What does guitar rely on to make sound
Guitar belongs to plucked instruments and is pronounced by the vibration of the strings.
The neck of the guitar has metal threads, and the left hand holds the back of the neck with the thumb to fix the position of the hand. The index finger, middle finger, ring finger, and little finger press the strings. By pressing specific strings between different pieces of piano with the fingers of the left hand, the strings are tightly in contact with the metal wire, which can change the length of the string vibration. At the same time, using the thumb, index finger, middle finger, and ring finger of the right hand to pluck the strings that need to be sounded, the strings can produce different heights of sound. Of course, the plucking of the strings on the right hand can also be done using tools such as paddles.
When a string vibrates, it undergoes a change in tension along the direction of the string. When the tension becomes tight, downward pressure is generated on the panel through the bridge, and upward tension is generated by pulling the panel through the code. Therefore, the panel before the bridge will move downward, and the panel after the code will move upward. When the tension is restored, the panel state is restored, resulting in continuous up and down twisting vibrations.
It is not difficult to see from the above vibration transmission principle that making the strings vibrate in the direction perpendicular to the panel can increase the pressure and tension obtained by the panel, and make the panel vibrate fully. This is the key to producing good sound for the guitar.
