<p>When you say a minor in music, do you mean in instrumental studies, or do you mean taking classes like music theory and such as you would in a BA program? Music minor can mean different things…which raises the question, why get a minor in music? It sounds like you are thinking of it as a possible alternative path into going into music, and quite honestly, I am not sure a minor in music would do much there (other then taking some courses in music, not a bad thing). </p>
<p>You could learn those instruments on your own or have private teachers, through tehe school or not, and accomplish the same goals, and even assuming you could do that as a minor, not sure what value that would have either towards going into music or physics. If your idea might be someday to join or form a band, or be some sort of singer/songwriter, having a music minor probably wouldn’t do all that much towards that goal IMO.</p>
