La imagen anterior está sacada de un lección de Denis Warren sobre la teoría y práctica de los armónicos en la guitarra:
Achieving the control and understanding of guitar harmonics is the way to increase the range of the instrument, playing notes that go beyond the fretboard. It is also a way to include some singular effects in your phrasing or riffs, bringing expression and individuality.
In this lesson we are going to understand what harmonics are, get to know the different types and their location on the fretboard of the guitar, and how to play them.
