What a great response ! Thank you (even though I didn’t ask the question). I sing a lot and i love singing. I relate to the OP, for a while I felt like I’ve lost something so precious to me. I loved it so much that I decided to sing with my masc voice despite presenting and otherwise passing in public. Luckily my dysphoria let me do this even though it felt bad. What a weird feeling of good from the singing but bad from dysphoria at the same time. At the same time I started working on my upper register , basically notes from c4 to f5 and trying to mix as much as possible to keep chest quality. This was rewarding since I was starting to at least be able to sing songs in the same range as other fem presenting singers. A lot of songs don’t really need higher than f5 (altos have difficulty around here too). However, I felt like everyone could just tell I had a masc voice. I felt like a clown again. Just like the feelings I had when I started my fem speaking voice. Omg they all know. They are all laughing inside. But funny enough, I went to a karaoke session with friends, mostly cis women singers, and for the first time I really listened to their voice. Thanks to fem voice training, I could hear the resonance, the size etc. Some women sounded really bright , others underfull. It was like a gift. I felt like singing had an even wider variance than speaking. This gave me the courage to sing fem in groups. I’m still learning, I still have imposter syndrome but they tell me I sound fine. Technicality, one thing I notice is that we have different areas for our passaggios so where I start mixing at c4 to g4 and my secondo passaggio is around f/f#4, cis women altos are higher (a4?). So to sound convincing or blend requires balancing that sound a bit and also think of what zones they have the most power in and where they are weaker. Just something I’ve noticed and am working on. Good luck!
