Guitar Tutorial—Chromatic Scale

“The invention of the twelve equal temperaments introduced the establishment of the chromatic scale. The chromatic scale divides an octave into twelve identical semitones or semitones Each semitone is equivalent to a fret on the guitar. The ratio between every two notes is 1.059. A whole tone is two semitones, which is the distance between the two frets. The chromatic scale is very important. Various other scales were developed from the chromatic scale. With the equal temperament, musicians could not only create strings but also play any of the twelve keys without the hassle of transposing. To choose a key is to choose the first whole tone among the twelve semitones of an octave, and then build your scale according to the given interval method, using the whole tone and semitone method described above in 1722. In 2000, Bach showed the universality of the application of twelve equal temperaments in his "Well-Tempered Clavier". This novel piece uses one of the twelve semitones as a loyal tone one after another. Change the key until all possible keys are used

"Now, let's sit back and take a good look, kid. First of all, we know that there are octaves in human hearing. Next, we divide an octave into twelve equal parts called semitones, and two semitones make a whole tone. Starting from the diatonic scale, any major scale in any key will have the following intervals.

"The setting of the piano keyboard is that if you play the C major scale, you only need to use the white keys. And the C key is also one of the seven major scales named after letters. Basics. One weird thing is why they didn't center the name on the letter A; anyway, they didn't do that. So, what you get is represented by the following diagram:

Originally. At that time, everything was based on the four hundred and forty A note. Using the equal temperament, we can find the C note below the A note. This C note is called middle C. The C sound in the center is named alphabetically, and each white key is named one of the letters A to G. We all know, and can see from the keyboard, that the major scale is not a set of keys. Therefore, in order to make up for this shortcoming, there are five black keys in each octave, which are used to play the transitional semitones in the five whole-tone scale. The result is that the E key and the F key, and the B key and the C key are pressed directly together. Now let's expand our horizons and take a look at all the octaves on the piano.

Finally. The common music notation system uses an alphabetical note system, using the key of C as the basis. The notation method of the staff is to use each line or between two lines to represent a series of major scale notes. The way to change a semitone is to add a sharp or flat on the line or space of the note to be changed. This is the method used in music to record works in other keys, that is, methods other than using the major scale. Here are the two most commonly used staves, which indicate all the scales in the key of C. Middle C is originally the central boundary we use to divide the treble part and the bass part, but here it falls on the lower line of the treble clef. When we play the piano, the notes using the treble clef are usually played with the right hand; the notes using the bass clef are played with the left hand.

The old man took out a key from his pocket. , walked to the front door of the house. He opened the door and walked in, and the boy followed him curiously. "Uncle, you must have many guitars here," the boy said while looking at the house with wide eyes. /p>

"What can I say, kid, I can only tell you that the piano and speakers are in another house. "

Inside the house from top to bottom, on the walls and on the floor, there were all kinds of imaginable musical instruments and their accessories. Regarding this, the boy couldn't help but be curious about the old man. How is all this happening? What’s going on? How could an old man living by the railroad have such a house full of collections? “This place really looks like a musical instrument store, old man. "

After hearing this, the old man smiled slightly and said: "It's the music room, kid, just use your terms. Now, don't be intimidated by this rich variety of instruments.

Remember, it's quite difficult to play all of these instruments without putting in a lot of effort. Don't think about whether I'm poor or rich, kid. You just need to sit in a chair for a while, listen to me play the blues, and think about the space in which we live. "

The old man sat down diagonally in the corner of the room, and then played an old and slow blues. It seemed as if the melody had been going on, and the old man played it as accurately as tuning a radio. . The boy slowly fell into sleep.
