Some communities (New Order, Beachy) have singing schools — evening classes where youth learn to sing. Senior Vorsinger leads: learn new melodies, review old ones.
Debate
Old Order disapproves. Formal teaching = system = worldly. Singing should be passed naturally — generation to generation, without school.
Compromise
Some Old Order communities allow informal singing school — no schedule, no teacher, just 'elders sing, youth listen and join in.' The line is thin.
