Re: Difficulties using a piano-template

[Mats Bengtsson]

The problem is that the commands \clef and \key are only recognized
correctly if you are in \notes{...} input mode. So, either move your
settings of \clef and \key into your definitions of upper and lower
or add a \notes when you declare your Staff contexts:
\context Staff = upper \notes{
    \clef violin \key f \major \time 2/4 \upper }
\context Staff = lower {\clef bass  \key f \major \lower }

I find your use of << and >> quite confusing. First of all, you could
just as well use {...} as long as you don't have several simultaneous
voices in the stave. Also, you have declared the Staff "lower" as a
part of the Staff "upper", since the >> that matches
 \context Staff = upper <<
is inserted below your declaration of the lower stave. My example above
should solve also these problems.

Finally, many people use an extra variable for common declarations that
should be included in several staves. For example, you could do:
global = \notes{\key f \major \time 2/4 }
and use it with
\context Staff = lower \notes{\clef bass \global \lower }
