Education in music is most sovereign because more than anything else rhythm and harmony find their way to the innermost soul and take strongest hold upon it

Above all they must maintain the educational system unchanged; for on education everything else depends, and it is an illusion to imagine that mere legislation without it can effect anything of consequence.
