the "main chord"; G chords are the most supportive of the main chord, and the tendency to carry out the main chord is also the strongest, it is mostly as a semi-terminated or incomplete termination chord of the musical segment, known as "genus chord"; F chords can be performed to the main chord or to the genus chord, which is called the "subordinate chord".
(iv) Basic chord progression in C major
In C major, the most basic chord progression is:
C—G—C
C—F—G—C
The beginning and end of the song are generally with the main chord C; Genus chord G generally precedes C; The subordinate chord F always appears in the climax of the song and proceeds through the genus chord to the main chord C.
(5) C major
Careful friends will surely find that in the lessons we have learned earlier, there are often two titles at the same time, "C key" and "C major", so are they the same thing?
Let's start with the scale in C major.
Obviously, the first note of the C major scale (the main tone) and the third note (the middle note) are the major third-degree interval, so we can conclude:
The scale of the major major between the main and the midrange is the major scale, which is major.
(vi) A minor
Let's rearrange the scales in C major again:
The composition of this scale is exactly the same as in C major, but due to the different arrangements, it is certainly not the C major scale. It doesn't seem right to say that it's in A major, because it's not a major third but a minor third between the main and midranges.
Now tell you that this scale is called "a minor scale". It is arranged differently from the constituent tones of the C major scale, but since they are both based on C as 1, both A minor and C major are C key.
The interval relationship of any minor scale is exactly the same as that of a minor, and its main to midrange is a minor third.
(7) Relationship tone
C major and A minor constitute the same tone, the same key sign, but the main tone of the key is different, we call them "mutual relational key", C major is a minor relational major, a minor is C major relational minor. #音乐 #
The most popular saying is that the minor key named after the "6" tone of a major key is the relation minor key of that major key.
Friends can calculate for themselves:
The relation minor in C major is a minor minor;
The relation minor in D major is b minor;
Relational minor in E major minor;
Relational minor in F major is D minor;
.......
For ease of lookup, we list a relational key map so that the relationships are clear at a glance.
The outer ring is in major key, and the inner ring is in relation minor key in that major key.
(viii) Simple configuration of chords in C-key songs
Although both C major and A minor are C key songs, there are obvious differences:
1. Songs in major are more majestic and songs in minor are more feminine.
2. The three main chords of a song in major are built on the scale "1 4 5", while the three main chords of a song in minor are built on "6 2 3".
For example, the main chord in C major is C (with "1" as the root note); The subordinate chords are F (with "4" as the root tone) and the genus chords are G (with "5" as the root tone); The main chord in A minor is Am (with "6" as the root tone), the subordinate chord is Dm (with "2" as the root tone), and the genus chord is Em (with "3" as the root tone). #吉他谱 #
In the modality, the main, genus, and subordinate chords form the basic framework of musical harmony, known as the "positive triad chord", and the other levels of chords are called "sub-triad chords". The major triad chords in C major are C, F, G, and the minor triad chords are Am, Dm, Em; The triad chords in a minor are Am, Dm, Em, and the minor chords are C, F, G.
With the above knowledge, we can assign some simple chords to the song, taking the key as an example; 1. The beginning and end of the song in major are based on the main chord C; Songs in minor begin and end with the main chord Amo
2. The chords of major songs are mainly C, F, G, and the chords of minor songs are Mainly Am, Dm, Em (or E); If desired, some relative chords can also be used, i.e. secondary threes. chord. #吉他 #
3. The most common chord arrangement for songs in major is C-F-G-C, and the song in minor is Am-Dm-Em-Am
(ix) It belongs to the seventh chord
Let's get to know a few new chords.
The four chords on the right are all superimposed on top of the big third chord with a small third-degree interval:
The constituent tone of the chord is "1 3 5", and the upper third degree of the "5" is "7T", so the constituent tone of the C7 chord is "1 3 5 b7", and the "" sound is called the "seven tones of the chord".
The composition of the G chord is "5 7 2", "2" above the smaller third degree is "4", so the composition of the G7 chord is "5 7 2 4".
The constituent tone of the E chord is "3 #5 7", and the upper third degree of "7" is "2", so the constituent tone of the E7 chord is "3 #5 7 2".
The constituent tone of the A chord is "6 #i 3", and the upper third degree of "3" is "5", so the constituent tone of the A7 chord is "6 #1 3 5". (The number is marked red means that a dot is left on the head of the number)
(10) Skill training
(1) Left-handed independence training
At the second level, we focused on the chromatic scale practice, and your left hand skills must have improved a lot. However, with the advent of the seven chords, the little finger was used more and more frequently, and the small horizontal press at this level became a roadblock. At this time, the most important problem you have to solve is to improve the flexibility and independence of the fingers.
Below, we play in the ninth position with the following finger combination, opening the metronome as we practice, starting at a slower speed.
A:1 2 3 4 B:1 3 4 2 C: 2 1 3 4 D: 2 3 1 4
E:2 3 4 1 F: 2 4 3 1 G: 3 1 2 4 H: 3 4 1 2
I:3 4 2 1 J:4 2 3 1
Notes:
(1) 1, 2, 3 and 4 represent the left index finger, middle finger, ring finger and little finger respectively.
(2) There are 24 combinations of the four fingers of the left hand, but the above 10 are the most valuable for practice. We don't have to finish playing 10 combinations every day, we can choose three of them as the focus of the day, and the time should be no less than 15 minutes.
(3) After practicing in the ninth position, everyone can also move to the first position to practice. Because the distance between the low-handed characters is large, it is also an exercise for the spread of your fingers.
(ii) Tips for quickly changing chords
Beginners often lead to the confusion of the rhythm due to timidity and hesitation when changing chords, and the lack of proficiency is of course an important reason, and the problem of method cannot be ignored. Here are a few more tips for changing chords.
Bass Leading
The last note of the chord and the first note of the next chord must never be interrupted, which is the key to success. For example, in the progression of C-Am, the root tone of Am is an empty chord tone, so friends can temporarily ignore the complete fingering of the Am chord after playing the C chord, and the thumb of the right hand will first pop the bass of the first (5) string. This way, there is no interruption between the two chords.
Individual breaks
If you can't press all the notes in the chord at once, don't be discouraged, you can take the "individual breaking" approach:
Since the right hand plucks the strings in order, the fingers of the left hand can first press the sound to be played by the right hand, pop this tone out, and then press the next tone to be played by the right hand. In this way, the use of time difference can greatly reduce the difficulty of changing chords.
Utilize retention refers to
For example, in the case of playing Am-, both the index and middle fingers can remain motionless, just move the ring finger. Therefore, when converting, the index finger and middle finger should be used as the fulcrum, and only the ring finger should be moved.
(iii) Simple solo
Although we are learning to play the guitar and sing, it is also necessary to do some simple solo exercises. Solo not only has higher requirements for finger function, but also helps to cultivate your musical sense in an all-round way.
"Friendship Lasts Forever" is a well-known track. Play this song first in this level, and then play this song again. When playing, no matter which string the melodic sound appears on, everyone should play it with their thumbs in order to unify the timbre.

Track analysis
Chords with small horizontal presses appear in the third-level track, which is a problem for beginners. As long as the chords are smoothly changed and the F chords are played clearly, you will pass the level.
