Composer note:
De Rerum Natura (2013) is a 25-minute orchestral tone poem commissioned by the University of Texas at Dallas for the opening of the Edith O'Donnell Arts and Technology Building. In keeping with the themes of Art and Technology, I have based the music on De Rerum Natura (On the Nature of Things) by the Roman poet Lucretius (first century B.C.). The Latin poem is a sweeping treatise on both science and the arts. In The Swerve, Stephen Greenblatt calls De Rerum Natura "a strikingly modern understanding of the world...a vision of atoms randomly moving in an infinite universe — imbued with a poet's sense of wonder. Wonder did not depend on the dream of an afterlife; in Lucretius it welled up out of a recognition that we are made of the same matter as the stars and the oceans and all things else. And this recognition was the basis for the way he thought we should live — not in fear of the gods, but in pursuit of pleasure..."

In my De Rerum Natura, I have followed the model of Leonard Bernstein's 1954 Serenade for violin and orchestra, based on the Symposium of Plato. Like Bernstein, instead of making a vocal setting of the text, I have created instrumental music that expresses ideas in the text. Since Lucretius' poem is in six "books," there are six movements, played without pause. Each movement has a subtitle taken from the poem. I have included incidental solos for violin and cello: the cello representing Lucretius and the violin representing Lucretius' hero, Epicurus, the Greek philosopher of the third century B.C. who taught that pleasure and pain are the only valid measures of good and evil.

I. Invocation of Venus ("...the place of fierce desire"). Lucretius begins De Rerum Natura with a sensuous hymn of praise to the Goddess of Love and to the joys of sexual experience. Botticelli's celebrated painting The Birth of Venus was inspired by this passage. The music opens with a passionate "desire" motive and builds to an ecstatic climax, followed by floating lines from the solo violin and cello.

II. Ricercare ("...where the mind soars at liberty") expresses Lucretius' secular humanist celebration of the intellect. As Greenblatt puts it, for Lucretius, "There is no master plan, no divine architect, no intelligent design. Nature restlessly experiments, and we are simply one among the innumerable results..." Here, the cello solo introduces a musical version of scientific inquiry. A traditional Lydian scale of seven pitches is established. Suddenly, an eighth pitch arrives from outside the system. The new pitch is pondered and then assimilated to create a new scale. Increasingly more complex harmony and counterpoint follow as the sequence moves through new pitches and keys. The "desire" motif from the previous movement drives the exploration forward until the complete spectrum of all twelve pitches is united in a powerful four-fold "Eureka!" outburst.

III. Variations: Skolion of Seikilos ("...loosening our bonds") deals with one of Lucretius' central themes: conquering the fear of death by rejecting the idea of eternal rewards or damnation and embracing, instead, a peaceful return to the elements from which we came. As Greenblatt writes, "When we look up at the night sky and marvel at the numberless stars, we are not seeing the handiwork of the gods or a crystalline sphere. We are seeing the same material world of which we are a part and from whose elements we are made... That is all; but it is enough." To represent death, I chose the earliest known example of Western music, a Greek song from 200 B.C. in Mixolydian mode written on a tombstone with the philosophical text, "Shine as long as you live. Do not grieve. Life is short. Time demands its end." The theme is stated in canon, with a tolling bell, followed by variations. The variations are pensive at first, then increasingly violent, depicting the terrors of death. The music reaches a tense climax and then drifts into a quiet coda marked by distant chimes.

IV. Scherzo ("...atoms that touch the senses with pleasure"). Lucretius takes delight in extolling each of the five human senses. Rather than depicting the senses one at a time, I use pizzicato strings with harp, piano and percussion accents to induce a general sensory tickling. The music bounces between a jig (in 12/8 time) and a slip-jig (in 9/8 time), with a roller-coaster fluctuation of dynamics between soft and loud. There is a woodwind interlude, as in the famous scherzo pizzicato from Tchaikovsky's Fourth Symphony, but instead of stopping, the strings continue in tremolo pizzicato, accompanying the winds as they play in lyrical pairs. When the winds have finished, the strings go on with their jig.

V. Fanfare & Cadenza ("...the swerve"). Lucretius believed in the importance of chance in the process of creation. Greenblatt says, "The stuff of the universe, Lucretius proposed, is an infinite number of atoms moving randomly through space, like dust motes in a sunbeam, colliding, hooking together, forming complex structures, breaking apart again, in a ceaseless process of creation and destruction." In this movement, there are three unexpected events (or "swerves," as Lucretius calls them): First, a brass fanfare bursts in to interrupt the Scherzo. A pounding C-sharp pedal point begins in the trombones and timpani and rises in the strings, culminating in wild horn and trumpet rips. In a second "swerve," the intensity suddenly cools, the repeated note switches to a quiet E-flat in the harp, the strings float upward, and gentler woodwinds take the place of the brass. In a final "swerve," the solo cello breaks into a cadenza, joined by the violin, with virtuoso variations on the previous Scherzo.

VI. Finale ("...heralds of godlike beauty") expresses Lucretius' joy in the arts as the perfect embodiment of his philosophy of reason, beauty and pleasure. The movement opens with a glowing reminiscence of the opening Invocation of Venus. Gradually, the music becomes more rhythmic, in keeping with Lucretius' characterization of the universe as "speeding... in endless dance," and a driving samba emerges. As the samba builds, led by the "desire" motif, the Ricercare, the jig, the Skolion (now triumphant) and other themes from the work whirl around merrily together to create, in honor of Lucretius, literally, a "Latin celebration."

…terrific work from composer Robert Xavier Rodríguez…a most attractive piece…De Rerum Natura (Of Things of Nature) is based on an extensive poem by Lucretius, who wrote in the first century BC. In six untitled books, the poet strives to nothing less than the explanation of how the entire universe works. He also opined that nature happens without a divine intervention…Rodríguez writes in a neo-romantic musical language, with neo and romantic offered in equal portions. He frequently uses instruments in the very top of their range, such as the solo violin and cello duet in the first movement…The scherzo was the most attractive movement from a compositional point of view. The outer fast sections scampered, and the middle contrasting section used the solo winds, one at a time, in a cadenza-like manner. The finale was suitably exciting, and even offered some "big-band" sounds in the brass.

His orchestration is also highly developed in this work. The texture goes from a single instrument to very thick passages with all of the instruments in the orchestra playing in a narrow pitch range or widely spread. His use of percussion is spare, using the battery more as seasoning. He makes a frequent use of repeated patterns (ostinato) over which he adds a series of layers. He also uses canonic writing, often at the unison. Frequently the sections of the orchestra trade what they are doing. Additionally, this work uses a solo violin and cello to great effect and adding the harp to the combination was lovely…a perfect 10.

Titled De Rerum Natura (Of Things of Nature), it was inspired by the first-century B.C. Latin poet Lucretius’ long philosophical poem of the same title. The six movements, played without pause, allude to the six "books" of the poem.

"Invocation of Venus" opens with dreamy, liquescent, scintillating music that grows in intensity. Overlapping brass fanfares and dialogues between solo violin and cello become recurrent gestures as the work proceeds. The second-movement Ricercare explores a seven-note motif; textures grow more complex as more pitches are added.

Tolling chimes announce variations on a Greek funerary song from 200 B.C., with increasingly militant music depicting terrors of death. A dancing scherzo evokes Lucretius’ "atoms that touch the senses with pleasure."

"Fanfare & Cadenza" is just that: more militant music, then a cello cadenza eventually joined by violin. The finale wraps themes from the earlier movements into a samba rhythm…this is appealing music, almost cinematic, smartly orchestrated.
