Chords of different tone quality used alternately.
1. The most usual practice is to employ chords on different groups of instruments alternately. In dealing with chords in different registers care should be taken that the progression of parts, though broken in passing from one group to another, remains as regular as if there were no leap from octave to octave; this applies specially to chromatic passages in order to avoid false relation.
Examples:
[No. 239.] Ivan the Terrible, Act II 29.
[No. 240]-[241]. The Tsar's Bride 123, before 124.
* [No. 242]-[243]. """ 178, 179.
* Note. The rules regulating progression of parts may sometimes be ignored, when extreme contrast of timbre between two adjacent chords is intended.
