NotationModel package contains modules for the purposes of defining a model of musical notations.
The types contained herein extend the structures defined in the dn-m/Music package, providing a rich context for abstract musical information so that it can be represented within a variety of notational media. This package remains agnostic to the concrete rendering backend.
For work on the graphical representation of music in Swift, see dn-m/NotationView.
SpelledPitch module exposes structures for describing abstract pitches (e.g., what you get if you press a key on a MIDI keyboard) with letter names and accidentals. This is done in a progressively-disclosed and type-safe manner: it is easy to describe common pitch scenarios, linearly more difficult to describe more-rare pitch scenarios, and it is impossible to describe logically-invalid pitch scenarios.
Pitch.Spelling structure provides a model of the Helmholtz-Ellis notation system. This notation system scales elegantly from the Western common practice twelve-note equal division of the octave tuning system to that of high-limit just intonation. This system is represented in the SMuFL specification, making a mapping of these structures into a rendering context as seamless as possible.
SpelledRhythm module defines models of beams, ties, and dots.
Defines a model for positioning values onto two-dimensional plots.
PlotModel, incorporating the concept of clefs, noteheads, accidentals, etc.
Work on this package requires Swift 4.2.
