As a very popular instrument, guitar has always been concerned and loved by people. Its tone is soft, beautiful and romantic, which can bring endless sensory enjoyment to people.
Learning guitar requires a lot of effort and patience. However, if you want to learn the guitar well, you not only need to learn how to play it, you also need to understand it deeply!
The guitar is a plucked instrument that first originated in Spain. The common guitar has six strings, and in terms of construction and playing style, guitars can be broadly divided into three categories: classical guitar, acoustic guitar and electric guitar.
The Steel-string Acoustic Guitar is a modern form of guitar, derived from the classical guitar, but it uses Steel strings to produce a louder sound. In Europe and the United States, it is usually called Acoustic Guitar, our common acoustic guitar has the following four types of guitar:
The construction of acoustic guitar
We have known various types of guitar, let's understand the structure of acoustic guitar: acoustic guitar, can be roughly divided into three parts: head, neck and body.
The head includes a string knob and a string pillow. String buttons, also known as "winders," are used to hold and adjust the strings. The string pillow is used to hold the strings between the neck and the head. In addition, the brand of the guitar is usually marked on the guitar head.
The neck is the "handle" of the guitar, including the quality column, fingerboard, character, and taste mark. The column is an important part to determine the pitch, and the acoustic guitar generally has 20 (or 21) columns. The fingerboard is a section of the front of the neck where the left hand plays, and each string has a corresponding plate, through which different pitches are produced.
The character is located on the fingerboard between the product column and the product column (also including the upper string pillow and the product column), referred to as the product. The grade mark is mounted on the fingerboard and the section above the neck to record the position of the character, which can help us find the position quickly.
The body of the acoustic guitar is mainly composed of three parts, they are the panel, the side panel and the back. A good solid panel (rather than sandwich or plywood) is the most important factor affecting the sound of the guitar, while a good back and side panels also contribute to a good sound.
The vocalism principle of guitar
Now that you know the structure of a acoustic guitar, let's talk about a little bit of "hardcore" -- what is the principle of guitar sound?
Guitar is a simple plucked instrument, that is, sound by the strings, but the simple string sound is relatively small, for example, we use our hands to open a rubber band, and then plucked the rubber band, can also sound, but the sound is not big.
The guitar case plays a resonance role, that is, the sound is gathered out, for example, our mouth speaks to a cup, it will be emitted back from the cup, and the cup plays a gathering sound role.
So the sound principle of the guitar is simply that the fingers pluck the strings, the vibration generated by the guitar bridge and chord pillow is transmitted to the guitar panel, the vibration of the guitar panel squeezes the air in the case, so that the air vibration produces mechanical waves, the sound source vibration drives the air vibration, and then spreads out through the air, and finally into our ears.
After reading the above, you must have a preliminary understanding of the acoustic guitar! You see, learning the guitar is not only learning music, but also learning some physical knowledge.
In fact, exploring the mystery of the guitar is a very meaningful journey, through this journey, children can not only understand the true meaning of music and art, but also can constantly learn new knowledge. Let's continue to explore the infinite possibilities of guitar and feel the unique charm of music!
