Definition
Fortspinnung (spinning-forth in English) is a german term conceived in 1915 to refer a specific process of development of a musical motif. In this process, the motif is developed into an entire musical structure by using sequences, intervallic changes or simple repetitions.

It is also possible to use the fortspinnung form term that stands for a structure with three parts:
 * The antecedent or exposition of the motif.
 * The fortspinnung itself where the motif is developed.
 * The epilogue or cadence section.

Examples
The use of this process of development and musical structure is focused mainly in the Baroque period. Here we can see an example of the fortspinnung process in the first section of the Johann Sebastian Bach Invention No.4 in D minor (BWV 775) :



Even though it is a Baroque technique, it is also possible to find this process in scores from other composers in different periods, such as Johannes Brahms in the Romantic period:
