Concept connections
Pitch classOne of the twelve pitches from C to B, independent of octave. Transposition rotates its position around the chromatic circle.PointA relative pitch position measured in semitone steps. Anchor it to a note to obtain an absolute pitch; keep it unanchored to compare transposed shapes.IntervalA signed semitone distance between two pitches. Moving both endpoints together preserves the interval.Note setA group of concrete MIDI pitches with octaves. It specifies one voicing and can be reduced to pitch classes or a rootless point shape.Note RangeThe span between a lowest and highest MIDI note. It describes a register boundary, not every note inside it.Note Set CollectionAn unordered collection of unique note sets
