    Proposed CPAN Module: Tk::Canvas::Music

    This module will create a Tk::Widget which ISA Tk::Canvas. It will
    export functions that paint scores, notes, key signatures, time
    signatures, tempo and other text, bar lines, a cursor/caret, ledger
    lines, and so on. It will have a set of default bindings that allow
    input from the keyboard. The key-mapping may be redefined at any time.
      There will be a Read-Only version with none of the input bindings, for
    display purposes or for the perl community to add their own bindings to.

    A module like this can allow the printing of musical score, the input of
    music in a conventional manner, or even the export of music to midi,
    MusicXML, or any other form of storage. The Music::Note module will be
      used to create a new Note module to represent the notes as objects.
    The new Note module is necessary so that notes may have a length
    property and may be rests. A Staff module will allow representation of
    staves as objects. paint()ing the Staff will automatically paint() all
    of the notes that belong to it, using the treble clef by default, but
    adjusting the vertical position appropriately for any clef. Since the
    Music::Note module is used, transposition will be easy, thus a
    particular staff of a composition may be isolated and printed for Bb or
    Eb (or any other) instruments.

    This module is at the idea stage, will be written in perl, and will have
    the standard perl license.

    So, what do you think?... feedback please.
