Music to hear, why hear’st thou music sadly?

Music to hear, why hear'st thou music sadly?
Sweets with sweets war not, joy delights in joy
Why lovest thou that which thou receivest not gladly
Or else receivest with pleasure thine annoy?
If the true concord of well-tunèd 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
Whosе speechless song, being many, seeming one
Sings this to thee: "Thou singlе wilt prove none."
