I've never considered myself as a musician in the proper sense due to both knowledge and skill. Just because I can play some bass and very little guitar (and have plenty opinions about music), doesn't make me a musician any more than having some practical knowledge of medicine due to personal involvement makes me a pharmacist or doctor. I know some things they do, but lack so much more. I'm fine with that. But I understand that there are degrees of musicianship involved, so in that case I'm barely a musician. But I will admit to making some better sounding music than a good number of
real musicians.
