Well, I mean, duh! Singing! But, like, does it help people with their pitch, or like range, or like the sound of their voice? Cuz I already know all the musical technical stuff, since I've played the piano and clarinet for a while. I've considered taking voice lessons, but don't want to wast my time and money if I'll just be relearning how to read sheet music . . . So, anybody know?
no, most singing singing teachers concentrate on the actual mechanism rather than music theory.
We help you learn to play that most elusive instrument, the voice. Since you can't take it out of its case, or polish it, or even see it without the help of highly technical and expensive equipment, the teaching of voice is still very imprecise in its methodology. No two teachers ( unless they trained together) will use the same set of vocabulary with just the same meaning, so a lot of semantics is involved as well.
Since most of the major musculature of the voice is involuntary, you will have to learn by "feeling" your voice, rather than listening to it. ( if you've ever recorded yourself, you know that the sound "in" your head is not the sound the rest of the world hears.)
It is painstaking, simply because there are so very few visual references to go by.
Your previous musical training ( especially breathing from clarinet) will stand you in good stead, but be prepared for something completely different as far as the teaching goes.
Best wishes and keep on singing
