Blog Guitar Technique March 30, 2016 Share Tweet Share A pinch harmonic (or pick harmonic, squealy harmonic or squelch harmonic – call it what you want!) is a guitar technique that literally makes your guitar scream. In my opinion it’s one of the coolest techniques you can incorporate into your playing. It’s a very cool expression technique. To generate a pinch harmonic you strike the string with the pick and a part of the flesh of the thumb. What is technically happening is the thumb is cancelling out the note struck by the pick and only allowing the harmonic overtone to sound. Get started with pinch harmonics by doing this: Crank up the gain – you need some distortion Choose one note to practice on – 7th fret on the G string (3rd string) is perfect Pick as close to the bridge pickup as possible without picking over the top of it Use the bridge pickup Think of the pinch harmonic as the icing on the cake. Like the high pitched scream the singer does when he just can’t hold his emotions in any longer.
