In lesson 4, we looked at the important role that third interval notes play in: building chords and making them either major or minor creating harmony if you want to play them alongside your melody notes. In this lesson you'll learn how to find third interval notes quickly anywhere on the fretboard. We've already looked at how the guitar is an instrument tuned around intervals of perfect fourths and major thirds. You've also learned that the perfect fourth interval note is usually directly below your root note. So, if I play the note G on the E string, I know that the fretted note below it is going to be the perfect fourth interval (the C note): Let’s just check if that's the case and refresh our memories. Well, the fretted note on the fifth string is the note C. So there should be an interval of a perfect fourth between G and C: Tonic is G Flat 2nd is G# Second is A Flat third is A# Major third is B Perfect fourth is C If I know that the strings are tuned in interva
