The term accent means that if you play a chord on the piano, like an Am, you play it quietly, softly press the keys, and suddenly, violently attack the keys by pressing them harder, making the volume louder, but that is if you have a good piano, because some cheap piano's make the same volume no matter how hard you press the keys.
The different types of accent in music include dynamic accents, agogic accents, and articulation accents. Dynamic accents are emphasized notes played louder, agogic accents are notes held longer than others, and articulation accents are notes played with a specific attack or articulation.
The accents on beats 2 and 4 in rock music are known as the "backbeat."
To accurately interpret and perform sheet music accents, pay attention to the symbols indicating accents and play those notes with more emphasis or force. This can enhance your musical expression by adding dynamics and shaping the music's phrasing. Practice playing with accents to develop a sense of musicality and bring out the intended emotions in the music.
