Rachel Hippert (Soprano)
and Julián De La Chica (Piano & Synth)


Experimentelle und unbestimmte Lieder Op. 9 (Experiential and Indeterminate Songs, Op. 9) is a Cycle for soprano, piano and synthesizer composed by Julián De La Chica. The music narrates a spiritual experience through the five pillars of internal transit that the composer suggests are the fundamental basis of meditation.

Rachel Hippert is charged with personifying the wanderer that in her dark night and her silence, confronts her fears, her lies, her truths, and her ego. Subtly, Ms. Hippert confronts the void of nothing, of the unnecessary, to become the protagonist that risks everything.

Approx 75’

The Cycle Op. 9 is a work constructed with few elements, an austere and diaphanous work that leaves freedom to the listener, the surprising relationship between the flow of our listening and interior life. The piano invites the listener to prepare ourselves for meditation. A sound that seems to disappear with time introduces the voice that invokes darkness as an essential part of the process.  We submerge ourselves in a journey of introspection exploring the five fundamental pillars that De La Chica proposes as a guide for discernment and meditation: self-knowledge, acceptance, evolution, coherence, and illumination.

Concert notes

“Minimalism means concentration” - Anton Batagov (2016)
“Remove, remove and remove until only the essential is left.” – Eduardo Chillida

How does Julián De La Chica materialize the question of “being” in sound? Through text and music as sound material: the choice of the German tongue as a philosophic language; in its sonority, the reference to the tradition of Lieder, a form where word and sound construct a system of meanings in search of the essential. Materializing it through sound, the works achieve this “concentration” of the essential, guided by the question of the “being.”

But, how do they achieve it? Long phrases, almost Gregorian rhythmicity, recuperate the capacity for enunciation born of medieval liturgical chant and Buddhist mantras. The concentration of power in the invoked words – to enunciate is to make real what is invoked. The essence is enunciated in the concept, in the construction of the enunciations that constitute the exoskeleton of these songs. The sound materializes the concept; it is sound that creates reality. The sound is in the center of the congealed hurricane. A person that asks the question of “being”, stops time. Their presence is now; only the now exists. That instant is nonetheless a whirlwind that in the meditative act stops in front of the asking person and contemplates their mortal state, unappealable: the state of mortality as illumination.  

Piano and synthesizer induce vision. The compositional technique of the author is almost sculptural, tuning in with Eduardo Chillida: “Remove, remove and remove until only the essential is left.” In this way, it achieves what Anton Batagov (2016) summarizes in a sentence: “Minimalism means concentration.”

Rachel Hippert weaves an ontological experience with her voice. The soprano understands the underlying magma underneath the Gregorian tradition, mantra, and Lieder at the conceptual level. Her work is rigorous, contained and subtle. The dissonance between her voice and the sculptural piano and synthesizer can materialize flashes of something seen for only a moment.

The voice is a hologram of the sonic imagination, of the intellectual process of Rachel Hippert. “The quiet and still persists," Mr. Chillida wrote. In times like ours, where speed and media urgency seem to demarcate thought and creation, she stops, and with her voice, shows the density of space. Ms. Hippert seems to explore the quality that Mr. Chillida imagined in his sculptures: “I want my works to be still and quiet, the only way of escaping in part the influence of time.”
