Watch the 3rds/4ths online guitar lesson by Charles Chapman from Interval Insights
The combining of doublestop 3rds and 4ths in rhythm parts and solos is often identified with Jimi Hendrix, who made especially great use of them in ballads like "Castles Made of Sand" and "Wind Cries Mary." Hendrix was always quick to point out that he picked up the hammered 3rds and 4ths idea from Curtis Mayfield.
In keeping, and in respect, our performance aimed for a decidedly R&B vibe. Compare the VIDEO1 clip here to the VIDEO1 clip for 4ths - which uses the same backing track and feel - to see how the subtle harmonic differences between 4ths and 3rds compliment one another.
