The tools used for the job.
The Genetic Sandbox
A web-based application that can be used to help organize writing layers. This essentially separates each symbol on the page into its own object that can be highlighted and differentiated. This tool encourages users to embrace collaboration and follow similar methods to digital humanities.
MusicDiff
A software used to compare two different pieces of sheet music and relay the differences to the user. It does this by providing color coordinated notes and descriptive text that describes the differences between the two scores you provided it with.
MEI
Music Encoding Initiative or MEI is an open source software used to integrate music notation and XML computer language to easily analyze and deconstruct musical phrases. In other words, MEI is a way of encoding music digitally so that both the computer and user can differentiate the different parts of music scores.
(They could be helpful for other digital humanities projects. More specifically, “The Genetic Sandbox” could be helpful for other digital humanities projects, but the other tools listed may be too specific to music composition, and may not be helpful in other digital humanities projects that don’t involve music composition)
