[linux-audio-user] Magnifying LilyPond output by using landscape mode?

[Mario Lang]

Hi Janina.

No, that doesnt help :-).  Since I am not trying to actually read the result,
I just want one tactile example for getting a feel about how
visual music works.  Again, I am not trying to read this with my eyes,
just trying to get a representation I can touch.  It sounds strange maybe,
but experience taught me that it is very useful to have a grip on how
the sighted world actually works with things.
