Hi. This is Hub Guitar.

Let's talk about learning the intervals on the guitar fretboard.

A lot of guitar players never take this step, and it's a shame because this is really key to understanding how the guitar works.

You probably already know what an interval is. It's the measurable distance between any two notes. For instance, this is one interval, and that is another interval. You also probably know of a few intervals already. You have your octave, which is a note of the same name that is higher up. You've also heard of half-steps, consisting of one fret, which is really the interval called a minor second. And whole-steps, consisting of two frets, would be the interval called a major second.

But actually, every distance between any two points has a specific name and a consistent relationship on the guitar that you can learn. If you can learn how to play and recognize all of them, it will really help unlock the fretboard.

You can do this between any two points at all, so you can just take this note, and this note, and ask yourself what the interval is. you can also give each interval a different name sometimes depending on whether you're thinking in terms of the bottom one going up, like is it a G going to C, or it's a C going down to G. For instance, the half-step here can be thought of as a minor-second if you're going up a half-step, but if you're going down a half-step it can be thought of as a major-seventh going down. because this would be the major seventh above, this would be the major seventh below. For now, we are just gonna think of them as a low note, and what the higher note is in relationship to the low note.

For now, we're gonna start just the fifth string and sixth strings.

So we'll play C on the fifth string and figure out what all the intervals in this neighbourhood are. So here is a C on the fifth string. I want to know that in relation to this note, what're all these notes in this neighbourhood. The best thing to do is to play a major scales and start there. For instance from C to E is a major third. From C to F is a perfect fourth. From C to G is a perfect fifth and so on. So we want to look at all of these other notes around this neighbourhood and then figure out what interval they would be. The C was root.

We can also do it at the VIIIth fret, and we'll have similar results.

This is very very useful for understanding chords, scales and arpeggios. In fact, when you get good enough at this, you can play a lot of patterns in real time just by using your head. Even if you haven't memorized the pattern, you can sort of calculate it if you can think quickly enough. And that's a powerful tool to have.
