/------------------/

variation --- decoration

|- simplification

\- modification

expansion --- vertical

\- horizontal

sequence --- rising sequence (repeat at higher pitch)

|- falling sequence (repeat at lower pitch)

\- diatonic remains in same key

inversion

diminution -- repartition in shorter note values

augmentation- repartition in longer note values

ostinarto --- short group of notes repeated over

and over with small variations







Motif short recognisable

Figure short for forming repeated pattern

theme longer recognisable + recurrent

may or may not sound complete

Melody longer sounds complete in itself

or tune
