Guitar Music Theory Knowledge Explained 10

Don't rush to play the tunes, learn about music theory, practice the scales in each position, and have some basic finger exercises. For example, practice the coordination of the left and right hands by climbing the lattice (the gesture method should be correct).

If you are a beginner, take a look at Liu Chuan's book that seems to be called "June Guitar Pass", take a look at the ** tutorial, and finally play with others to learn. The road is long, but it's fun. The main and most basic thing is to be interested in it and stick to it.

1. tone: It is a physical phenomenon. When an object vibrates, sound waves are generated, which are transmitted through the air to the eardrum, and the reflection through the brain is perceived as sound.

The sound that people can hear is about 16-20,000 vibrations per second, and the sound (excluding sound) used in ** is generally limited to the range of 27-4100 vibrations per second. The pitch, intensity, length, and timbre of the sound depend on the vibration of the object.

2. Tone-color: refers to the sensory characteristics of sound. The vibration of the articulatory body is composed of a variety of harmonics, including fundamental and overtones, and the timbre is determined by the number of overtones and the relative strength between them.

People's ability to distinguish timbre is innate, and the timbre of ** is divided into human vocal timbre and instrumental timbre. The human voice is divided into high, medium and low tones, and is divided into men and women; The instrumental timbre is mainly divided into string instruments and wind instruments, and the timbre of various percussion instruments is different.

3. Resonance: Resonance refers to a vibration. When one articulating body vibrates, it causes other objects to vibrate and make a sound, creating a resonance.

4. Fundamental tone: The lowest frequency sound emitted by the object when it vibrates is the fundamental tone, and the rest is overtones. The pitch is determined by the pitch.

5. Harmonic overtone: In addition to the lowest tone produced by the overall vibration of the articulation body, which is the fundamental tone, the other 4 parts are also vibrated at the same time, which is the overtone. The combination of overtones determines a particular timbre and gives a clear sense of the loudness of the base tone.

Musical instruments and all sounds in nature have overtones.

Basic music theory knowledge of the guitar; Basic music theory knowledge and notation methods for guitars; The most commonly used in folk guitars are sheet music and six-line staff.

Classical guitars use staves.; A phonetic name is the name of a sound, and its pronunciation is the roll call of that sound. This is the pitch of C major.

Add a small dot above the base symbol to indicate that the tone is raised by one note. Add a small dot below the base symbol to lower the tone by one note. By analogy, adding two dots means raising two groups or lowering two groups.

The distance between two tones is called an interval and is measured in degrees. 1-1 is one degree, 1-2 is the second degree, and so on 1-5 is the fifth degree, 1-6 is the sixth degree, and 1-7 is the seventh degree. The division of tones within an octave into twelve tones of equal frequency is called the twelve equal temperament.

A semitone is the smallest unit of twelve equal temperaments, and two semitones form a whole tone. Except for 3-4 and 7 to treble 1 which are semitones, the others are whole tone relations. There are also several diacritical marks as follows:

The rising sign indicates that the original note is raised by a semitone; The b-flat sign indicates that the original tone is lowered by a semitone; The x-rising mark indicates that the original note is raised by two semitones; The BB flat mark indicates that the original note is lowered by two and a half; The reduction mark indicates that the original sound has been restored.

If the note of the same measure does not touch the reduction mark, it will always be the same as the original raised or descended note. That is to say, the diacritical mark is valid in one measure, and it does not work in the next measure, and the diacritical mark that appears in the measure is called a temporary diacritical mark, and some after the treble clef are called key signatures.

Duration of the tone: The short horizontal line added after the tone is called the time line. Each additional line indicates the added time value of one beat.
