Here, for example, I see the following rule:
Consecutive leaps should outline a triad
What does it exactly mean?
My assumption was that, if we have a sequence of tones that leaps-wise go in one direction, then the first note of the sequence and the last note of the sequence should span a chord (triad). In other word, the interval between the first and the last note of the sequence should be 5th (interval between the first and last note of a chord consisting of 3 tones).
However, it is clear that my interpretation does not make sense, since my restriction can be fulfilled only by two leaps of 3d interval (3d + 3d = 5th).
