I can strum guitar strings and own a guitar but am not a master of that instrument and wouldn't consider myself a guitarist.
I can hold down a beat but to use the sticks and steady on it, I can't do because I'm not a drummer.
Today I was asked am I musician. I thought about it and realized, the vocal cords are an instrument; the only instrument hand-made by God.
Yes, I am a musician. I'm a singer!!!
