So, of course being me, I took it upon myself to look up youtube videos and read forum posts on how to reach a feminine voice. But what did I do? I got overzealous and cocky, and practiced too much too quickly at too high of a tone. I have strained my vocal cords I believe. They are very tense and sore, with a bit of a dryness. My voice seems pretty much fine... it's not hoarse or anything like that. It IS tired though, and it's not as readily useable as it should be. There is also a bit of pain in my upper chest.
Does anybody have some advice on how to perhaps relax my vocal cords, or at least prevent permanent damage whilst they heal themselves?
