Watch the False Fingerings online guitar lesson by Shane Theriot from Solo Mojo
In saxophone terminology, players sometimes use alternative fingerings to create different textures of sound, or different tone qualities, on the same note. This is commonly referred to as "false fingering", or as I call it "unison notes". This can create a cool repetitive "pulse" sound even though it's actuality the same note being played repeatedly. This sound has become a huge part of my playing. Once again, it's from listening to a lot of sax players, particularly Michael Brecker.
