Structure

Supported structure

This library supports the following structures.

• Repeat
• Repeat with variation
• Da Capo (D.C.)
• Dal Segno (D.S.)

Detailed structure

Region:

graph LR S(( )) --> CR[Compound Region] --> E(( )); S --> DS[Simple Region] --> E;

Compound region can contain D.S./D.C. Segno, Fine, and Coda can be used with D.S./D.C.

• Segno must be located before Fine.
• If D.S. exists, one Segno must be located.
• Segno should not be used without D.S.
• If D.S. nor D.C. exists, Fine should not be located.
• If D.S. nor D.C. exists, Coda should not be located.
• The number of Codas should be zero or two.
• If there are Codas and Fine, Codas should be before Fine.

Compound Region:

graph LR S(( )) --> R[Simple Region] --> E(( )); E --> S;

Simple Region:

graph LR S(( )) --> SR[Sequence Region] --> E(( )); S(( )) --> R[Repeat Region] --> E(( )); S(( )) --> V[Variation Region] --> E(( ));

Sequence Region:

graph LR S(( )) --> N[Bar] --> E(( )); E --> S;

Repeat Region:

graph LR RS[Repeat Start Bar] --> SE[Sequence Region] --> RE[Repeat End Bar];

Variation Region:

graph LR C[Common Region] --> V1[Variation 1] --> R2[Variation 2] -...-> Rn[Variation N];

• At least two variations shoud be located.

Common Region:

graph LR S(( )) --> SR[Sequence Region] --> E(( )); S(( )) --> R[Repeat Region] --> E(( )); E --> S;

Variation:

graph LR S(( )) --> SR[Sequence Region] --> E(( ));
