	These diagrams may appear somewhat unwieldy, but they have
the advantage of giving clear pictures, in intervallic terms, of the
relationships involved.
 

	Occasionally a very rapid movement through part of the circle
of fifths, or the successive use of 7th chords, will cause certain
elements of a progression to stand in relief.

	In the above diagram, the abrupt skip down to a third
level of tonics (which resolves to a I on the second level)
accurately parallels the effect of the example.  Notice the problems 
created by the use of a string of diminished chords over a basically
chromatic line.  Such situations may be analyzed as
substitutes for the "circle of fifths" progression, but generally it
is best to consider all but the first and last chords of the string
as parallel-moving passing chords (see Bach, %2Partita #1 in B%4F%1, Gigue;
Mozart, %2Fantasy in C%1, K.394).  However, in 19th-century music,
details of voice leading (especially the melodic skips) often tend
to give functional importance to the inner chords of strings of
