[CM] first steps --- just testing

[Bill Schottstaedt]

> 1. How to make cross-staff groups?

groups of what?  There's an example of beaming across staves in
cmn-ex.lisp under "beaming across multiple percussion clefs".
Other things (such as slurs across staves) are handled similarly.


> 2. How to handle vertical position of lyrics?

The dy message is probably the simplest.  There's an example in cmn-ex.lisp under
"brace connecting two lines of lyrics".

Yes, or use lyrics.lisp; see also jimmy.cmn.

See "lining up notes" in cmn-ex.lisp.  This part of cmn is unnecessarily difficult.
