music21 v9

Music21 v9 (June 2023) is the latest release of music21, a toolkit for computational music research.

Version 9 contains about 600 new commits and features from the version 8 release from September 2022. It is the latest and best release in the industry standard toolkit for doing music research and composition ("traditional" computation and AI/ML) with musical scores.

As a new Version X release, music21 gains a lot of its power with a few non-backwards compatible changes that make the system easier to use, faster, and more up to date. People using music21 in existing environments should read the change logs to make sure their systems work with it before upgrading.

A big change in music21 is that v9 is compatible with Python 3.10 and 3.11 only. The version 9 release will be updated to be compatible with at least Python 3.12 when it is released. Users on Python 3.8 and 3.9 should stick with v8 and those on older versions should look at the README to see what version will be installed for their systems.

Two weeks from the release of version 9 (July 1, 2023), Michael Asato Cuthbert, the lead developer of music21 will take a 6-12-month sabbatical from monitoring the mailing list, answering questions/issues, and merging PRs in order to focus on what he does best and what is best for the community: developing core parts of the system and documenting what already exists. Working with the user community has been amazing, but given that he only has about 10-15 hours per week to devote to the project, it often means deviating from efforts that help a large number of people to instead work through PRs and issues that are important to a smaller community. This news will probably not be welcomed by some, but the results should be better for the larger community.

What's Changed

• Music21 v9 is for Python 3.10 and 3.11 only and uses tools and speedups only available to those versions. Music21 drops its prior policy of supporting previous 3 versions and now supports the latest 2 versions only (to improve developer experience).
• Notebook/Jupyter: All pages are now shown on .show(). Compatible with Jupyter 7.0beta and JupyterLab. MIDI improvements (@​mscuthbert in cuthbertLab/music21#1592)
• Added to corpus: (1) Queen Liliuokalani’s Aloha Oe, (2) J.R. Johnson’s Lift Every Voice And Sing (3) Vincente Lusitano’s madrigal Allor che Ignuda – part of a larger project to make the music21 corpus more representative.
• Lots more typing! Use music21 in a modern IDE to see it. Uses Python 3.10 TypeGuards. Add common.classTools.holdsType([‘a’, ‘b’], str) which asserts that everything in a collection has the same type. (@​mscuthbert in cuthbertLab/music21#1447). converter and corpus are fully typed.
• Docs! Documentation of equality explained better. braille, corpus, converter much improved. (1) Much better aesthetics and utility @​mscuthbert in cuthbertLab/music21#1455 and #1452). (2) Add “developerReference/startingOver” – mistakes made in designing music21 that are too late to fix, but the next generation of software should not emulate. (3) add docs about abcFormat support (@​mscuthbert in cuthbertLab/music21#1484). (4) coreInsert (@​mscuthbert in cuthbertLab/music21#1549). (5) layout (@​mscuthbert in cuthbertLab/music21#1554). (6) clercqTemperley (RS100 dataset) format (#1558)
• RomanText and related formats: (1) Repeats in RT and TSV are improved (@​malcolmsailor in cuthbertLab/music21#1434, cuthbertLab/music21#1435, cuthbertLab/music21#1503) (2) anacrusis support (@​mscuthbert in cuthbertLab/music21#1532) (3) measure numbers on ClercqTemperley (@​mscuthbert in cuthbertLab/music21#1558)
• harmony: (1) RomanNumerals and ChordSymbols with front accidentals (flat II, sharp IV, etc.) now take their 7ths, 9ths, etc. from the underlying keys (@​mscuthbert w/ thanks to @​malcolmsailor in cuthbertLab/music21#1439), (2) RomanNumeral’s writeAsChord works properly (@​mscuthbert in cuthbertLab/music21#1445) and (3) transpose properly (@​malcolmsailor in cuthbertLab/music21#1414). (4) roman.RomanNumeral(2, ‘C’) will now give d-minor, not d-major (@​jacobtylerwalls in cuthbertLab/music21#1481), (5) preferSecondaryDominants implements V/x (@​MarkGotham in cuthbertLab/music21#796).
• MusicXML improvements: (1) TempoText is exported (@​gregchapman-dev in cuthbertLab/music21#1437) (2) harmony/numeral figures are MusicXML 4.0 compatible (@​mscuthbert in cuthbertLab/music21#1445) (3) Preserve multiple fingerings on chords in musicxml import (@​jacobtylerwalls in cuthbertLab/music21#1475) (4) Translate "implicit" attribute of MusicXML measures (@​jacobtylerwalls in cuthbertLab/music21#1493) (5) Synchronize Measure IDs on Musicxml out (@​rigaux in cuthbertLab/music21#1490) (6) MusicXML sound tag finds metronome marks (@​TimFelixBeyer in cuthbertLab/music21#1579) (7) Add MusicXML security warning (@​mscuthbert in cuthbertLab/music21#1584)
• Speed/Performance improvements on (1) deepcopy (@​mscuthbert in cuthbertLab/music21#1464) (2) ABC (@​mscuthbert in cuthbertLab/music21#1461) (3) LanguageDetector (@​mscuthbert in cuthbertLab/music21#1456) (4) quantize() (@​TimFelixBeyer in cuthbertLab/music21#1594) (5) use deques instead of pop(0) #1466, (6) searching/MetadataBundles cache in tests (@​mscuthbert in cuthbertLab/music21#1511) (7) findGaps() on gapless streams (@​jacobtylerwalls in cuthbertLab/music21#1515) (8) ChordSymbols (@​jacobtylerwalls in cuthbertLab/music21#1527)
• Braille – add segment.BrailleElementGrouping. Good amount of refactoring. (@​mscuthbert in #1495)
• Converter/Corpus: converter.toData – like .write or .show but gives the raw data as a string or byte by @​mscuthbert in cuthbertLab/music21#1451
• Frozen/Immutable objects can be created now; this will allow for creating, for instance, one default 4/4 meter that cannot be changed but used as a default in many places. common.FrozenObject and duration.FrozenDuration (@​mscuthbert in cuthbertLab/music21#1460)
• New subConverters register above default subConverters, so it is now possible to develop a subConverter like Greg’s converter21 project that handles a format music21 supports but do it differently or better. (@​mscuthbert in cuthbertLab/music21#1520)
• Ornaments/Expressions (all by @​gregchapman-dev) – (1) ornament accidentals have a great new system and are aware of their measure and key context (cuthbertLab/music21#1545) (2) Mordents get placement like Turn and Trill (cuthbertLab/music21#1516) (3) Support for delayed turns (cuthbertLab/music21#1533)
• Spanners: (1) Spanner.fill() – say you’ve set a slur to just include the first and last notes. .fill() will find all the intermediate notes. (@​gregchapman-dev in cuthbertLab/music21#1486) (2) spanner.SpannerAnchor class allows a spanner to start and stop at a point where there is no other Music21Object at the offset (like a whole note crescendo that begins on beat 2 and ends on beat 3) (@​gregchapman-dev in cuthbertLab/music21#1479). (3) Guitar: Hammer-on and Pull-off as Spanners (@​louisbigo in cuthbertLab/music21#1142)
• Streams – (1) new module stream.tools and stream.tools.removeDuplicates (e.g. keys, clefs, by @​MarkGotham in cuthbertLab/music21#1454) . (2) stream.makeNotation.saveAccidentalDisplayStatus() context manager for restoring pitches’ accidentalDisplayStatus after a manipulation (like transposition by octave) @​gregchapman-dev. (3) stream.makeNotation.makeOrnamentalAccidentals (#1545)
• Percussion: (1) Implement useful PercussionChord.pitches property (@​jacobtylerwalls in cuthbertLab/music21#1547), (2) Ignore Unpitched objects in key analysis (@​jacobtylerwalls in cuthbertLab/music21#1543, (3) Search support (@​mscuthbert in cuthbertLab/music21#1597)
• MIDI: (1) Minimize gaps produced by quantization algorithm (@​jacobtylerwalls in cuthbertLab/music21#1540) (2) fix jupyter/colab MIDI (@​mscuthbert in cuthbertLab/music21#1565) (3) Increase default MIDI ticksPerQuarter for higher accuracy of tuplets (@​TimFelixBeyer in cuthbertLab/music21#1577)
• ABC: set version from I:abc-version information (@​mscuthbert in cuthbertLab/music21#1589)
• pitch module gets: isValidAccidentalName, standardizeAccidentalName.

Bug fixes

• Avoid creating duplicative ChordStepModifications (@​jacobtylerwalls in cuthbertLab/music21#1509)
• Zero quarterLengths will not be represented as Fraction(0, 1)
• MIDI: (1) Don't set status byte on Meta Message (@​TimFelixBeyer in cuthbertLab/music21#1575) (2) unknown meta message still parses (@​TimFelixBeyer in cuthbertLab/music21#1573)
• Fix stripTies when accidentals are natural & none (@​TimFelixBeyer in cuthbertLab/music21#1556)
• Scores could previously change after .write()(@​TimFelixBeyer in cuthbertLab/music21#1560)
