Inverted Fifths for Rock and Metal Guitar
The interval of an inverted fifth has the same notes as a perfect fourth. For example, the notes D and G can be seen as a perfect fourth built on D, or as a perfect fifth built on G, but with the fifth on the bottom or “in the bass”. If we play the inverted fifth on the D and G strings, it can be viewed as part of an open G chord, as seen in example #58. No matter what we call it, this interval is more harmonically complex than a simple perfect fifth but still sounds great with distortion. The riff in example #59 uses the inverted fifth interval over an open A pedal.
