Hi Levi
You have taken this example from a section of the manual which has not been
updated recently, and I can see why it might be confusing - if you remove
the two statements which create the Voice contexts the example still works
perfectly in the more recent versions of the LilyPond. If you have not
already done so, please read section 3.2.1 in the 2.11 Learning Manual
called "I'm hearing Voices", but here's an explanation of this particular
piece of code.
First, all notes -must- be contained in a Voice. If a Voice is not defined
explicitly one is created behind the scenes.
To explain, first consider the example with the two lines beginning \new
DrumVoice removed.
The construction following \drummode contains two bars of music. The first
bar ( bd4 sn4 bd4 sn4) goes into a default Voice context, as one has not
been explicitly created for it. This is followed by a << ...\\ ...>>
construct for the second bar. This construct places { \repeat unfold 16
hh16 } in a Voice called "1" and { bd4 sn4 bd4 sn4 } in a Voice called "2".
If these voices have not been explicitly defined they are created "behind
the scenes" automatically with these names. The music in these two voices
is then played in parallel, both in bar 2. Two voices are required because
the rhythms are different.
Finally, in earlier versions of LilyPond, the voices "1" and "2" had to be
explicitly defined before they could be used, hence the explicit
declarations \new Voice etc in the example you quoted. The {s1*2} following
simply enters two bars of skip notes, and these are in parallel with the
rest of the music due to the << .. >> round the contents of \DrumStaff.
HTH. I'm afraid I can't help with Open Office though.

Subject: OOoLilypond instilation problems and coding help
I am running windows XP (with sp2) and open office v 2.0.2 . I followed the
instructions on using lilypad with open office. I have downloaded (and
written in) the lilypond script as well as the open office macro, i
installed the macro as said in the instructions, but when i press alt m an
error orccurs. The message is this: "BASIC syntax error. Dimension
specifications do not match." it highlights a portion of the
code:"SortStringArray(sTemplate" approximately 4/5ths the way down the page.
I cant get the macro to work, can anyone help me?
On another note, I am reading the tutorial and manuals for lilypond, but am
having trouble assimilating all the information. I have done some html and
java programing so im no stranger to computer code, but the "voices" concept
is giving me trouble. I am using this program to write percussion music for
lessons that I am giving, and if someone could help me disect some code this
would be great:
\new DrumStaff <<
\new DrumVoice = "1" { s1 *2 }
\new DrumVoice = "2" { s1 *2 }
\drummode {
bd4 sn4 bd4 sn4
<<
{ \repeat unfold 16 hh16 }
\\
{ bd4 sn4 bd4 sn4 }
>>
}
>>
here is what I understand: DrumStaff creates a staff, thats simple. drummode
initiates the acceptance of sn bd hh etc. as valid input. I also understand
that there is a measure of alternating bd/sn hits for 4 beats before the
'polyphonic' measures. I understand that the polyphonic measure uses two
'voices, one that is just the hh and one that is the bd and sn.
Here is what I don't understand: the creation of \new DrumVoice = "1" { s1
*2 }. Why do i need to create new drum voices. And if im not referencing
them later, how does the code know which one is which. Are "1" and "2"
simply names, or do they have do do with stem directions, or what? and what
in heck does {s1 *2} mean?
Thank you for your help. I am new at using lilypad, i stumble across it and
don't know anyone else who can help me. This is the first time I've used
this mailing list so even if you cant help me, letting me know that I've
succeeded in asking for help would be nice. thanks.
