How long does it take for your fingers to stretch for guitar?
Developing calluses on your fingertips can relieve a lot of the initial pain of learning to play guitar. On average, it takes 2 to 4 weeks for calluses to fully form. But callus formation differs from person to person depending on: how often you practice or play.
Can you stretch your fingers?
Finger Stretch
Place your hand palm-down on a table or other flat surface. Gently straighten your fingers as flat as you can against the surface without forcing your joints. Hold for 30 to 60 seconds and then release. Repeat at least four times with each hand.
