The man that hath no music in himself
Nor is not mov'd with concord of sweet sounds,
Is fit for treasons, stratagems and spoils;
The motions of his spirits are dull as night,
And his affections dark as Erebus:
Let no such man be trusted.
Merchant of Venice, Act V.
By the way, Ralph Vaughan Williams has used that Shakespearean quotation as text for his Serenade to Music. It's a lovely choral piece with a fascinating story attached to it. I should write a page about it some time.

From being a composer of rag-time, Scott Joplin began to interest himself in music for the stage. First it was dance music. Gradually it developed and culminated in a work he called Treemonisha -- a strange mixture of rag-time and grand opera. It was misunderstood and rejected; those who appreciated rag-time couldn't understand it, and those who loved opera simply didn't want to know about something written by a Negro.
The rest of the story is one of rejection and a gradual decline of health -- the result of syphilis. Fortunately for posterity, Scott Joplin published Treemonisha at his own expense. It was never performed in his life time. A run through of the score at an audition intended to attract backers was the closest he got to hearing his work.
