Melodic Transformation

Involving a transformation in:

==> Nothing: Repetition

 

==> mode

• major to minor
• minor to major
• .....................

 

==> The number of pitches

• Deletion of pitches
  • same length: Thinning
  • shorter
  • longer
• Addition of pitches: Ornamentation

   

==> Direction

• Mirror image: Inversion
  • exact mirror image
  • overall contour mirror image
• Backward: Retrograde

 

==> Intervals

• Larger intervals: Intervalic Augmentation (Expansion)
• Smaller intervals: Intervalic Diminution (Contraction)

 

==> Duration

• Longer Duration: Rhythmic Augmentation
• Shorter Duration: Rhythmic Diminution

 

==> Size

• Smaller (a segment of the whole): Fragmentation
  • deleting notes
  • replacing notes with rests
• Larger (lengthening the motive):
  • In the middle: Expansion (Interpolation)
  • At the end: Extension
• Same size, but fragments repeated in a different order: Interversion

 

==> Starting point

In the same key?

• Yes: Sequence
• Special Case - same tones, higher/lower octaves: Change of Register
• No: Transposition
