This is so subjective, has so many variables, that we all have our own individual ideas of what is ‘good’, what constitutes a ‘10’ on our own individual scale. There is no yardstick outside of of our likes and dislikes that has an inherent objective scale from ‘bad’ to ‘good’. Take Jah Wobble for instance, he is one of my favourite bass players. If I had to to explain why I would have to link it back to one album, Metal Box, then to refine my explanation in order to define what it is about his bass lines on that album I realise that almost every single definition I come up with is connected with a host of feelings, subjective notions, memories and just a huge stack of junk. I can describe some of his bass lines as ‘sublime’ in my opinion but I do not attempt to emulate the myriad qualities within those basslines in order to become a ‘better’ bass player because I realise that those basslines are a subjective meeting midway between me as the listener, hearing the line with all my likes, dislikes, peccadilloes and the line he is producing, with all his likes, dislikes and peccadilloes. My idea of a ‘good’ bass player can only ever be a Venn crossover between my subjective junk yard and Jah Wobble’s. Music is art, art is subjective. If music moves me emotionally then I consider it good, not good generally but good in my mind to me and that sense of good is impossible to define.
