55. When movement is suggested by any series of attitudes and the
movement is regulated by equal or regularly progressive intervals, we
have a Rhythm of Attitudes.
[Illustration: Fig. 57]
In this case the changes of attitude suggest a falling movement to
the right and down. In the regular progression of this movement
through marked intervals we have the effect of Rhythm, in spite of
the fact that the relation of positions repeated has axial balance.
The intervals in this case correspond, producing Interval-Harmony.
The force of this Rhythm might be increased if the relation of
positions repeated suggested a movement in the same direction. We
should have Rhythm, of course, in the repetition of any such unstable
attitude-rhythms at equal or lawfully varying intervals.
