Well Ive actually been wanting to add lyrics and singing to my music, which is actually the biggest thing holding me back on an album, believe it or not : p But Im not really good at either singing or lyrics, haha. I usually feel goofy when I try to do it, and feel discouraged, and thats the biggest road bump I have right now. I actually have many song ideas that Im super excited about, but wont record them because Im afraid if I do Ill never work on the lyrical part. But I actually do have two that are ready to go, lyrics and singing included. Maybe Ill record them soon and post them here.
And yeah, I use my pinky alot in playing : p Alot of the chord changes you hear me play, theyre really just me holding down one chord and moving my pinky around, haha. Even just changing one note of a chord can completely change a song entirely, I love that about music.
Well, there's never any rush to showcase your vocals. Don't be hasty and post anything you'll regret right afterwards. Just practice up and watch different guides on elocution exercises and singing until you are comfortable enough with your voice. There's loads of helpful stuff on Youtube, but I'm sure you already know all this!
