About the Fingers
The first thing a new guitarist notices is that the tips of the left-hand fingers
can feel sore after a stretch of playing. This is particularly true if you’re playing
a steel-strung guitar, but is noticeable even with nylon strings.
Just as a trumpeter must develop his “chops,” the guitarist will develop calluses.
It may take several weeks—or even months—for these to develop. And, if you take
a break from practicing, you may lose the calluses you’ve built up.
