If you ever wondered where the Western in the genre Country and Western comes from this will show you and its a lot of fun. Its jazzy. I learned a lot from this and you will too. Cowboy chords will do nicely to start too! All you need is some basic technique as in a few simple open chords positions prior to diving in, like C7th in the first position.
Now I didn't know this but western sounds almost nothing like country.
Western is jazzy - the little I have heard anyway - but its not Miles Davis/Coltrane type jazz it has a more simpler more natural structure and in this, three piece harmonization.
An upright bass, a fiddle and Mike Dowling playing a real fine looking D'angelcio arch top. Almost like a Gibson ES 175. Want me one!
Warming up to what this approach is all about is this whole rhythm technique using the 4 thickest string(s) set of those four that are closer to your face - the counter intuitive so called bottom set.
So called because guitar strings are lower in pitch the fatter they are and have more bottom. There is a whole other set of chord voicings using the top three/four thinnest strings that you should also know - same notes just different voicings.
Do you hear voicings? Well you should! But do you have what it takes to be a voice leader? You never know 'till you try! This is the antithesis of three chord rock. Its real friendly and the pace is manageable too.
Freddie Greene is a famous guitar player who played with Duke Ellington's Big band. He developed a style - and this is before amplification - that was loud enough to be heard by the other musicians and Freddie would be their rhythm section main hold down the groove guy.
He would use Three and four note voicings or as few notes as possible - a thin - diaphanous transparent sound but that was loud enough to be heard.
Put your heart, mind, and soul into even your smallest acts. This is the secret of success.
