In this video lesson, Instructor Pete Pidgeon talks about Intervals. In music theory, taking the second note of a major scale and moving it up an octave can be referred to as a second plus an octave, or a ninth.
Video Transcript: PETE PIDGEON: "Now you might ask what happens and what would you call and interval that's larger than an octave which would be the eight or essentially where you would start over again at one. Let's take a look at that. Let's use the major scale now from the middle finger. One, two, three, four, five, six, seven, eight. Now earlier when I played this shape, I went to this note because I went through two octaves. Now this note instead of being nine would actually be if you started over at one again. That could also be two it's an octave above the second note in the lower octave. Now you would probably call that either an interval of a ninth which would be acceptable. Again you wouldn't call this and eighth, you'd call that an octave but you could call this an interval of a ninth which would imply that you’re going a second plus an octave. Now you could also call that a second plus an octave. That's another common way of referring to it but essentially you're playing the major scale. You're hitting the second note and you're going an octave above that second note. So it would be the first note up an octave plus a second and you can do that all the way up the neck going to fourths, fifths and keep counting up tenths, elevenths, twelfth, thirteen's, fourteens. We'll refer to it as octave plus the interval an octave below."
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.
