What defines the Grand staff?

The Grand staff is defined as a pair of five-line staffs that are connected by a brace. This music notation system is primarily used for piano music and allows the representation of both treble and bass clefs, which correspond to different ranges of pitches. The treble clef is typically assigned to the upper staff, while the bass clef is used on the lower staff. This structure enables musicians to read and play music that encompasses a wide range of notes, as it combines both higher and lower pitches effectively.

Using a Grand staff facilitates complex compositions by clearly indicating the relationships between different notes and harmonies. It is a foundational element in learning to read music for instruments that require coordination between both hands, as is common in piano playing.
