Sorry if this question has been asked before. I'm in my 50's and just started playing and after years of wanting I recently decided to give it ago. My hands aren't over small but I'm struggling to achieve one finger per fret. The problem is my 3rd and little finger don't want to work independently of each other and the span between the 4 frets is quite hard to reach, specially the top two strings. I can just about reach on the bottom to strings after hours of trying but it's not pretty and have to really concentrate to do it. My 3rd finger works fine if I eliminate my little finger. I've have no intentions of playing in a band and just want to play reasonably well in my living room or play along to my favourite records so the question is, is it possible to play reasonably well using just the 3 fingers, and/or will using the 4 creep up on me with hours of playing and enjoyment? Thanks.
