I guess I'm lucky, I have an easy choice: St. Cecilia
She was the saint name I chose for my RC confirmation.
She is a pre-schism saint.
Her name is similar, phonetically, to mine.
She is, among other things, the patron saint of music/musicians (I sing, play instruments).
Her feast day is, coincidentally, on my birthday (November 22)
I can't see making another choice.
