Like for an example : Cancer in Mars means that they can sing well and play instrumetns. Something like that?
Well, it is a belief of mine that musical ability isn’t an inherent quality…so everyone is more than capable of excelling at an instrument or singing given opportunity and encouragement, etc…
I think a person’s chart moreso influences the way they approach playing music or singing.
I have mars and venus in Pisces and in musical situations find that I am almost always consenting and willing to try someone else’s idea, and can easily adapt to someone’s ideas without much struggle.
But I also have an Aquarius sun and that shows up too, because although I am willing to adjust to whatever a particular song or situation requires, I have a pretty firm notion in my head of how it will work best, and can definitely get stuck on certain things.
A guitarist I know is a Virgo sun and he has a very meticulous approach to playing and it’s good for my Pisces aspects because they like to just float around and meander when left alone, so the Virgo attention to detail helps keep my fishes on track!
