In this video lesson, Instructor Pete Pidgeon talks about Octaves. In music theory, playing the first and eighth note of a major scale on the guitar will produce an octave.
Video Transcript: PETE PIDGEON: "Here we'll discuss the octave. An octave is the same thing as eight. It's where you play through the major scale one, two, three, four, five, six, seven, eight. When you get that half step which brings you back to the beginning again where you get the same letter name note that you started with. So for example, here we're in the key of G we're starting on a G note going up in a G major scale and when you get to that eight note you're back on a G again. Now there's a couple ways you could do this, you could play the octave this way. Same interval shape as the fifth but you move down one string and here we hit the B string, stretch it out by one. Here we crossed over the B string so stretch it out by one. Now at this point we can actually skip two strings and have that interval shape in a different area. So for example if this was our first note, instead of playing the octave here, we could take this note back one, two, three, four, five frets and play it on the next string. So you could also do an interval shape down two strings back three frets or from the A string we got to move it up. From the D string we've crossed over the B string so we also have to move it up."
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.
