i started playing clarinet for pay at the age of 10 (1962) in a school based 'orchestra'. we played mainly parades, outdoor events, summers only. got paid $5 each for a few hours of 'work'. did that thru 8th grade.
then didnt play for $ again til '73 and '74 when i took up 'lectric bass and joined a band in tokyo, japan whilst in the service. played a few gigs there, mostly on u.s. bases and a few small japanese night clubs. we got anywhere from $100 to $200 per gig,
split 4 ways.
out of the service 7-'74 and on to reno, nv. joined a bunch of bands, one at a time, mostly garage bands. nv is a union state. the major clubs and casino showrooms are (were in the '70s-dont know about now) union only. we played a bunch of small bars and nightclubs for not much $, maybe $200 max for 5 of us

.
moved back to vermont, new hampshire in '81, joined a few rock and country bands. plenty of work around here in the '80s; $200 to $500/gig.
the county gigs sucked cuz you had to get your own lodging. most of the rock gigs were thru an agency, paid much better than the country gigs and you got a house or apt to stay in. sometimes meals to

it's definitely a bit(h trying to make money as a performer. the vast majority of the time i had to have a day job to support my music habit. by '85 i didnt have to work a day job for about 1 1/2 years but was on the road constantly (regionally-new england=boston to montreal), no home life, too much alcohol, etc.
i 'retired' in '91 and i dont miss it at all. which makes me feel guilty. a little.
all thru my performing 'career' (late '70s and '80s) i ran a 4 track recording service, mostly remote, made a few buck from that, made a few 45 records too. they sounded good on local jukeboxes.
too bad we didnt sell millions of 'em.
