Playing classical guitar requires good technique, as it is an instrument that does not pardon any imperfections. In particular there are some mistakes that should be avoided. Here’s a video that explains the five mistakes to avoid when you play the classical guitar:
-Poor alignment: Playing with inefficient or potentially harmful angles in the wrists.
-Bracing: Touching the top of the guitar with the right hand pinky or ring and pinky.
-Splayed fingers: Right hand fingers are widely separated from each other
-Bouncing: Pulling the fingers and hand away from the strings on every note.
-Bicycling: Hooking the strings with the right hand fingers, snagging the strings (extremely common)
