What does 'con fuoco' indicate in a musical piece?

The term 'con fuoco' translates from Italian to "with fire." This dynamic marking is used to indicate that the music should be performed with intensity, passion, and a sense of urgency. It generally implies a vigorous and fiery approach to the performance, evoking strong emotions and a lively character. This contrasts with other terms that may describe different expressive qualities.

While 'with vigor or spirit' might seem related, it doesn't capture the specific intensity and fervor that 'con fuoco' conveys. Similarly, 'with motion' and 'in a singing manner' define different performance characteristics. Therefore, 'with fire or fury' is the most accurate representation of how the music should be interpreted when this term is indicated.
