A collection of lines on a music sheet is composed of a series of five lines and four spaces that are used to represent pitches and notes in musical notation. These lines and spaces are called a staff (or stave), and they’re used to keep the music organized and to make it easier to read. The lines and spaces are numbered from bottom to top, starting with the bottom line as line 1 and the top line as line 5. The notes are placed on these lines and spaces, usually with a clef symbol at the beginning to indicate which notes correspond to which lines and spaces. There are various clef symbols, but the most universally recognized is the treble clef. This clef symbol tells the musician that line 1 is a G, line 2 is a B, line 3 is a D, line 4 is an F, and line 5 is an A. Notes written above or below the staff are indicated by ledger lines. Notes placed on the lines and spaces will correlate to a particular pitch, so the music notation creates a complete picture of the composition.
