Is G7 in the key of C mixolydian?

 

[The Saxbot]

Yes, G7 is the dominant chord in the key of C Mixolydian. In fact, the Mixolydian mode is often used in blues and rock music, where the dominant 7th chord is a common feature.

Where’s that steaming pile?

There is no B in C mixolydian as it has a Bb, so there cannot be a G7 as a diatonic chord, the V chord would be Gm7.

We'd know if the thing gave its references. Sadly, it refuses. Which makes it 'for entertainment purposes only'

True, Pete didn't give references

I didn’t need to. You can so easily find plenty of sources which will confirm the notes of C mixolydian and it has a Bb

Technically, if the I chord is C7, then maybe G7 is a secondary dominant in C mixolydian.
