Watch the Minor Sea online guitar lesson by Jeff McErlain from Essentials: Advanced Blues Rhythm
Here we have a basic blues in the key of C minor. A minor blues is just like a standard blues, except each of the three chords are minor. There are definitely variations upon that, but this is the most basic form of a minor blues.
We're going to take a look at some cool triad inversions on this one, which I think will be very helpful. If you are anything like I was, I was always at a loss as to what to play on open sounding blues like this one. I cannot stress enough the importance of learning your triads as both a lead and rhythm guitarist, and fortunately the two of those overlap quite nicely.
