About ShakuViewer

ShakuViewer is a program that displays music scores in shakuhachi notation. Although most of the conversion is done automatically, users can control the process through a procedure called score annotation, by adding conversion indications (e.g., for alternative fingering) into the input files.

ShakuViewer reads Western-music notation scores in MusicXML format, for instance created by MuseScore. An example of such a score, Amazing Grace, is shown below as displayed in MuseScore and ShakuViewer. Another ShakuViewer screenshot shows the first page of the piece called Haru no umi (Spring Sea).

MuseScore plugin

MuseScore is a free music composition and notation software, which can be used not only to input music notation, but also to import other file formats such as MIDI or even PDF. To make it easier to use ShakuViewer from MuseScore, based on a suggestion by Hiroshi Tachibana, I created a MuseScore plugin so that the currently opened score in MuseScore can be displayed in ShakuViewer without any other actions required from the user. For more information, check out the plugin page on the MuseScore website.
