In this video lesson, Instructor Pete Pidgeon talks about Perfect 4th Intervals. The distance between the first note and the fourth note , within a major scale, on guitar is referred to as a perfect fourth.
Video Transcript: PETE PIDGEON: "As we just discussed the fourth note of a major scale in thus the distance from the first note of a major scale to the fourth note of a major scale you would refer to that interval as a "perfect fourth" rather than a "major fourth". Let's take a look at that on the guitar if we start from the "G" to the second note of the major scale, third note to the fourth note. The distance between the first note and the fourth note would be called a "perfect fourth". Now notice that there is no diminished fourth or minor fourth because this note is the same as the third note for the major scale since there's only a half step between the third note and the fourth note of a major scale. You would almost always refer to this note as a third and almost never refer to it as a diminished fourth. So instead we've just got one, two, three, four and then when you get to five you have a diminished five but let's take a look at this interval shape. You've got down one string same fret. It's always going to be the shape 4/4, perfect fourth, except when you get to that B string. You got to raise that up by one fret."
In this course, Guitar Instructor Pete Pidgeon gives 16 video lessons on Guitar Music Theory. We will explain the intricacies involved with guitar intervals within music theory. Pidgeon will begin by explaining what music intervals are and their relation to the neck of the guitar. He'll then begin explaining how to find and create various intervals using the neck of the guitar. Pidgeon will explain the minor second and major second intervals, the difference between perfect and diminished notes, as well as what octaves are and how to locate them. These intervals are great for understanding notation and building upon the foundation of guitar music theory. Watch these videos and begin learning music theory for guitar today.
