Sonnet 8

Music to hear, why hear'st thou music sadly?
Sweets with sweets war not, joy delights in joy:
Why lov'st thou that which thou receiv'st not gladly,
Or else receiv'st with pleasure thine annoy?
If the true concord of well-tuned sounds,
By unions married, do offend thine ear,
They do but sweetly chide thee, who confounds
In singleness the parts that thou shouldst bear.
Mark how one string, sweet husband to another,
Strikes each in each by mutual ordering;
Resembling sire and child and happy mother,
Who, all in one, one pleasing note do sing:
Whose speechless song being many, seeming one,
Sings this to thee: 'Thou single wilt prove none.'

The sonnet describes ones self interest in music and life. I think it has to do with someone being upset. If you hear such joyful music why are you still upset? You act as if you are annoyed by the music and your ears are so offended. Each string resembles the beauty of family yet being single proves nothing which this person will wind up because they are obviously so cold
