Andante

In the expository first movement, Andante (Continuous), there are two groups each of four variations that explore harmonies associated with the ostinato. The first group – Oscuramento (Darkening), Misterioso (Mysterious), Irrequieto (Restless) and Giocoso (Jocose) – presents the ostinato alone and then punctuated by a series of harmonies derived from the ostinato. The second group uses triadic harmony and increasing fracturing of the ostinato among different parts to support an intensifying of affect – Tranquillo (Calm), Marcato (Marked), Ritmico (Rhythmic) and Esultante (Jubilant).
