When you play a melody in sheet music are supposed to the notes or chords?

When playing a melody in sheet music, you are supposed to play the notes indicated on the staff. The notes are represented by oval-shaped symbols with stems and flags, and they indicate the pitch and duration of each sound. The chords are notated above the staff, using a combination of letters, numbers, and symbols to indicate the specific notes that should be played together to form the chord. So, you should play the notes on the staff and use the chords as a guide to help you understand the harmonic structure of the piece and to create a richer, fuller sound.
