Hi Stefano,
if you write
{ \clef F <<
as in your file eetest-not-working.ly you have this in your Staff
context: \clef F and then afterwards two voices at the same time.
More explicitly, your code is interpreted as somthing like:
\new Staff {
\new Voice { \clef F
<<
\new Voice ...
\new Voice ...
>>
}
}
The \clef F can not be without bottom context so a Voice context is
created automatically. This is your voice A but it does not contain notes.
Your explicit voices are probably named B and C (I have not checked) so
you can address them via B and C.
Or you can put the clef inside the first explicit voice which is then A
again.
HTH,
Joram
