<p>You won’t have to pay more TUITION per say because you’re set at 18 units a semester. You might have to pay more money because a double major MIGHT require staying on an extra semester or taking summer classes. Pretty much all the arts-based schools have class fees, usually to cover the cost of student’s using the school’s equipment (in this case, instruments.)</p>
<p>You’ll have to see the course plan for each program to see if you can graduate in 4 years. My BFA program had something like 136 units (?) and I had to take two semesters of summer classes to graduate on time with a minor.</p>
<p>I know performance majors have a LOT of required units and take a lot of time; I don’t think something so intense like business and a performance double major would be the best idea. A minor should suffice if you don’t want to become a professional touring pianist.</p>
<p>You posted this in another thread – do you mean PRIVATE piano teacher (like for kids who want in home lessons?) A minor for that should be fine if you are good enough. Anything else (college, high school, elementary) at an actual SCHOOL would require a DM in music education, a MAT or an education credential. Some private piano schools also like to see teachers with more practical experience (in orchestras, tours, etc) and don’t care so much about degrees.</p>
