Watch the Golpe online guitar lesson by TrueFire from Play Acoustic Guitar 8: Advanced Techniques
Golpe - Technique #30 is a video guitar lesson presented by Muriel Anderson and is sourced from 50 Right-Hand Techniques You Must Know.
Of the many flamenco techniques, I thought it would be good to briefly mention the "golpe" which means "hit" in Spanish.
This provides that signature percussive effect that sounds like the feet of the dancer in flamenco music. There are examples of this and other flamenco techniques on Tierra Negra's New World Flamenco DVD by TrueFire.
