I play classical guitar a lot, with my fingernails. My sister is an excellent classical guitarist, over 2 years of training from an experienced player. Most of my musician friends who have had over 5 years of "normal" "guitar lessons" (i.e. power chords and rock music, some jazz) envy her playing. I have learned much from her! The most important thing I learned from her was how to go about cutting/shaping my nails. Her instructor mentioned professional players taking years to perfect the technique of getting their nails 'just right' on both hands for playing. As of right now, my fretting hand has nails very short, enough to "click" on a desk barely, but not measureable. My picking hands nails are about 2mm to 3mm long, now... my friends seem to think this look is insane, one hand long fingernails one short. I cant convince them this helps me play the songs they seemed so amazed to see someone play, i.e. Beethoven - Fur Elise (these people listen to punk and metal and are enthralled by this song played on a guitar!) The short nails do not hinder my fretting (longer ones do while chording hard chords) and the Long nails help me play very controlled, and are filed so they are strong enough to play a bass. Does anyone else cut their finger nails in a fasion which was intentionally done to play music? Have you heard any of this as being a technique to help playing? Do you have any tips?
