In California (during my "formative years") the Schools were well funded in the arts, and generally all round. High Schools had very good music programs and staff, but a bit difficult to get involved with unless you had come up through the school system or had developed skills through private lessons earlier..... at least in the instrumental area. Choral groups were popular and only required that you have the ability to carry a tune and take direction to participate. Concerts and productions were regular and well done.
Then we moved North into the "edge of civilization", where intramural Sports were funded, and Music not so much. There is still massive gaps in the arts due to lack of staff and funding, but the High Schools do have their Bands, and choral groups. These days supported by tuition rather than District Funding. There are 2 High Schools, 4 Middle Schools and 8 Elementary schools in town. All supported by as little as 5 Music "Teachers", with one "Band Director" bouncing between the two High Schools, and running the Music department for all of the others. They do log some miles commuting between schools !!
The Community however, has a good "base" of musically inclined folks,and between them and the Churches, most kids can have access to lessons and encouragement..... it's just not "spoon-fed" like it would be inside the School System. There are free lessons, clinics, concerts in-the-park, buskers on the waterfront, garage bands, street dances, and a few of us old hippies jammin' at the coffee houses and Pubs on any given day when the weather is not too rainy.
