You may want to consider a program like OCU where you can double major in VP and MT. VPs can and do succeed in MT post grad. One recent example is Eryn LeCroy '14, who was cast as Emma Carew in the national tour of Jekyll and Hyde just weeks after she graduated. NYU Steinhardt is another great suggestion. But look at the curriculum and make sure you are taking the classes you want. VPS will take a more intensive load of music classes.
