Most musicians tour? Hmm. I don't have stats, but I doubt 95%+ of musicians ever tour, or hardly ever. The vast majority of musicians I know (musician here) pay their bills, support their kids etc by regular teaching, supplemented by gigs. Virtually all gigs are very low-paying compared to a few decades ago. A bass player friend told me that in a big city music venue, in the 1980s he was making 10x what the bar staff were; now they get paid more per hour.
