How would someone with a terrible singing voice go about learning to sing?
And is it even possible to develop an appreciable singing voice?
Edit:
I already play guitar, bass, and drums. I just want to learn to sing so I can write and perform my own songs. I have a lot to get out of my system ๐
As the spouse of a singing teacher... Take lessons from a trained professional (someone that has a degree in vocal pedagogy and / or vocal performance) and practice regularly. Don't expect to be amazing overnight. It may take years of lessons and daily practicing to just get to a level where people don't cringe when you try to sing something.
