Hi Dan, Neil, et al.:

Does the following help?
SoloVoice is a kind of Voice. UpperVoice and LowerVoice are kinds of SoloVoice.

That's [relatively] self-evident. What isn't crystal clear — either in my mind, or (IMO) in the documentation — is why the following wouldn't work (or, perhaps better put, *what* wouldn't work if the following were used):

\context {
 \name SoloVoice
 %% \alias "Voice"

or alternatively

\context {
 %% \Voice
 \name SoloVoice
 \alias Voice

If I understand parser.yy and files, it looks like "\Voice" starts you off with a copy of the previously defined Voice settings. If "\Voice" is absent, you start from scratch.

The context settings are saved by name. If you do not change the name, the modified settings replace the previous settings of the \Voice context. If you change the name, a new kind of context is created.

I haven't looked into \alias.
