During every guitar lesson my teacher says: "play it again, but this time without sqeaks and buzzes! Become aware of your sqeaks, don't accept strings noises while studying. Go back and find a way to play cleanly. If you still can't, I will help you with different fingering or additional exercises to overcome the sqeaks."

"While you try to master classical guitar, prepare for a slave's life: the guitar will forever be your master and you its slave".
