What is the relationship between Saint Cecilia and the music?

Pope Gregory XIII declared Saint Patron of music and musicians in 1584 to Saint Cecilia, because of the great popularity that this martyr's association with music had acquired.

There are two reasons between myths and legends that lead to the relationship of the saint with music.

Some think because it is said that when she married by her father's wish, on the day of her wedding, while the musicians played, she sang to God in her heart.

Probably also, because from a young age and according to the customs and traditions of the Roman patrician families, Cecilia had to start and play some musical instrument, such as the lyre, the zither or some type of harp used by the ladies of the Roman society.

Beyond the bond that the saint may have with music, the most important thing in her is that she died defending her Christian faith like so many martyrs.
