A new version of
has been released, the first
public release since January. This release focuses primarily
on speed and stability improvements so it is worth an upgrade even
if none of the new features is of use to you. A summary of
- Many improvements to Layout -- information soon, but pixel level positioning of measures can now be extracted from MusicXML files.
- Chordify addPartIdAsGroup=True works better.
- Better triplet handling in Humdrum SpineParser.
- Some .nwc files (not just .nwctxt) files can now be parsed.
- Improvements for PartStaffs (Piano scores, etc.)
- .transpose works on Key objects.

Version 1.4.0 of
music21 is released. This is a minor release on the
outside, but incorporates a number of changes that will let us do
more substantial changes in the upcoming next release. Among
the most substantial changes that people will notice are:
- Better documentation and more chapters in the User's Guide
- Ability to import Capella XML (.capx) files
- Articulations, grace notes, crescendo, and diminuendo now import in ABC (and the code is in place to bring in many more !exclamation! tags). Thanks to Dylan Nagler, Harvard Research Partner for the code.
- analysis.neoRiemannian allows for analyzing the effect of smooth voice leading on chords. Thanks to Maura Church, Harvard Research Partner for the code.
- Humdrum parsing improvements, including comments and better handling of multiple voices and importing of instruments.
- Lilypond now supports different numbers of stafflines in output
- Percussion support for MIDI and the basics of an Unpitched object type. Thanks to Ben Houge for commits.
- Improvements to chords, including a better .root() algorithm for incomplete chords, geometricNormalForm -- implements Dmitri Tymoczko's algorithm for normal form.
- More useful errors when parsing incorrect or unsupported features in several formats.
- New files in the corpus, including many 14th century scores, and the 2nd movement of Clara Schumann's Piano Trio. Female composers are hugely underrepresented in computer-readable music repertories (we couldn't find any substantial piece that was available), so we're proud to add an important work (known to many of us from the Norton Anthology of Western Music) by a great compose.
- Serialization of Streams via Pickle is much better tested and works even on large scores. See the freezeThaw module. If you're going to work with the same pieces over and over again, freeze them once and you'll load them over 3x as fast the next time you need them.
- MusicXML improvements: bowing marks are now supported as are pizzicato, etc. A bug on piano staves where one used multiple voices but the other did not has been fixed.
- Improvements to the harmony module. Thanks to Beth Hadley, MIT Undergraduate Research Assistant.
- Big speed increase on startup for people who have installed additional modules: numpy, scipy, and matplotlib are only loaded when first needed.
The next release will include support for virtualenv installs (I know people have been waiting for it, but this release included switching the entire development/commit platform, so we didn't want to change too much at once) and will have optional support for Rational number durations and offsets for perfect work with complex tuplets, etc.
In the meantime, I've been using music21 to explore similarity in fourteenth-century music to great success, so I hope to be able to share my own experiences as a user, not just a developer, of the toolkit very soon. -- Michael

I was emailing back and forth with a student research assistant
about some algebraic properties
of adding, subtracting, multiplying, and dividing intervals, and
I thought that I might share the email (in slightly revised form)
with the Net. I would be very surprised if this hasn't been
written up already by someone else, but the only things I could
find quickly about interval multiplication was all in the
12-tone/serial usage, which is less interesting to me

Reward all your servants with everlasting tenure -- Lord hear our prayer
Deliver our souls from indecipherable tropes, and the souls of those who transcribe ars subtillior,
who search in archives, and read clerical shorthand -- Lord hear our prayer
Give and preserve the fragments not yet found,
Yield to us productivity in our sabbaticals,
Grant three beats of rest to all perfect semibreves pausae
Never causing our Finales or Sibeliuses to think of imperfecting them,
That it may please You to hear us and our editions,
Jesus, Son of the Living God -- Lord hear our prayer
Lamb of God, who takes away the sins of transcription -- Spare us, O Lord!
Lamb of God, who takes away the sins of musicology -- Spare us, O Lord!
Lamb of God, who takes away the sins of scholarship -- Grant us thy peace.
Christ, hear us,

Lord, have mercy on us,
Christ, have mercy on us,
Lord, have mercy on us,
Cuthbert received his A.B. summa cum laude, A.M. and Ph.D. degrees from Harvard University. He spent 2004-05 at the American Academy as a Rome Prize winner in Medieval Studies, 2009-10 as Fellow at Harvard's Villa I Tatti Center for Italian Renaissance Studies in Florence, and will be a Fellow at the Radcliffe Institute in 2012-13. Prior to coming to MIT, Cuthbert was Visiting Assistant Professor on the faculties of Smith and Mount Holyoke Colleges. His teaching includes early music, music since 1900, and music theory.
Cuthbert has worked extensively on computer-aided musical analysis, fourteenth-century music, and the music of the past forty years. He is creator and principal investigator of the music21 project. He has lectured and published on fragments and palimpsests of the late Middle Ages, set analysis of Sub-Saharan African Rhythm, Minimalism, and the music of John Zorn.
Cuthbert is writing a book on Italian sacred music from the arrival of the Black Death to the end of the Great Schism.
