Description: Provides a music notation syntax and a collection of music
        programming functions for generating, manipulating, organizing,
        and analyzing musical information in R. Music syntax can be
        entered directly in character strings, for example to quickly
        transcribe short pieces of music. The package contains
        functions for directly performing various mathematical, logical
        and organizational operations and musical transformations on
        special object classes that facilitate working with music data
        and notation. The same music data can be organized in tidy data
        frames for a familiar and powerful approach to the analysis of
        large amounts of structured music data. Functions are available
        for mapping seamlessly between these formats and their
        representations of musical information. The package also
        provides an API to 'LilyPond' (<https://lilypond.org/>) for
        transcribing musical representations in R into tablature
        ("tabs") and sheet music. 'LilyPond' is open source music
        engraving software for generating high quality sheet music
        based on markup syntax. The package generates 'LilyPond' files
        from R code and can pass them to the 'LilyPond' command line
        interface to be rendered into sheet music PDF files or inserted
        into R markdown documents. The package offers nominal MIDI file
        output support in conjunction with rendering sheet music. The
        package can read MIDI files and attempts to structure the MIDI
        data to integrate as best as possible with the data structures
        and functionality found throughout the package.
