Sheet music is a written record for performance that notates pitch, duration, dynamics, and more. A score refers to sheet music where several parts are stacked vertically so that you can see the whole piece.
How to use it
You read the melody, rhythm, chords, and performance markings from it so that every part shares the same structure.
How it differs from related terms
Sheet music is the broad term, and a score is the format for checking a whole ensemble.
Even in music production, being conscious of the relationship between bars, beats, and parts makes the thinking behind notation useful.
