This is called the Grand Staff. It is commonly used for instruments with large ranges such as the piano and the organ. On the piano, the right hand usually plays the notes written in treble clef, and the left hand plays the bass clef notes.
The grand staff consists of a treble stave and a bass stave. They are connected by a vertical line creating a "system". The presence of this vertical line signifies that the two staves (treble and bass) are to be played at the same time.
The grand staff in music is a combination of the treble staff and bass staff, connected by a brace and a line. The treble staff is used for higher-pitched notes, while the bass staff is used for lower-pitched notes. The grand staff is commonly used in piano music to notate both hands' parts simultaneously.
