|A Music Staff is a set of lines and spaces. The music staff was inspired by the frets on a guitar. At first notes were written only in the spaces.|
|Both lines and spaces have been used for the last millenium. Though three- and four-line staves were common at one time, today we use a five-lined staff. Each line and space represents successive letter-names. What those letters are depends on the placement of the clef.|
| When notes go off the staff there are three options.|
1. Extend the current staff with LEDGER LINES .
|2. Change the clef.|
|3. Us "8va" to shift the octave as indicated at right. |
8va means an octave higher and 8ve, or 8vb, an octave lower. Sometimes 8va is used for an octave lower. The bracket shows the direction.
