'''
The most important method call for corpus.
Similar to the :meth:`~music21.converter.parse` method of converter
(which takes in a filepath on the local hard drive), this method
searches the corpus (including the virtual corpus) for a work fitting
the workName description and returns a :class:`music21.stream.Stream`.
If `movementNumber` is defined, and a movement is included in the
corpus, that movement will be returned.
If `number` is defined, and the work is a collection with multiple
components, that work number will be returned. For instance, some of
our ABC documents contain dozens of folk songs within a single file.
Advanced: if `forceSource` is True, the original file will always be
loaded freshly and pickled (e.g., pre-parsed) files will be ignored.
This should not be needed if the file has been changed, since the
filetime of the file and the filetime of the pickled version are
compared. But it might be needed if the music21 parsing routine has
changed.
Example, get a chorale by Bach. Note that the source type does not
need to be specified, nor does the name Bach even (since it's the only
piece with the title BWV 66.6)
>>> from music21 import corpus
>>> bachChorale = corpus.Corpus.parse('bwv66.6')
>>> len(bachChorale.parts)
4
After parsing, the file path within the corpus is stored as
``.corpusFilePath``
>>> bachChorale.corpusFilepath
u'bach/bwv66.6.mxl'
