As someone who has a master's in music, I can honestly say that I have learned more about singing and vocal production from Sweet Adelines International.
I don't know why, but I knew since elementary school that I was going into music; before I even studied an instrument. Then my father surprised me on day; he bought me a piano.I took piano lessons at age thirteen, and have probably the only parents that would beg me to stop practicing. I was a piano performance major for two years in college, but in my sophomore year, when seniors were starting to student teach, I realized that teaching is something I would love to do. I switched my major to music education, and I have never regretted it. I love to teach music.
So with that in mind, I want to encourage you to learn to read music. It's no great mystery. You will also be able to read key signatures, and when your director says, blow the pipe, you will have already written down all the keys of every song on your own!
It's not a necessary ability, but why not? If you love singing, then you can pick out your own part on a keyboard at home. You can help in section rehearsals. You can help someone else who needs to fix some wrong notes. The pluses far outweigh the negatives.
So think about the possibilities open to you when you open another door to music; you won't regret it!
