What does your left hand do when you play the guitar?

Playing guitar with your left hand means pressing scales or chords.

By pressing the string, the length of the vibrating part of the string is changed, and the frequency of its vibration is changed, thus changing the pitch. The shorter the vibrating part, the higher the sound (that is, the sharper it is). Conversely, the longer the vibrating part, the deeper the sound.

1, when pressing the string with the left hand, the knuckles of each finger should bend naturally, the first knuckle of the finger should be perpendicular to the fingerboard as far as possible, and press the string with the tip of the fingertip of the finger.

2. Straighten your thumb and hold the midline behind your neck with your fingertips as the support point of your left hand. The joints of index finger, middle finger, ring finger and little finger should be able to move and stretch flexibly.

3. Don't stick your left palm and tiger's mouth to your neck, and don't pinch your neck by "grasping" because it will reduce the flexibility of your left hand. The center of gravity of the left finger is placed on the thumb and middle finger, so that the two fingers hold the neck back and forth relatively.

Extended data

There are four main ways to play the guitar:

One is to play with your fingers, but your nails are easy to damage. Therefore, people often use fake nails or apply nail polish that can strengthen their nails.

The second is to pluck the strings with elastic pieces (plucked pieces) and make music with a * * * sound box.

The third is playing with a metal round tube (sliding guitar).

The fourth, less popular, is to play with finger covers that can be worn on your fingers.
