Good evening, this is from a student concert at the Megaron Concert Hall in Athens with my conservatory, after about one year of studying music (with no prior background). I sang yesterday "Hör ich das Liedchen klingen" - even though I don't speak German, I did my best &. I'm still exploring my technique and I notice I tend to create tension in my tongue and larynx, and that my mouth opening can be a bit restricted at times, especially in more demanding passages. Id really appreciate any tips or exercises that could help me find more freedom. Thank you
