A staff is made up of five horizontal lines and four spaces.
Pitches are named after the first seven letters of the
alphabet (A B C D E F G).
A clef is a musical symbol placed at the beginning of
the staff that determines the letter names of the lines
and spaces.
The two main clefs are the treble and the bass:
and bass clefs connected by a vertical line on the
left side of the staves (plural staffs).
Ledger Lines are an extension of the staff. They are additional lines both above and below which are parallel to the staff. Each ledger line contains one note.
