Bridges

Converting into another concept may need context this value does not carry (a root, an octave, a key). Where it is missing the library assumes a default and says so; where a step drops information it is listed.

• Note distribution · MIDI : weight pairs

  lossy
  60:1,62:1,64:1,65:1,67:1

  Path melody → note-space

  • Drops order, duration, rests. Counts how often each MIDI note occurs (weighted by occurrence, not duration).

• Note set · Letter names

  lossy
  C4-D4-E4-F4-G4

  Path melody → note-set

  • Drops order, duration, rests, repetition. A melody collapses to the unordered, untimed set of pitches it uses.

• Point melody · Point : beats

  lossy
  0:1,2:1,4:1,5:1,7:1

  Path melody → point-melody

  • Drops root, register. A melody loses its absolute pitch, keeping rhythm and relative shape.

• Rhythm · Beats

  lossy
  1,1,1,1,1

  Path melody → rhythm

  • Drops pitch. A melody's timing alone — its durations and rests, with the pitches removed.

• Scale degrees · Jianpu (numbered notation)

  lossy
  1=C 1 2 3 4 5

  Path melody → scale-degrees · needs key, octave

  • Assumed key C major. No key was given, so C major is used.
  • Assumed octave 4. No octave was given, so octave 4 is used.
  • Drops timing, rests. Each note's distance from the key's tonic (in the context octave) as a degree; rests and durations are dropped.

• Score (voices) · Voices: pipe-separated melodies in beats

  lossy
  60:1,62:1,64:1,65:1,67:1

  Path melody → score · needs key, meter

  • Assumed key C major. No key was given, so C major is used.
  • Assumed meter 4/4. No meter was given, so 4/4 is used: one cycle is one 4/4 bar.
  • Drops metadata. Voices notation writes the notes only: key, meter, tempo, title and chords are dropped.

• Grid position · Cells col,row (optional layout@origin: prefix)

  lossy
  aura@C3:3,0 2,2 4,0 2,3 4,1

  Path melody → note-set → grid-position · needs layout, root

  • Assumed layout aura. No layout was given, so positions are read on the aura layout.
  • Assumed root C3. No root was given, so the value sounds above C3.
  • Drops order, duration, rests, repetition. A melody collapses to the unordered, untimed set of pitches it uses.
  • Drops alternative positions. C4 has 2 positions, E4 has 2 positions, G4 has 2 positions on aura; the one nearest (0, 0) is kept.

• Pitch-class distribution · Twelve weights

  lossy
  1,0,1,0,1,1,0,1,0,0,0,0

  Path melody → note-space → pc-space

  • Drops order, duration, rests. Counts how often each MIDI note occurs (weighted by occurrence, not duration).
  • Drops octave, register. Folds 128 MIDI bins into 12 pitch-class bins, keeping the weights.

• Pitch-class set · Pitch-class numbers

  lossy
  0-2-4-5-7

  Path melody → note-set → pc-set

  • Drops order, duration, rests, repetition. A melody collapses to the unordered, untimed set of pitches it uses.
  • Drops octave, register, duplication, order. A note set collapses to the unordered set of its pitch classes.

• Point set · Semitone offsets

  lossy
  0-2-4-5-7

  Path melody → note-set → point-set

  • Drops order, duration, rests, repetition. A melody collapses to the unordered, untimed set of pitches it uses.
  • Drops root, register. A note set keeps its shape as offsets from its lowest note and forgets where it sits.

• Rhythmic pattern · Binary onsets

  lossy
  11111

  Path melody → rhythm → fractional-rhythmic-pattern

  • Drops pitch. A melody's timing alone — its durations and rests, with the pitches removed.

• Set class · Forte name

  lossy
  5-23B

  Path melody → note-set → pc-set → pc-set-analysis

  • Drops order, duration, rests, repetition. A melody collapses to the unordered, untimed set of pitches it uses.
  • Drops octave, register, duplication, order. A note set collapses to the unordered set of its pitch classes.
  • Drops transposition. The set's Tn class (Forte name with A/B, prime form); the transposition is dropped.
