Note Range
The span between a lowest and highest MIDI note. It describes a register boundary, not every note inside it.

Select offsets from the lowest note. Transposition moves the MIDI notes and their pitch classes, while the relative point shape remains unchanged.

Concept connections
Pitch-class setA selection of the twelve pitch classes, independent of octave and order. It says which pitches are present without choosing a chord root or voicing.Point SetA rootless arrangement of semitone offsets from the lowest note. Its shape stays the same when a MIDI voicing is transposed.ScoreA polyphonic texture — several voices (temporalized lines / tracks) sounding at once over a shared timeline. The simultaneous counterpart of a note-set: where a note-set stacks single notes into a chord, a score stacks whole lines. Its `groupOf` is note-sequence. Collapse the voices at each instant and you get a chord progression (note-set-sequence) — the resulting chord qualities of the simultaneous notes; conversely, a chord progression can be voice-led into a score. Strip pitch and it becomes a point-score (key-independent counterpoint).Note Set CollectionAn unordered collection of unique note setsNote Set Sequence CollectionAn unordered collection of chord progressions — e.g. a songbook of changes or a library of progressions. A meta-group: a group of groups, whose `groupOf` is note-set-sequence (one level up from a note-set-collection).Note SpaceA 128-bin distribution over MIDI notes. Counts or weights retain register and repeated occurrences.
