I play the guitar and play a lot of jazz where singing isn't required. However, sometimes I play folk songs or even a jazz standard, and I want to just be able to sing the lyrics. I'm not trying to be an incredible singer. I am really looking just to be able to sing and not have it ruin the song.
Sometimes I feel like I'm trying to sing and I can no longer speak. Like, notes that are well into my vocal range just sound like absolute shit.
I have been taking guitar more seriously and realize the level of work it takes to actually get good at guitar. I realize singing is more or less just like any other instrument. So it doesn't surprise me when most of the resources I find for learning to sing are a pretty thorough collection of exercises, techniques, warmups, etc.
I would be interested in that, but I'm also just trying to find a quick jump start. Like the guitar equivalent of learning open chords where you don't sound like a virtuoso, but if you learn four chords, you can pretty much simply play the chords to a lot of songs. It's elementary, but it's somewhat passable. Is there any procedure like this for learning to sing?
