He dances well to whom fortune pipes.

A person can perform well when circumstances favor them. The image of dancing to fortune’s music presents success as easier when opportunity arrives at the right moment.

The proverb tempers praise for an achievement by suggesting that luck may have helped make it possible. It need not deny the person’s skill; it asks that favorable conditions receive some credit too.

Use this proverb when someone’s success has been helped by unusually favorable circumstances, especially if others are treating the result as proof of ability alone. It can also acknowledge an opportunity that made a difficult task easier.
