Chords are a very important point of knowledge for ukulele. Whether you play or finger, you can't do without chords. Chords are also a very important concept in music theory. In order to understand the chords, understand the application of chords on ukulele, and understand the various concepts on the score, it is necessary to explain the basics of music theory. The knowledge of music theory is very complicated. This article only covers the necessary concepts, almost all dry goods. More in-depth knowledge of music will be developed separately in the future. The pitch of a tone is determined by the frequency. Assuming that the pitch of a note is do, then its pitch is twice as high as an octave. That is to say, the frequency of a sound is doubled, and it is one octave higher. The interval between the two dos is called an octave. So octaves can be circulated, with a do in each octave, and the frequency of these dos has a multiple of 2. An octave can be divided equally into 12 equal parts. Each halved interval is called a semitone, and the interval of two semitones is called a full tone. Starting with do, the scales are arranged in a semi-full half, forming a Do Re Mi Fa Sol La Ti Do, eight sounds, which can also be represented by the number 12345671. It can be seen that the intervals between 1 and 2, 2 and 3, 4 and 5, 5 and 6, 6 and 7 are all full, with an intermediate tone between them, between 1 and 2. The pitch is one semitone higher than 1 and one semitone lower than 2. This sound can be called as 1 and is marked as #1. It can also be called drop 2, marked as b2, and so on. These twelve tones are 1, respectively. #1(b2), 2, #2(b3), 3, 4, #4(b5), 5, #5(b6), 6, #6(b7), 7 Why 12 cannot be used separately The two numbers are represented, but are represented by 7 numbers and the deformation of these numbers? In fact, this can also be done, but the first time people discovered these seven sounds, they first named the seven sounds. Later, after discovering the law of the twelve average law, the remaining sounds were followed. The named sound is transformed.
The most common and half-tone relationship is most commonly used. The music composed of these sounds sounds broad and broad, and is called the major scale. In fact, there are many kinds of intervals, and they also have their own characteristics. They are arranged in a semi-quantitative relationship. They are called minor scales, and the listening is soft and faint. It is used more in popular music. The rest of the arrangement is not introduced. Do Re Mi Fa Sol La Ti, also known as 1234567, is called a roll name. They do not contain absolute pitch. This set of scales only represents the interval relationship between frequencies. 1 can be any pitch. In order to determine the pitch, we can use CDEFGAB to indicate that they also obey the interval relationship of half-quantity, and their pitch is fixed. For example, the frequency 440Hz is internationally recognized as a standard sound, and its sound name It is A, and these letters representing the pitch are called sound names. As mentioned above, the roll name is variable and the phonetic name is immutable. If you think of C as 1, that is, use C as the main sound and arrange it according to the major scale, then the obtained scale is called the C major scale. If you arrange it according to the minor scale, the obtained scale is called the C minor scale, and so on. A series of scales such as D major, D minor, E major, E minor, etc. can be introduced. If a song can be sung in D major, but another person may not be so high, he will drop a tone to sing, he can drop to C major to sing. After the transposition, the title of the song is actually unchanged. For example, the original D is the main voice, and the vocal singer is changed to C. When the chorus is changed to C, the pitch of D in the original song falls to the height of C, but Still sing to do 1. The tone change does not affect the direction of the melody, so it is not a particularly important thing for the vocal to be at that height. A sound composed of a plurality of sounds according to a certain rule is called a harmony, and a harmony composed of three or more sounds constitutes a chord, that is, the chord has at least three sounds. The pitch relationship between the two tones. Expressed in degrees. Taking the notation as an example, from 1 to 1, or from 2 to 2 is one degree, from 1 to 3 or 2 to 4 are all three degrees, and from 1 to 5 is five degrees. In this way, five degrees are superimposed on two degrees. Starting with a single tone, adding a third and a fifth to form the basic triad, and the starting tone is called the chord root. The third degree means that the relationship between the three tones is a full-tone relationship, that is, there are two full-tones, that is, the third degree. The third degree means that the three tones are composed of one semitone and one full tone. Use the third degree to superimpose the third degree to get the major chord, or use the small third degree to superimpose the major third to get the minor chord. For example, C major chords are composed of C, E, and G. They can be abbreviated as C chords or C. C minor chords are composed of C, bE, G, which can be abbreviated as Cm chords, or Cm. . Chords are also composed of four or more tones, and there are other variants that are not covered here. The chords are superimposed from the root to the third degree. At each level of the major, a chord composed of the tones in the major scale can be constructed. These chords are called the major chords or the chords of the majors. In the same way, minors can also form their own chords or chords. The chord composed of the major scale of C as the main tone is called the inner chord or the chord of the C major, and the chord composed of the minor scale of the C main sound is called the inner chord or the chord of the C minor. And so on. Taking C major chords as an example, the C chords of C majors are C Dm Em FG Am Bdim. These chords are arranged in order, and their order relationship can be represented by series. The series is represented by Roman numerals or Arabic numerals 1234567. , C is a 1st chord in C major, Dm is a 2nd chord, and so on.
C major and G major are the two most commonly used tones. Not all chords are commonly used in these two tones. For example, Bdim is rarely used in C major, and Bdim is often replaced by G7 chords.
The following are the common chords in the various ukuleles.
