Webster 1828 Edition

ppr.

Leaping; bounding. Skipping notes, in music, are notes that are not in regular course, but separate.

skipping

skipping ‎(plural skippings)

The act by which something is skipped or omitted.
- 2008, Manfred Schroeder, Number Theory in Science and Communication (page 143)
  Suppose we permit irregular skippings and connect, for example, 1 with 3 with 6 with 2 with 4 – but now we cannot skip any more because the only missing point is the adjacent point 5.
