@Jenetrix I'm not an enby (as far as I can tell) but that's also a goal for me. If I ever find the executive functioning to actually do voice training.
Not quite on that note ... I always had a hard time singing when I was younger. It turned out I thought I had a fem vocal range, but actually it's between baritone and bass.
Taking a sight singing class as an elective in college cured me of that: and I surprised the instructor when I chose to sing the duet for the final as the baritone it was written for (I was very fortunate that class was graded on improvement!)
I still think of myself as about 10% shorter than I really am.
