"Description": "Provides a music notation syntax and a collection of music\nprogramming functions for generating, manipulating, organizing,\nand analyzing musical information in R. Music syntax can be\nentered directly in character strings, for example to quickly\ntranscribe short pieces of music. The package contains\nfunctions for directly performing various mathematical, logical\nand organizational operations and musical transformations on\nspecial object classes that facilitate working with music data\nand notation. The same music data can be organized in tidy data\nframes for a familiar and powerful approach to the analysis of\nlarge amounts of structured music data. Functions are available\nfor mapping seamlessly between these formats and their\nrepresentations of musical information. The package also\nprovides an API to 'LilyPond' () for\ntranscribing musical representations in R into tablature\n(\"tabs\") and sheet music. 'LilyPond' is open source music\nengraving software for generating high quality sheet music\nbased on markup syntax. The package generates 'LilyPond' files\nfrom R code and can pass them to the 'LilyPond' command line\ninterface to be rendered into sheet music PDF files or inserted\ninto R markdown documents. The package offers nominal MIDI file\noutput support in conjunction with rendering sheet music. The\npackage can read MIDI files and attempts to structure the MIDI\ndata to integrate as best as possible with the data structures\nand functionality found throughout the package.",
