I am a professionally registered mechanical engineer (received my Bachelors in ME in 1974) who was "expected" to major in music. In my case, I chose to make music my lifelong hobby, not my vocation. I have a good friend who started his college experience as an engineering major, then switched to business. Immediately after graduation, he switched schools and completed a Masters in Music (History, I think). He's been a high school band director ever since--actually, at his old high school--but has performed constantly over the past 25-30 years. Today, he has his PhD and continues to teach. He's never used his business degree. The best advice I was ever given was to do the things that bring me joy. It took me a while to think through that--exactly, what is joy? As an engineer, I've had many rewarding--and some not so rewarding--experiences. As a trumpet player, I can say the same. However, on average, my professional pursuits have brought me "joy." In the end, we all have to decide for ourselves whatever it is that brings us the most joy. The decision is not always easy. One of the saddest things I ever heard was from a local college music professor who told me he never listened to music at home. Music was his job and the last thing he wanted to do at home was work at his job. So, he golfed. However, just imagine how sad that sounds--a musician who doesn't listen to music at home! Depending upon how much time you've already invested in your engineering education, you just might want to consider finishing that program, then pursuing a second degree in music, either at A&M or elsewhere. Who knows, you just might end up designing and building trumpets for a living!
