Hello! I love classical singing music, and listen often. I only sing in the shower and when I listen to music, but now I want to take lessons. But first I will read about it, and watch Youtube videos. recorded voice range: Lowest note F, and highest c2 (tenor high c). But my personal best is Eb and d2 sometimes. Which is my vocal fach? My tessitura`? Thanks for helping!
