You should stay where you are, retake the class, improve your GPA, and then try again. It’s not the GPA that’s the problem. It’s the failing grade followed by an immediate attempt to transfer. That’s not going to look good on your application, whereas showing that you can try again and succeed will look better. As for taking classes that don’t move you forward on your career path, keep in mind that the first thing you need to do is complete your education path. Since you aren’t attempting to graduate from your current university, you are free to fill up your remaining credit hours with any classes you want (plus the class that you are going to retake). Maybe you could take a music class. But even if you can’t, music programs still have distribution requirements. Temple, for example, requires music students to complete the university’s General Education curriculum. So take classes that will make it easier to focus on music and music education after you transfer. One last thing: music education is a fairly demanding major, and very few music schools accept students who do not have significant prior experience with music. So before you plan your life around this major, you should contact some people at Boyer College (Temple’s music school) and make sure you have the background they are looking for. You probably won’t be able to speak directly to a professor right away, so start with the main office and see who they direct you to for more information.
