OCU has a great music education program as well as terrific instrumental music training. Like Otterbein, student orchestras routinely provide music for shows. There are opportunities to be in all sorts of ensembles. They also have a strong composition program if he is interested in writing music. OCU also has a Theatre for Youth program he may find of interest. Oklahoma Children’s Theatre resides on the OCU campus. I believe you must audition for instrumental music. Not sure the requirements for music education. Might be worth a look!
