What type of articulation tells the musician to play a note with heavy emphasis?

The type of articulation that instructs a musician to play a note with heavy emphasis is called "accent." In musical notation, an accent mark is placed above or below the note, indicating that it should be played louder or with more force than the surrounding notes. This emphasis can add expressiveness and dynamics to the music, helping to shape the phrasing and emotional character of a piece. There are different types of accents, including the "sforzando" (sfz), which calls for a strong, sudden emphasis on a note. Understanding the use of accents is essential for musicians to convey the intended mood and dynamic range in their performance.
