Building a Musical Staff
The staff is a set of five horizontal lines containing notes and musical symbols. When notes are found off the staff, they are placed on ledger lines.
Measures
A measure is a section of the staff that comes between two bar lines (or barlines). Each measure satisfies the time signature; music written in 4/4 time will have four beats per measure.
Double Bar Lines
A double bar line is used to separate different sections of a song. It marks the transition into a different time signature, key signature, or overall style.
- When a double bar line is in bold, it marks the end of the song or movement.
Note: The plural of staff is staves.
