Repetition of a basic idea

The info on this page is either entirely based on or mostly based on the content published in caplin-2013 or caplin-1998. Caplin is considered to be responsible for reviving interest in the analysis of form in North American music theory.

While Caplin’s impact cannot be understated, it is worth understanding that his 1998 work (and his 2013 followup) are focused on Classical music: particularly the works of Haydn, Beethoven, and Mozart. It is important to not assume other styles of music (both preceding and following the classical era, or music in other parts of the world) follow these same conventions. Music theory is descriptive, not prescriptive, and so the theory you see describing what was common in the Classical era may not apply to anything else.

In a sentence, there are 3 techniques to repeat a basic idea.

In each case, the melody is either repeated verbatim (transposed or not) or repeated with some embellishments.

#🎼 Examples of each.

Exact repetition

The harmony of the basic idea is repeated verbatim.

Statement-response repetition

The harmony is changed to a different harmony, almost always the dominant, rarely the predominant.

In this technique, the melody will be modified (not necessarily transposed) to fit the new harmony. It will follow the same contour and rhythm but the intervals may be different.

Here are the most common cases:

Basic Idea	Repetition
$I$ | $I$	$V$ | $V$
$I$ | $V$	$V$ | $I$
$I$ | $II$	$V$ | $I$
$I$ | $IV$	$V$ | $I$
$I$ | $I$	$IV$ | $IV$

Sequential repetition

The harmony changes to a different harmony, and the melody is transposed to fit the new harmony. Thus, it is a sequence.

Typically it will be one of these:

Basic Idea	Repetition
$I$ | $I$	$II$ | $II$
$I$ | $I$	$VI$ | $VI$
