In this video I’m breaking down music theory made easy with an intro to intervals on guitar. An interval is simply the distance between two notes, and if you already know “half steps” and “whole steps,” you’re already on your way. I walk you through the first 12 intervals from the root up to the octave—minor 2nd, major 2nd, minor 3rd, major 3rd, perfect 4th, tritone, perfect 5th, minor 6th, major 6th, minor 7th, major 7th, and the perfect octave—using a super clear fretboard example so you can actually see and hear the spacing. Then I show you why this matters for real-world playing, especially if you’re trying to learn songs by ear (which is huge for R&B). Once you can recognize the sound of key intervals, chord changes start to make way more sense. I demonstrate how major chords are built from a major 3rd + perfect 5th, and how minor chords swap that major 3rd for a minor 3rd to get that darker sound. I also show how knowing intervals helps you name “jazzy” chord shapes you might not recognize, and I share an ear training app I used (Perfect Ear) plus what scales I recommend for R&B: major, natural minor, and major/minor pentatonic.
