I postponed going on T for a long time because I was worried about my singing voice, even though I had so much voice dysphoria (like, I knew in my mind I was at least a decently good singer and was confident in my performances, but if someone tried to play a recording of me I’d have rather peeled off my skin than be in the room) and I’m telling you ITS WORTH IT ITS SO SO WORTH IT I LOVE MY VOICE SO MUCH NOW
If you can, talk to some singers who went through male puberty that you know, because if they were singing before and during, they’ll know exactly what you’re going through. I found a lot of support after I joined my area’s Men’s Chorus. You’ll have a few months to a year of embarrassing voice cracks and you’ll find notes you used to be able to sing easily just won’t come out, and it’ll make you really nervous that you’ll never get your high range back. (especially if you’ve been singing in your chest voice all the time cus dysphoria, which I found out the hard way fucked w my muscle memory for using my head voice, oops) but if you practice with a high song that you already have muscle memory for, something like an old audition song you’ve sung a million times, it’ll get much easier. (I used to audition with Show Off from the drowsy chaperone, stuff like Popular and other character voice songs can help you put the sound in the mask of your face when it’s hard to do on purpose)
Also try practicing songs by men who flip registers up and down a lot (ajr, maroon 5, etc)
My favorite thing about being on T (besides the fact that generally I no longer hate the way I sound) is that every so often I’ll be casually singing along to a song I haven’t tried singing in a long while, then go ‘woah, wait a minute, I couldn’t hit that note before!’ and it’s extremely exciting every time. Just the other day I found out that after a little over a year on T I can hit all the notes in Empty Chairs at Empty Tables!!! ^-^
I’ve always loved to sing, but now after all these years I finally love the way I sound. Don’t be scared, and don’t listen to fearmongering TERFs telling you your voice will be ruined. There’s a beautiful, rich, and vibrant tenor or baritone sound in you, waiting to come out.
