Pardon the thread creep, but I think there is too much reliance on internet and the like these days, where self styled experts show you where to put your fingers, rather than you having to work out for yourself where the notes are on the fretboard and what note combinations are needed to form particular chords. My favourite cringe was a YouTube video where the ‘expert’ confessed to not knowing the note of the open botttom string, but constantly referred to it as ‘this fat string here’. Whether such people should be allowed to teach others is a matter for another thread no doubt, but there is a lot to be said for the approach of classical musicians. Having mastered the basics on your chosen instrument, then take time out to learn another instrument(properly that is, not in a guitar like chord style), then return to your first instrument, which you should find much easier to play and navigate. Previous’ generations of course learnt their way around the fretboard, how to play scales, etc, before learning about chords and harmonic progressions, now we teach all that in reverse, so it’s no wonder we reach plateaux. Plenty to argue with there, I’m sure.....
