I played classical guitar for years without paying attention to
the fingernails of my right hand. I just used the tips of my fingers
to play. It was ok and sounded good but When I started growing my
nails and caring for them a whole new world of sound possibility
opened up for me. If you are serious about classical guitar you
really should grow and maintain the fingernails of your right hand.
The illustration at right shows how your nails should be sculpted
for best effect.
line 1 shows the nail rounded and centered. This is incorrect.
You should file the nail so it is longer on one side (either the
left or the right depending on what feels better for you). This
enables the nail to slide off the string creating a smoother action.
Lines 2 and 3 show this.
Right Hand Nail Length
The illustration at right shows approximate nail length. If you
hold your finger out the nail should be approximately as long as
the end of the finger tip. Picture a vertical line drawn from the
nail. It should be even with the tip of the finger.
This is just my recommendation. Some guitarists prefer to grow
their nails much longer.
A Note: There are commercial nail hardeners that you can apply
to your nails. I have used these with some success. They tend to
crack and split quickly for me.
The Nails of the left hand should be trimmed short and maintained
short.
When playng guitar develop a sensitivity for your nails and you
will develop nail length and nail care that is right for you.
