That did it.  Thanks, Ernest!

Jazz is an old 3rd party font that is included but no longer supported by MakeMusic. You can still use it, of course but if there are any issues, consider switching to Broadway or Broadway Copyist as MM will never update Jazz. Per the User Manual:

The Jazz font was the premiere handwritten music font prior to Finale 2010 and includes handwritten text, percussion, and chord symbol fonts as well.

 

There is an SMuFL version in 27 but still…

Hi Mike.  Thanks.  I found the FinaleJazz notation.  It's pretty good--not as good as the original Jazz, but pretty good. It's annoying that Finale doesn't automatically switch the text to Finale Jazz text when you choose FinaleJazz notation.  I set up a template for my horn section charts using the FinaleJazz notation, but I had to manually change the title, subtitle, etc to Finale Jazz text for each field.   It looks like some of the expressions (articulations and dynamic markings, for example), automatically appear in Jazz text, but other expressions (rehearsal letters, tempo markings, etc.) still appear in the default font.  I'll have to keep playing with it to figure it out.
