The idea of an umbra came naturally while imagining a double concerto for cello and Ondes Martenot with a string orchestra. The immediate impression of the cello and Ondes Martenot side by side was that they were wildly different not only in appearance and the nature of sound production, not to mention how long they have existed in Western music history. However, it grew over time that there were many aspects conceptually that are quite similar in the production of sound, such as vibrato and glissando – the performance practices that transmit and express emotions deeply and effectively to humans. Also, both instruments require no mandatory breathing breaks and offer virtually endless options of timbral variations, which became significant assets brought into the compositional palette.

Originating from celestial mechanics – the motions of objects like planets, moons, and stars under the influence of gravitational forces – Umbra can be described as a continuous cycle of alternating March and Dance.

The pivotal component of Umbra is the layering of simple but independent rhythmic cycles, like the cycle of an eclipse that results in the umbra. While built on consonances and soft dissonances extracted from the overtone series, this layering of simple independent rhythmic cycles collectively results in auditorily satisfying just the perfect dose of complexity.

Umbra is structured in a nested ternary form embracing a large-scale rondo. The most recognizable macro level of contrasting alternation of Marches and Dances is the Non-Sequitur March and Dance, placed in the center of the composition, which takes a timbral excursion of somewhat unexpected and inscrutable character – a musical diversion analogous to imagining a lost time traveler in the middle of a pitch-dark atmosphere with twinkling distant stars.

Although titled after the phenomenon of umbra, the darkest and most dissonant section lasts for only 3 minutes overall within the 23-minute-long musical journey. The spirit of Umbra is bright and uplifting in robust changes and quick shifts of musical ideas in developed reprises, reflecting how humans may experience the perpetual changes in the cycle.

Adopting the practice of the traditional concerto, where the roles of soloists and the support of the orchestra are defined, the intricate interplay between the two soloists unfolds at a melodic level, often tracing, catching up, and accompanying each other, while the relationship between the soloists and the orchestra goes as far as all intertwined as an ensemble, blurring the boundary between the soloists and the accompaniment.

Musical tensions are frequently generated by alternating blocks of modern-sounding and traditional-sounding music, by pitting against the continuity and changes, and constant renewal of never-ending variations, including even the functions of the three players (cello, Ondes Martenot, and string orchestra) with the agility yielded by the superimposition of layers.

This dynamic interplay contributes to a rich auditory experience, reflecting on the underlying themes of light and shadow. Importantly the musical concept emphasizes the consistently progressive nature of the universe that leads to eternity where no ultimate destination can be defined.
