One of the most fundamental, yet still difficult, skill for beginning guitarists is figuring out how to position their fingers. Many beginners feel like their fingers hurt, or they struggle to get a solid, ringing note when they hold notes or chords. But with a few simple tricks and some patience, you can improve you playing with proper finger positioning.
Put your index finger on your left hand on the first fret of the B string. Place your middle finger on the second fret of the D string, and your ring finger on the third fret of the A string. Press firmly with the tips of your fingers and be sure not to accidentally mute any other strings.
