Which term indicates a stressed or marked note in music?

The term that indicates a stressed or marked note in music is "marcato." This term instructs performers to play a note with emphasis, often making it stand out from the surrounding notes. Marcato is represented by a specific symbol, typically an inverted V or wedge above or below the note head. This indication is crucial in conveying the intended character and emotion of a piece, as it guides the musician in interpreting how certain notes or passages should be highlighted, creating a more dynamic and expressive performance.

In contrast, "legato" refers to a smooth and connected manner of playing where notes are performed in a flowing style without perceptible breaks. "Largo" denotes a slow tempo, suggesting that the music should be played at a leisurely pace. "Hemiola" describes a rhythmic pattern where two groups of three beats are juxtaposed with three groups of two beats, creating a feeling of shifting accents but does not specifically indicate stress on a particular note. Each of these terms serves different functions in musical expression, but when it comes to marking or stressing a note, marcato is the appropriate choice.
