11. The leap of a third (called a narrow leap), used in the first les-
son, is always good. But all wider leaps are generally hazardous, and
require specific limitations. The principal consideration is as follows :

Rule 3. Any wide skip is natural, and permissible, when both tones
belong to the same good chord.
12. The "good " chords are the primary triads on scale-steps I, V,
IV ; also the II, though more rare ; also the chords of the Dominant-7th
and Dominant-gth. The chords on steps VI and III, and all subordi-
nate dissonant chords, are too inferior to afford justification for wide
leaps. Thus, in C major :



Good Chords.
Rare. Inferior.

The following are unnatural, in either direction, and must be avoided,

14. Rule 4. Two or more leaps in the same direction, whether nar-
row or wide, are also strictly subject to this rule : All the tones must be-
long to the same good chord. Thus, C major :

Note. In the first group, the first skip (c to g) represents the I, but the next
tone, reached with a leap in the same direction, does not belong to that (same) chord.
