Hi Everyone!
In this lesson, we'll turn your plain old triads into 7th chords! On top of that, you'll learn about 7th chords in a key, and start to create chord progressions with more depth and sophistication. Check out the attached PDF for helpful homework and chord charts.
If you’re not familiar with Major Scales, Minor Scales, Intervals, the Circle of Fifths, and Triads - you should watch Music Theory for Guitar I first!

For the same reason the IV chord is a Major 7th chord and not a Dominant 7th chord: a half diminished fits diatonically in a major key and a fully diminished chord does not.
