Podcast Episode 15: Key Changes, Borrowed Chords and Circle of Fifths

In an earlier guitar theory podcast episode you learned about chord progressions and how to play by numbers. Although a great approach to many songs, you may have realized that not all of them fit into this system of numbered barre chord patterns. In this free guitar lesson you are going to learn why. Here you will look at several related topics including: modulation, key changes, modal interchange, borrowed chords, and the circle of fifths, also known as the circle of fourths. This information comes from the book Fretboard Theory Volume II Chapter 4. https://www.guitarmusictheory.com/fretboard-theory/fretboard-theory-volume-ii/

Properly identifying key changes will help you better understand the music you listen to and play. If you are a composer or songwriter, then you will like the variety that key changes offer. Lead guitarists will know when to change their scale patterns for solos as the music modulates from one key to another.

In This Podcast Episode:

1. Modulations

2. Modal interchanges and borrowed chords

3. Circle of fifths and fourths

4. Blues changes

    Really nice to see you figured out changing mixolydian scales for country/jazz style. Material for Fretboard Theory III, A triology now that would be nice to sell as a triology pack in hard copy. Hmm… I wonder what topics could be in volume III!

    Brilliant. Thank you so much for bringing it into focus. Though I’m nowhere near the level to implement a lot of the theory, it was fascinating to understand the genius that goes into why good music sounds the way it does. Now I’ve got lots of work ahead. Scales! Scales and more scales- and how and when to mix ‘n match 🙂

    It is quite amazing that you can get across these concepts clearly and effectively without resort to visual aids. Another great lesson!
