Yes, she is.
And I've seen statues of her with some kind of stringed instrument...maybe a lyre. I don't think she ever played any instrument but she is the patron saint of art and music.
The town I grew up in is Kearny, NJ. It was named after it’s most famous local son, Union General Phil Kearny. I don’t know if you ever watched “The Sopranos’’. I never watched more then a few minutes of a couple of episodes. It was filmed in Kearny. In a number of the scenes where ‘’the gang’’ is hanging out at their club that’s filmed on the main street, Kearny Ave. Right up the block in many scenes is a church. That’s St. Cecilia’s Church. That’s the church my parents were married in.
