  • Pentatonality matrix: The octave of a regular pentatonality includes two Reach steps, three whole steps, and no half step (or semitone). One or two consecutive whole steps frame and separate the two Reach steps. A clustered pentatonality has two consecutive Reach steps and three consecutive whole steps. Some further basic pentatonalities contain three Reach steps, at least two of them consecutive. And extended pentatonalities include a double whole step plus one or two Reach steps.
  • PentaNaReach: The name indicates that this is a pentatonality consisting of the first primary Na(tural) harmonics or overtones along with the upper tetrachord containing a regular Reach step, i.e. containing the minor sixth and major seventh in addition to the initial pitches in the Na series.
  • Step pattern: Ascending from the fundamental (tonic or Do), an augmented Reach step spanning over four semitones leads to a regular Reach step. Then follows a half step and another Reach step. Finally a second half step leads up to the octave.
  • Scale intervals: Major third, quint, minor sixth, and major seventh.
  • Tetra- and trichords: The lower trichord is TetraNa and the upper tetrachord is harmonic or Reach.
  • Harmonic axes: There is no axis.
  • Primary harmonic anchors: The fundamental or North anchor is partially present with its head and right leg. The East and South or contrast anchor each only has its left leg, the West anchor only its right leg.
  • Secondary harmonic anchors: There is no secondary anchor.
  • Penta- to hepta- and hexatonality correlation: PentaNaReach is equivalent to HexaProReach without second or to ReachBal, ReachNaBal, MajReach, or LydReach / NaReach without second and quart or tritone. And it is closely related to PentaBluReach, PentaNaMin, and PentaNaMaj.
