Translated as "Sway of The Cradle", this striking piece is punctuated with a surprising sorrow unexpected from a lullaby. Its tender melody calls to mind the calm of childhood sleep, with a soothing rhythm that mimics the lull of a rocking cradle. However, these serene aspects belie the yearning that is evident throughout the work. The text first presents an adult persona nostalgic of his innocent past. The emotion eventually melds into his longing for the comfort found only in his mother's arms. Such a longing is reminiscent in Brahms' Heimweh II or 'Homesickness II' (with text by Klaus Groth).
Ugoy Ng Duyan, which he composed while on his way home to Philippines aboard a ship with master lyricist Levi Celerio (who penned the words after Maestro San Pedro set down the melody). "Sa Ugoy Ng Duyan," now a classic Filipino lullaby, also forms the fourth movement of his most famous orchestral work, "Suite Pastorale," which pays tribute to his hometown to Angono.
