#### 3.14.1 Multiple staff contexts

Polyphonic scores consist of many staves. These staves can be constructed in three different ways

- The group is started with a brace at the left, and bar lines are connected. This is done with the GrandStaff context.
- The group is started with a bracket, and bar lines are connected. This is done with the StaffGroup context
- The group is started with a vertical line. Bar lines are not connected. This is the default for the score.
