In sweet music is such art: killing care and grief of heart fall asleep, or hearing, die.
William ShakespeareThus play I in one person many people, And none contented: sometimes am I king; Then treasons make me wish myself a beggar, And so I am: then crushing penury Persuades me I was better when a king; Then am I king'd again: and by and by Think that I am unking'd by Bolingbroke, And straight am nothing: but whate'er I be, Nor I nor any man that but man is With nothing shall be pleased, till he be eased With being nothing.
William Shakespeare
