Necessary dialogs, it’s unlikely they could be as streamlined as Like setting and changing key or time signatures, adding articulations,Įtc? While traditional notation program may set up keyboard shortcutsįor some of these operations, or provide keyboard control for the Note entry, after all, is only part of the equation. Still a lot of work, and I suspect the results would still proveĬumbersome for most blind users to deal with, just as I hear many reportĪbout trying to use Sibelius with its various accessibility options. It’s logistically feasible if you have the skills. Whereas taking anĮxisting notation program and doctoring it up to be more accessible is Since music21 does most of the hard work for you. Developing such a program really would *not* be difficult at all, I keep emphasizing the phrase “trivially simple”, and I really do mean Input and output and then calling other programs to convert this to It would beįully keyboard controllable and screenreader friendly from the beginningīecause the program would really be doing nothing but dealing with text Hands) to get something simple but effective up and running. Just a matter of a few weeks (for someone with enough time on their Like, not years or even months, but maybe I am confident that using music21, one could write such a program in aįairly short amount of time. It would mostly be about accepting typed inputĪnd feeding it to the music21 system to build an internal representationįrom, and conversely, reading the score back in English from that So the program I am talking about would not have to deal with graphical Trivially simple to export this internal representation to MusicXML orĪBC, at which point another program could render it as standard notation.
Unless you write your own language-aware editor). Very difficult to pull off in a system based on ABC or Mup or whatever “play current measure” or “play current staff” or whatever (all things Via MIDI – and that includes a “play from cursor position” as well as Trivially simple to playback that internal representation of the music Mode, or it could be made interactive, so you’d cursor through the scoreĪnd it would read what was under the cursor. This read-back could be in a plain read-entire-score-aloud-all-at-once
Plain English, “E quarter D quarter C quarter…” or “Quarter E D C D EĮ Half D…” or however the program designer decided it should read. Then be trivially simple for the program to read your score back in Importantly, to build up its own internal representation of the score You to type that, have it play back each note as you typed it, and most It would be trivially simple for a music21 program to allow Input system, where Mary Had A Little Lamb is represented as 4 E D C D EĮ 2 E? I’m not saying I’d ever care to read that, but that’s what is Well, isn’t this really just a fancy way of saying we’ve defined a text Programs, except the specific numbers and letters you press to setĭuration and enter notes differ from program to program. That’s more or less *exactly* how it works in all of those Type E to enter that pitch as a half noteĪnd so on. Type E D C D E E to enter those pitches as quarter notes So forĮxample, Mary Had A Little Lamb might be entered like this: You press the new number, then enter more pitches, and so on. Where you first press a number to set the current duration, then start For example,įinale, Sibelius, MuseScore, and Lime all support a note entry system See the text – only the notation that results from typing. Most notation programs have a keyboard-based input system that really isĮssentially just typing text. Here is something I posted to the MENVI mailing list on this subject: We welcome feedback on how you think such a program should work. It’s mostly just a matter of designing the interface.
#MUSIC21 HOW TO EXPORT TO MUSICXML FULL#
This prototype had limited editing capabilities but full and robust browsing capabilities featuring use of cursor keys to navigatw a score by element, by measure, by voice, by staff, etc.Įxtending this to provide more editing capabilities should not be very difficult because, again, music21 really does all the difficult parts already. So a program written using music21 would need only provide keyboard controls for accessing these functions.Ī prototype for such a program was developed in July 2013 as part of Music Hack Day 2013. This toolkit provides routines that can read a MusicXML file and build a set of data structures to represent a score, routines that can process those data structures in various ways including adding and deleting notes and other elements, and routines that can write the data structures back out to MusicXML. I have come to be convinced that a simple but useful and fully accessible notation editor could be developed with surprisingly little effort using a Python-based music programming toolkit called music21.
