G, C, D and the occasional Em can last a life time – particularly with a capo. But for others weird inversions and alternative tunings are their stock and trade.
I’ve worked with limited musicians who make amazing music and outstanding musician who can’t get past theory to an original thought!
There is predominance in our culture towards ‘immediate perfection’ and that there is some sort of pre-ordained right way – I think Plato started it all with ‘looking out of a cave into the twilight or something like that’.
Do what gets the job done, when you know what the job is you are doing.
I believe in evolution – adapt or die – if 4 chords can last a whole career then why change there is nothing to get annoyed about; there is a beautiful efficiency (Crocs are the 4 chord rock stars of evolution) – if the day comes that a 5th chord is needed and the artist cannot play it the I guess they wither and die or they get a session muso?
I agree; don’t over think it. The more you get bound up in judgements about process or other people’s practice the more crippled you will become. Look at everyone, steal everything and keep what works for you – you are only doing what happy and successful artists have done for millennia
