Hold the guitar with your left hand. The side of your thumb should be right behind (close to touching) the fret wire on the back of the neck.
A guitar is a beautiful instrument, both literally and figuratively. While it takes the touch of an artist to make music with this stringed wonder, it also takes tender care and attention to keep your guitar in top condition for years to come.
A guitar can be strung with different gauges of strings to vary the pitch and playability. A commonly used set is the “D’Addario EJ16 Phosphor Bronze Light” gauge .012-.053 for acoustic guitars.
