I found something interesting from this PDF (
http://www.unicode.org/charts/PDF/U1D100.pdf):1D173 MUSICAL SYMBOL BEGIN BEAM
1D174 MUSICAL SYMBOL END BEAM
1D175 MUSICAL SYMBOL BEGIN TIE
1D176 MUSICAL SYMBOL END TIE
1D177 MUSICAL SYMBOL BEGIN SLUR
1D178 MUSICAL SYMBOL END SLUR
1D179 MUSICAL SYMBOL BEGIN PHRASE
1D17A MUSICAL SYMBOL END PHRASE
how does Bravura able to connect notes with beams regardless of how width the gap between each others?
