In the spring of 1933, Samuel Barber (1910-1981) completed his formal
              studies at the Curtis Institute of Music in Philadelphia. It was a relief
              to him to leave there at last--he had studied at Curtis nine years. Luckily,
              at about this time, his Overture to The School for Scandal won the Joseph
              H. Bearns prize, $1500 which enabled him to live in Europe for a year.
              It proved to be the first of a series of awards that allowed him to remain
              in Europe for the next three years traveling and composing. In Italy in
              1936, he started a string quartet, and in September of that year he wrote
              to a friend, “I have just finished the slow movement of my quartet today--it
              is a knockout!” Indeed it was. In its arrangement for string orchestra,
              this movement would come to be performed the most often among Barber’s
              works and would be considered one of the sublime masterpieces of twentieth-century
              American music.
            Debussy: Danses Sacrée et Profane for Harp and String Orchestra (1904)
Claude
            Debussy (1862-1918), one of the great originals in the history of music,
            broke all the rules of harmony and counterpoint in order to develop a style
            at once beautiful, new and utterly French. The Danses, written in 1904,
            were the first pieces he completed after the premiere of his groundbreaking
            opera, Pelléas et Mélisande, in 1902. He wrote them in response to a commission
            from the Pleyel company, which was attempting to market the new Chromatic
            Harp. Since about 1810, the Pedal Harp had been the standard concert harp,
            as it is today. Its strings are tuned to the seven-note diatonic scale,
            and its pedals alter this tuning in order to obtain the other five pitches
            of the chromatic scale. In contrast, the Chromatic Harp had no pedals and
            was tuned solely to the chromatic scale. It embodied an experiment which
            involved a novel method of construction, a completely different playing
            technique and a very different sound. The experiment failed, however, as
            the chromatic harp was manufactured for a mere 30 years or so. As a matter
            of fact, Debussy detested it. Still, he wrote two major works for the instrument,
            the Danses Sacrée et Profane for Harp and String Orchestra and the Sonata
            for Flute, Viola and Harp, both of which are played on pedal harps today.
            The central idea of the Danses is the opposition of the Sacred and the
            Profane, considered from a purely aesthetic, “Debussyan” point of view.
            The moderately slow Danse Sacrée summons a sacred atmosphere through the
            use of Dorian and Lydian modal scales, as well as by the use of parallel
            fifths. The latter is reminiscent of organum, a musical technique developed
            in the tenth century for elaborating Gregorian Chant. The movement is laid
            out in three-part form, in which the prayerful opening section is repeated
            after a more urgent middle section. Though it sounds similar harmonically,
            the Danse Profane suggests the profane through a contrast in rhythm, gamboling
            along in waltz meter. It is arranged in a modified Rondo form with the
            main theme recurring frequently after short intervening excursions.
            
Stravinsky: Concerto in D for String Orchestra (1946)
Igor Stravinsky
            (1882-1971) is another of the great originals in the history of music,
            who developed an entirely new musical language. His, however, was a truly
            modern, twentieth-century language. Its harmony contains a high level of
            dissonance. Its phrase structure, the antithesis of nineteenth century
            German Romanticism and its flowing periods, is composed of short varied
            repetitions of idea-fragments. This modern style makes use of some of the
            harmonic practices of Stravinsky’s teacher Nikolai Rimsky-Korsakov and
            was inspired by the aesthetic creed of the “World of Art” movement in Russia,
            led by the impresario Sergei Diaghilev. The most famous of Stravinsky’s
            early “Russian” pieces which incorporates these influences is his Rite
            of Spring (1913), a piece which smashed to smithereens traditional notions
            of what had hitherto constituted “good music”. By 1946, a great deal had
            changed since he composed the Rite of Spring, both inside and outside of
            Igor Stravinsky. In 1940, he had come to the United States as a refugee
            from the war in Europe and declared his intention of becoming an American
            citizen. He had begun to write music dubbed “Neoclassical”, still recognizable
            as Stravinskyan in harmony and rhythm, but modeled on aspects of Mozart
            and Haydn. He had already written, among many other things, the Symphony
            in C and the Symphony in Three Movements. Now that he had accepted the
            commission for a work for strings from Paul Sacher of the Basel Chamber
            Orchestra, he was going to compose another work in a classical form, with
            a classical sense of balance and restraint. The title of this work, Concerto
            in D, conceals an important fact about it. “In D” usually means “in D major”.
            Here, it means only “in D”; that is to say, D is the tonic note, but it
            may be combined with F-sharp or F-natural or both, making D major, D minor,
            or--both at once. D can also be D-flat, the key of the Second Theme of
            the First Movement. D can even be a combination of C-sharp and D, the very
            dissonant interval of a minor ninth which begins the final movement. All
            of these various interpretations of “D”, this play with intervals, is not
            only arch-Stravinsky, but also represents a kind of loving parody of Stravinsky’s
            classical models: all is balanced, orderly, calm, restrained and graceful,
            but the language is modern. The first movement, marked Vivace, begins with
            a brief introduction in which the F-natural and F-sharp mentioned above
            are combined to form a dissonance. Then, in the main theme, they follow
            one another in a sort of teasing motive above a motoric accompaniment.
            The fairly elaborate working-out of this opening material becomes more
            and more fragmented at the end of the first section and dissolves finally
            into silence, out of which arises the D-flat Second Theme, a kind of blandishing
            hymn with little rhythmic feints and harmonic sweetnesses in chords. This
            section follows an A-B-A form within the A-B-A of the movement as a whole.
            After the repeat of the D-flat theme, some athletic, strongly marked music
            leads us back to a repeat of the motoric first theme. The whole first section
            is then recalled, if not actually repeated, with the D-flat theme now sounding
            in abbreviated form in D-major (again the play on different forms of D).
            A brief coda recalls the introduction and ends on a seventh chord in the
            basses and cellos. After the second movement, Arioso, a piece of gentle
            lyricism with a touch of irony, the third movement Allegro enters without
            a break. The form is laid out in an A-B-A-C-A pattern, whose A-idea is
            a rhythmically driven game of half-step clashes and fragmented chromatic
            scales. (Jerome Robbins, who choreographed this music in 1951, found it
            evocative of the life of bees.) After the two-part melodic B-section, the
            main idea is recalled, followed by a duet for violins (the C-section).
            The final statement of the bee-music concludes in rousing chords.
            
Elgar: Serenade in e for Strings (1892) Edward Elgar (1857-1934)
is
            considered to be the greatest English composer since Henry Purcell (1659-95).
            His music, particularly in his larger orchestral and choral works, is known
            for a uniquely Victorian English character that one cannot fail to recognize,
            even if unacquainted with what Englishness in music might be. His best
            known orchestral works are the Enigma Variations, two symphonies, the overture
            Cockaigne and the “symphonic study” Falstaff. Elgar grew up in Worcester,
            where his father, William, ran a music shop and where Edward was something
            of a wunderkind violinist and composer. His youthful accomplishments and
            undeniable talent helped form in him the high ambition to be a composer,
            an ambition frustrated in young adulthood by his financial circumstances.
            He was forced to fall back repeatedly on private teaching and playing in
            local orchestras in Worcester. These frustrations preyed upon his somewhat
            depressive turn of mind, and Elgar sometimes despaired of bringing to fruition
            the talent he knew was in him. Then, in 1892, two things happened to cheer
            him up and advance his career. First, he was commissioned by the Three
            Choirs Festival at Worcester to write an overture, a commission he fulfilled
            by composing Froissart, named for the great 14th century French chronicler.
            Froissart was well received by critics and audience alike and, what cheered
            Elgar even more, it was published by the English firm Novello. Later that
            year, he was roused from the doldrums again by an invitation to go to Bayreuth,
            Germany, to attend the great festival of Wagnerian opera. But it was not
            the music of Wagner which influenced the composition he began at this time,
            but rather some Sketches for string orchestra that Elgar himself had written
            several years previously. He succeeded at reworking them into some of the
            most beautiful and finely crafted music he had written up to that time.
            The first movement of the Serenade for String Orchestra contains two signal
            ideas. The first is the lilting staccato figure of repeated E’s in the
            violas at the beginning of the piece. The second idea is the melody of
            the middle portion of this three-part movement, which sweeps upward with
            the leap of a seventh and wends its way down again, lingering here and
            there on nodes of the E-major scale. Largetto, the second movement, opens
            with a kind of halting lyricism that yields to a flowing song. Finally,
            the third movement, while recalling the rhythm of the first, strikes a
            note of tenderness and delicacy, and in the coda, finds repose in returning
            to music heard when the piece began.
            
Mozart: Eine Kleine Nachtmusik (1787)
Eine Kleine Nachtmusik, one
            of Mozart’s most popular works, is probably the most famous serenade ever
            written. This genre was extremely popular throughout the eighteenth century
            and huge numbers of them were produced. The serenade was originally a song
            accompanied by guitar, offered by a lover to his beloved, typically under
            her window. In Salzburg, where Mozart was born and spent much of his life,
            the serenade took on a special form. It was used as an instrumental tribute
            to a person of importance on a signal day, such as graduation, homecoming,
            leave-taking or wedding. It opened with a march, during which the instrumentalists
            would process to the home of the honoree at about 9 in the evening. The
            ensemble processed in reverse direction during another march at the end
            of the piece. In between were played a series of dances alternating with
            slower lyrical movements. The latter were typically accompanied by strings
            played pizzicato--that is, with the strings being plucked--simulating the
            guitar, the original serenade instrument. The forms of the various movements
            were relatively loosely constructed and their emotional content was lighthearted
            and suggestive of idyllic pastoral scenes and moods. Most serenades were
            orchestral compositions written for a mixture of winds and strings. Ironically,
            Eine Kleine Nachtmusik, which literally means “A Little Serenade”, has
            no strumming pizzicato and no marches. It might better be called “A Little
            Symphony for Strings”. Indeed, it has as much in common with serenades
            of the nineteenth century as it does with those of its own time. The serenades
            of Dvorak, Tchaikovsky, Suk and Elgar, all of which were written after
            1850, while they share the idyllic pastoral associations of their eighteenth
            century ancestors, are more passionate than celebratory and are scored
            for strings or winds alone. Although our appreciation is aided by an understanding
            of the historical context in which a piece is written, it must be said
            that the enduring fame and popularity of Eine Kleine Nachtmusik clearly
            transcends any question of genre or influence. It remains a gem of Classical
            grace and balance, an fine example of the art which Mozart brought to every
            form he touched.
