It would seem that you associate the term "pitch" with physical
frequency. That is not how LilyPond uses the term (though indeed the
respective "music glossary" entry leaves something to be desired
regarding clearing that up).
<URL:http://www.lilypond.org/doc/v2.16/Documentation/notation/pitches>
A "note" is more than a pitch: it has duration, articulations, etc.
Indeed, if I ask the Scheme sandbox:
$ lilypond scheme-sandbox
GNU LilyPond 2.17.12
Processing `/usr/local/share/lilypond/2.17.12/ly/scheme-sandbox.ly'
Parsing...
guile> #{ c #}
#<Pitch c >
guile> #{ c4 #}
#<Prob: Music C++: Music((duration . #<Duration 4 >) (pitch . #<Pitch c >)
(origin . #<location <string>:2:2>))((display-methods #<procedure #f (note
parser)>) (name . NoteEvent) (iterator-ctor . #<primitive-procedure
ly:rhythmic-music-iterator::constructor>) (types general-music event note-event
rhythmic-event melodic-event)) >
guile>
It also considers "c" just a pitch (composed from octave, notename and
alteration), while "c4" is a complete note.
