Hi M.. My husband is a professional musician, and we both majored in music performance in college. Please, if your son wants to play violin or cello, let him. There are a few things to consider here. The first I know is a little far-fetched. Should your son somehow ever want to pursue music as a profession, there are so many more jobs for string players in the world! This is because in any given orchestra, you can have 50+ violins and 20+ cellos compared to about four of every wind or brass instrument. The second thing to consider is difficulty. Generally speaking, string instruments are easier to pick up. Why do you thing there are so many guitar players! String players have a very clear advantage to wind and brass players. They can visually and audibly tune their instruments, whereas winds and brass have to rely much more on their ears. For example, if a string player plays an A and it's out of tune, they can look at their hand while they move it to the proper position to get it into tune. A trumpet player pushes down a key and if it's not in tune, they have to fix it without seeing what they're doing, usually by adjusting the embouchure. I understand your thinking that winds and brass have more opportunity, but when you consider things like the Wichita Symphony Youth Orchestras (whose youngest orchestra, the chamber players, is composed entirely of strings), I think you'll discover that there are plenty of opportunities for string players. And if you're that concerned about it, maybe you should suggest the upright bass to your son. That way, he could play in orchestras and jazz bands! And one comment about marching bands--if your son goes to a school that requires marching if you're in the band program, there's a good chance that marching band will not be fun. Marching band sometimes is really hardcore, and over the years, we've found that it does more to mess up ones face (you have to play really loud because you're outside) and limit ones musicality than anything else. My husband, who teaches privately, has limitless stories about players coming to him in the fall during marching band season with embouchure problems. Usually all of the juniors and seniors hate marching band. Just one more thing. If you can afford it, might I suggest getting your son started with a private teacher? It will do so much for his development, you won't believe it. And just so you know, my husband and I are both brass players. We've both said that when our kids are at the age to play an instrument, we will gently suggest a string instrument, but we will allow them to pick what they want in the end.
