• left hand + right hand together, one voice each:

    • octaves - basic, not trivial
    • skip a note between voices, so alternate P5, m6, M6
    • skip three notes between voices, so alternate M10, m10, P11

  • 8 note voicings (the Rachmaninoff voicings in the B section of Prelude in G minor)

    • simply all three 3 inversions of 8 notes in a row (4 in each hand)

  • suspensions/enclosures

    • structure
      • one hand plays two chord tones, skipping a voice between them
      • other hand plays the other voice directly above (or below), but starts on the half step above and “encloses” that chord tone
      • e.g., one hand: C + G, other hand: F-E-Eb-E
    • possibilities (at least the most basic ones)
      • 3 possible enclosures starting half step above
        • ♭9-1 - reminds of “indignation” and some very classical composers, specifically, I think of Mozart, Beethoven, Schubert, even Bach
          • first sounding is composed of 2 stacked minor 6ths (i.e., 5 3 ♭9 ascending)
        • 4-3 - restful, but slightly dissonant starting on that 4
        • ♭6-5 - shares the very classical sound with the ♭9-1
          • first sounding is composed of 2 stacked major 6ths (i.e., 3 1 ♭6 ascending)
      • 3 possible enclosures starting whole step above
        • 9-1 - perhaps the most at rest of all 6
        • ♯11-3 - very unsettled obviously
        • 6-5 - playful, basic
    • observations
      • when upper voice plays the enclosure, both of the ones that start with stacked 6th have the most balanced sound, powerful in the 2 octaves below middle C, in particular.
      • intervals change when lower voice plays the enclosure; leads to very different sound
