A musical motive is a short musical idea that is consist of just a few notes or maybe a part of a larger theme. Shortening a musical motive is taking away some notes or only using a part of it
To shorten the musical motive, the composer uses fragmentation.
One of the most basic components of music motive development is fragmentation where one part of a motive may be repeated and then variations are introduced into it to distinguish it from the rest of the motive. This technique shortens the length of the motive.
