Likely, this should have been "Clarinet in Bb" where the small "b" is for
"flat" (i.e. a clarinet in B flat, where a "c" on the clarinet will sound
as "b flat" in concert pitch).

Assuming that "clarinetNotes" contains the notes:
If the part contains the notes in _concert_ pitch, you use the:
\transposition bes {% make MIDI sound right
\transpose bes c { % transpose to clarinet notation
<<
\global
\clarinetNotes
>>
}
}
If the part contains the notes as transposed for clarinet, you use:
\transposition bes { % make MIDI sound right
\transpose bes c { % transpose to clarinet notation
<<
\global
\transpose c bes { % transpose to concert pitch
\clarinetNotes
}
>>
}
}
}
and the MIDI will sound OK while the PDF will show the part transposed for
clarinet.
[In the above, "\global" contains e.g. the actual "\key" (i.e. in concert
pitch). For example, if the piece is in G minor, the part for clarinet in Bb
will be written in A minor.]
