The most powerful and easy to use tool is the :func:`~music21.converter.parse` function. Simply provide a filename, URL, or text string and, if the format is supported, a :class:`~music21.stream.Score` will be returned. This is the most general, public interface for all formats. Programmers adding their own formats to the system should provide an interface here to their own parsers (such as humdrum, musicxml, etc.) The second and subsequent times that a file is loaded it will likely be much faster since we store a parsed version of each file as a "pickle" object in the temp folder on the disk. >>> #_DOCS_SHOW s = converter.parse('D:/myDocs/schubert.krn') >>> s = converter.parse(humdrum.testFiles.schubert) #_DOCS_HIDE >>> s ) annotations)deque) responsesN)isclose) subConverters) museScore)_version)common) environment) exceptions21)metadata)musedata)stream)bundles)base)ArchiveManagerArchiveManagerException ConverterConverterExceptionConverterFileException PickleFilterPickleFilterExceptionfreeze freezeStrrparse parseData parseFileparseURLregisterSubConverterresetSubConvertersrthawthawStrunregisterSubConverter converter _StrOrBytes)boundceZdZdS)rN__name__ __module__ __qualname__/Users/tedpeters/Documents/Projects/Claude Projects/Misc Tools/notename-sheets/.venv/lib/python3.11/site-packages/music21/converter/__init__.pyrraDr-rceZdZdS)rNr(r,r-r.rrer/r-rceZdZdS)rNr(r,r-r.rrir/r-rceZdZdS)rNr(r,r-r.rrmr/r-rcBeZdZdZdddZddZdd Zddd Z dddZdS)raR Before opening a file path, this class can check if this is an archived file collection, such as a .zip or .mxl file.
