The part-symbol element indicates how a symbol for a multi-staff part is indicated in the score. Values include none, brace, line, and bracket; brace is the default. The top-staff and bottom-staff elements are used when the brace does not extend across the entire part. For example, in a 3-staff organ part, the top-staff will typically be 1 for the right hand, while the bottom-staff will typically be 2 for the left hand. Staff 3 for the pedals is usually outside the brace. |
