What does 'con forza' direct a musician to do?

The term 'con forza' is an Italian musical directive that translates to 'with force' or 'with strength.' Therefore, when a musician sees this instruction, it signifies that they should play the music assertively and with a strong emphasis, enhancing the dynamic intensity of the performance. This directive could be applied to various sections of a piece to create emphasis or drama, encouraging a vigorous execution of the notes.

The other options suggest varying interpretations, such as playing comfortably, with movement, or with grief, but none encapsulate the essence of 'con forza' as effectively as 'play with force.' In this context, it is essential to understand how musical terms shape a performance's character and how they guide interpretations beyond just the notes on the page.
