在python安装 music21后，需要关联 musescore 或 lilypond 才能可以用图形化的形式看到 乐谱。
因此 在安装 music21后，需要配置环境变量
首先、 通过 导入music21：
from music21 import *
然后，查看环境变量有哪些。
>>>environment.keys() [‘directoryScratch‘, ‘lilypondPath‘, ‘lilypondVersion‘, ‘lilypondFormat‘, ‘lilypondBackend‘,
‘musicxmlPath‘, ‘midiPath‘, ‘graphicsPath‘, ‘vectorPath‘, ‘pdfPath‘, ‘braillePath‘, ‘musescoreDirectPNGPath‘,
‘showFormat‘, ‘writeFormat‘, ‘ipythonShowFormat‘, ‘autoDownload‘, ‘debug‘, ‘warnings‘, ‘localCorpusSettings‘,
‘localCorporaSettings‘, ‘manualCoreCorpusPath‘, ‘localCorpusPath‘]
或者是
>>> us = environment.UserSettings()
>>> us.keys()
[‘directoryScratch‘, ‘lilypondPath‘, ‘lilypondVersion‘, ‘lilypondFormat‘, ‘lilypondBackend‘, ‘musicxmlPath‘,
‘midiPath‘, ‘graphicsPath‘, ‘vectorPath‘, ‘pdfPath‘, ‘braillePath‘, ‘musescoreDirectPNGPath‘, ‘showFormat‘,
‘writeFormat‘, ‘ipythonShowFormat‘, ‘autoDownload‘, ‘debug‘, ‘warnings‘, ‘localCorpusSettings‘,
‘localCorporaSettings‘, ‘manualCoreCorpusPath‘, ‘localCorpusPath‘]
后续统一使用后者进行配置。
对于 lilypond的配置（路径请自行编写）：
us[‘lilypondPath‘] = ‘C:/Program Files (x86)/LilyPond/usr/bin/lilypond.exe‘
对于 musescore的配置：
us[‘musescoreDirectPNGPath‘] = "C:/Program Files (x86)/MuseScore 2/bin/MuseScore.exe"
us[‘musicxmlPath‘] = "C:/Program Files (x86)/MuseScore 2/bin/MuseScore.exe"
如果 keys()里面没有 相关配置，可以先set出相关配置项。
environment.set("musescoreDirectPNGPath", "C:/Program Files (x86)/MuseScore 2/bin/MuseScore.exe")
environment.set("musicxmlPath", "C:/Program Files (x86)/MuseScore 2/bin/MuseScore.exe")
