Matthew McAllister gives a lesson regarding string squeaks and buzz on guitar. This comes via the excellent Siccas Guitars and their fantastic YouTube channel. Siccas always have their visitors play on in-shop guitars, here a Armin Hanika 58 CC 2016. Matthew is a fantastic performer and down to earth guy. Above all, Matthew is always super musical so I love his well-rounded lessons. If you’re looking for a technique book you can check out my review of classical guitar technique and exercise books.
String squeaks are part of the instrument but can be greatly reduced and often eliminated completely with practicing and care. Great video angles and descriptions of finger releases. Take care to put his two-stage release into practice. You need to make it part of your muscle memory and your active listening. He demonstrates using the allegro from Barrios’ La Cathedral.
