The best way to learn to play the acoustic guitar is to take lessons from a qualified guitar instructor. They can teach you the proper techniques for holding and playing the guitar, as well as how to read music and play songs.
The amount of time it takes to learn to play the acoustic guitar varies from person to person. With consistent practice and dedication, most people can learn the basics of guitar playing within a few months. However, it takes years of practice to become a skilled player.
The correct way to hold an acoustic guitar is to sit with the guitar resting on your right thigh (if you are right-handed) and the body of the guitar pointing towards your left. The guitar should be supported by your left foot, and your left arm should be wrapped around the guitar’s body.
An acoustic guitar can be tuned by turning the tuning pegs on the head of the guitar. There are several tuning methods, including using an electronic tuner, tuning to a piano or another guitar, or using a phone app.
The best type of acoustic guitar for a beginner is one that is comfortable to hold and easy to play. A smaller-bodied guitar, such as a concert or a ¾-size guitar, may be easier for a beginner to handle than a larger-bodied guitar.
