01600		The B%4F%1 and F%4S%1 may be called either chromatic passing tones
01700	or tones which change the functions of the chords in question.  In the
01800	first instance our analysis would give:

04000		Neither of these results is completely satisfactory.  A mixture
04100	of the two might be given, because the 4th of a scale seems  a weaker
04200	tonic-determining factor than the leading tone, and the last
04300	chord of a phrase usually takes on more importance than the middle chords.
04400	Thus:

05500		One should not be overly concerned with such details unless
05600	the music indicates that the composer was intent on directing the
05700	listener's attention to them.  In most cases the actual duration of
05800	an alteration and its position in the phrase might be good bases
05900	for decisions.  For example, if the proper scale degree were involved,
06000	an altered note which was twice as long as its preceding unaltered
06100	form in the same chord  would tend to change the chord's function.
