Different styles

Can the note head, stem, and tail be assigned different fonts and combined in different styles?

Stems are not drawn using font characters, but you can adjust their thickness in Engraving Options.

Noteheads can be edited via Library > Notehead Sets.

Flags can be edited via Library > Music Symbols.

And, once you’ve set all these parameters, you can save it all in a personal template (I think that’s what you mean by “style”?).

Thank you.
