The answer is basically - no. But we are going to cover it anyways. The last chord in the Key of G.
F# Diminished. F# A C. Memorize it? Sure!
But we almost never use it, you probably wont either.
I’ll tell you how you can use it, and then!!!! I’ll suggest a cool alternative TO it that we can use and that is frequently used as an “outside” chord IN G!
How to use it: This chord can be used as a V chord. the D to go straight to G. It resolves nicely. Sounds weird, but resolves nicely.
This concludes our key of G!
Now how to use something I consider more useful?
Instead of the viio (Roman numeral for the last chord diminished). let’s kick that back a half step more and make it a major chord, the “Flat 7 chord in G”. the bVII - F major. It too works now with the rest of the chords in G
In fact without it, Freebird doesnt exist!
G D Em F C D - Intro to Freebird
I V vi bVII IV V.
When making a bVII in any key take the Letter of that Key, pop it back a letter before, and make it a major chord.
so if my Key is G
The alphabet letter just before G is F
F major is my bVII and sounds great going to G!
Hope this made sense! Would love your thoughts and feedback!
