Sebastian Ars Acoustica's video: Anton Webern: Konzert f r neun Instrumente op 24 - I Etwas lebhaft 1934

Anton Webern's Concerto for Nine Instruments, Op. 24 (German, Konzert für neun Instrumente, op. 24, 1934) is a twelve-tone concerto for nine instruments: flute, oboe, clarinet, horn, trumpet, trombone, violin, viola, and piano; containing three movements: I. Etwas lebhaft, II. Sehr langsam, and III. Sehr rasch; and composed with a derived row, often cited [such as by Milton Babbitt (1972)] as a paragon of symmetrical construction. In the words of Luigi Dallapiccola: a work of incredible conciseness . . . and of unique concentration . . . . Although I did not understand the work completely, I had the feeling of finding an aesthetic and stylistic unity as great as I could wish for. [Prague, September 5, 1935]. The second movement limits quite severely the values of many domains, for example featuring only two durational values (quarter and half note[s]), and, partly as a result, features great uniformity in texture and gesture. The opening displays [the Concerto's] distinctive trichordal structuring, four of which comprise an aggregate, or partition. The six combinations of [the partition's] trichords generate three pairs of complementary hexachords. Webern takes full advantage of this property [its fourfold degree of symmetry] in the Concerto, that under four appropriate transformations (T0T6I5IB), the tone row maintains its unordered trichords (j=019,091,etc., k=2te, l=367, and m=458). The hexachord featured is sometimes called the 'Ode-to-Napoleon' hexachord (014589). Video created with Sonic Visualizer, vokoscreen and OpenShot on a Debian 8 Jessie Linux System.
