I love a Capella singing, but my voice is not up to it for most songs. My brothers and I have done some quartet singing without instruments, but I'll leave the solo singing to someone else.

Something I heard someone say the other day bothered me a bit. They said that So-and-so would be worth going to see even if they didn`t make any music.
I asked if he meant if they just told jokes or stories.
He said he meant if they just sang unaccompanied.
Singing unaccompanied can be making music as much or more than playing an instrument.
