Traditionally, a Jig (or Gigue) has been a lively dance with leaping movements, comprised of two sections each repeated. Somewhat of a cross between “Jazz” (Monk, Coltrain, Tatum, Miles, etc.) and “Classical” (Bartok, Brahms, Stravinsky, etc.) Moon Jig
can be heard as a series of outgrowths and variations, which are organic and, at every level, concerned with transformations and connections. The piano serves as the protagonist as well as fulcrum point on and around which all musical force-fields rotate, bloom and proliferate.
The piano part starts with (and returns four times with) a low register jig, which is an earthy, punchy, rhythmic, asymmetrical walking bass. The second, contrasting section (which is also repeated 4 times) is always led by the strings who play long animated, expressive lines.
This very short work alternates 5 times total between these two sections:
PIANO JIG – TUTTI – PIANO JIG – TUTTI – PIANO JIG, and so forth, yet as the repetitions proceed, the two musics eventually blend together. One clear-cut example is when the string pizzicatos blend into the low-register, jazzy piano rhythms. A multifaceted merging process finally results in one long sweep of music rushing to the end in the highest registers of the trio, as if the Jig leaped skyward and moonward.
