I have a tenor voice with the range and everything, I can easily acces my head voice without tension a and some days my whistle register, but for some reason my voice sounds awful , my tone in particular, in my head voice although easy, lacks vibrato and melody ...I sound nasal in all my registers , regardless of the effort I put in to breath support, my voice in general sounds ear grating and lacks genuine and unique melody...it's awful and I hate it. what do u do to improve my tone. And also my falsetto is just heartbreaking...I'm just tired.

Hi, Joshua! I recommend watching the following lessons on tone and vowels. You can drastically change (and improve) your tone when you understand your resonators and vowels!
