technically. YES
 
a class name is a URI and a uri can contain colons (like http:// you
notice the colon ?)
 
but you have to place them behind a normal uri, like
 
http://www.thrupoint.net/MusicStyles:Electronic
 
Now perhaps some applications will "throw up" when they see it but it
could work. Especially keep in mind, that colons are often used to
abbreviate namespaces, like "rdf:label" so a parser might get dizzy.
 
 
 
 
And another thing, if that example is serious:
the example imlies that DeepHouse is a subclass of House and Electronic
 
DON'T DO HIERARCHY
 
guys who know about ontology theory (and f.e. the dewey decimal system)
are getting ecstatic when they try to put everything in a single
hierarchy, but that is normally not very useful to do. You always will
have the one class that does not fit in a hierarchy, because it is
subclass of two.
 
What I mean is that, you will have endless discussions with audiophiles,
if DeepHouse is really electronic or more HipHop or DeathMetal
influenced etc. (haha). Seriously, I would do something like:
 
http://www.thrupoint.net/MusicStyles#Electronic 
http://www.thrupoint.net/MusicStyles#House
http://www.thrupoint.net/MusicStyles#DeepHouse
 
and then
http://www.thrupoint.net/MusicStyles#DeepHouse
rdfs:subClassOf 
http://www.thrupoint.net/MusicStyles#House .
 
(or whatever rdfs does this, the essence is that you can do a fine
hierarchy with RDFS subclasses.)
 
House and Electronic are different things and it is wise to have
different URLs.
 
btw: http://www.monochrom.at/electronitsch/ is the right way to spell it
:-)
 
 
hope that was useful somehow,

Can class names include colons? 

i.e. <Music:Electronic:House:DeepHouse>
