Arvo Pärt (] ; born 11 September 1935) is an Estonian composer of classical and religious music.
 Since the late 1970s, Pärt has worked in a minimalist style that employs his self-invented compositional technique, tintinnabuli.
 Pärt's music is in part inspired by Gregorian chant.
 His most performed works include "Fratres" (1977), "Spiegel im Spiegel" (1978), and "Für Alina" (1976).
 Pärt has been the most performed living composer in the world for five consecutive years.
Stabat Mater is a musical setting of the Stabat Mater sequence composed by Arvo Pärt in 1985, a commission of the Alban Berg Foundation.
 The piece is scored for a trio of singers: soprano, alto, and tenor; and a trio of string instruments violin, viola, and violoncello; it has a duration of approximately 24 minutes.
 A version with expanded forces (mixed chorus and orchestra) was premiered on June 12, 2008 at the Großen Musikvereinssaal during the Wiener Festwochen 2008 with Kristjan Järvi conducting the Singverein der Gesellschaft der Musikfreunde in Wien and the Tonkünstler-Orchester Niederösterreich.
 This new version was commissioned by the Tonkünstler-Orchester.
 "Stabat Mater" is composed in Pärt's characteristic tintinnabuli style (which he has employed nearly exclusively since 1976) in which arpeggiations of a major or minor triad are combined with ascending or descending diatonic scales.
Wozzeck (] ) is the first opera by the Austrian composer Alban Berg.
 It was composed between 1914 and 1922 and first performed in 1925.
 The opera is based on the drama "Woyzeck", which was left incomplete by the German playwright Georg Büchner at his death.
 Berg attended the first production in Vienna of Büchner's play on 5 May 1914, and knew at once that he wanted to base an opera on it.
 From the fragments of unordered scenes left by Büchner, Berg selected fifteen to form a compact structure of three acts with five scenes each.
 He adapted the libretto himself, retaining "the essential character of the play, with its many short scenes, its abrupt and sometimes brutal language, and its stark, if haunted, realism..."
"Schliesse mir die Augen beide" is a poem by Theodor Storm, twice set to music by Alban Berg.
 Berg composed his first setting in 1907, dedicating it to his future wife.
 The second version was composed in 1925 to celebrate the 25th anniversary of the Universal Edition music publisher.
 This second setting was Berg's first full-fledged 12 tone composition, and he re-used its tone row, or rather its secondary set, in the first movement of the "Lyric Suite" for string quartet of 1926.
Alban Berg's Violin Concerto was written in 1935 (the score is dated 11 August 1935).
 It is probably Berg's best-known and most frequently performed instrumental piece, in which the composer sought to reconcile diatonicism and dodecaphony.
 Berg composed it on a commission from Louis Krasner, and it became the last work that he completed.
 Krasner performed the solo part in the premiere at the Palau de la Música Catalana, Barcelona on 19 April 1936, after the composer's death.
The Five Orchestral Songs (German: "Fünf Orchesterlieder, nach Ansichtkarten-Texten von Peter Altenberg" ), Op.
 4, for medium voice and orchestra, were composed by Alban Berg in 1911/12.
 Numbers 2 and 3 were premiered under the baton of Berg's teacher Arnold Schoenberg at the Vienna Musikverein on 31 March 1913, known as the "Skandalkonzert" for the riot that erupted during Berg's songs.
 The texts are taken from picture-postcard texts ('Ansichtskartentexte' in German ) by the contemporary Viennese poet Peter Altenberg (hence the more commonly used title Altenberg Lieder ).
 The texts deal with the stormy but beautiful condition of the soul, and the palpable sensations of love and longing.
 Berg's setting is for a large orchestra.
 The music has many displaced ostinati and the conflicted, lyrical passion found in much of Berg's works.
The Alban Berg Quartett was a string quartet founded in Vienna, Austria in 1970, named after Alban Berg.
Walter Levin (December 6, 1924 – August 4, 2017) was the founder, first violinist, and guiding spirit of the LaSalle Quartet (active 1947–1987), which was known for its championing of contemporary composers, for its recordings of the Second Viennese School (Arnold Schoenberg, Alban Berg, and Anton Webern), as well as for its intellectually penetrating interpretations of the classical and romantic quartet repertory, in particular the late quartets of Beethoven.
 Levin was also an important pedagogue, having taught many of the world’s leading string quartets, among them the Alban Berg Quartet and the Arditti Quartet; other prominent students include the conductor James Levine, the violinist Christian Tetzlaff and the pianist Stefan Litwin.
The Joe Berg Science Seminars began providing enrichment to high school students in the 1950s.
 It began as a challenge to encourage science and engineering students at the high school level through science projects and science fair competitions in response to the launch of Sputnik by the Soviet Union.
 At one time, there were more than 700 Joe Berg science seminar programs throughout North America.
 Now only two are known to exist: the Wachusett Regional High School Science Seminar in Holden, MA, founded in 1959, and the Jacksonville Joe Berg Seminars in Jacksonville, Florida, founded in 1960.
 The Jacksonville Joe Berg Seminars is part of the University of North Florida's Science and Culture Initiative.
 The Jacksonville program includes a humanities track, started in 1963, along with the sciences track, whereas the Massachusetts program more closely follows the original Joe Berg Foundation concept.
Symphony No. 6 in A minor by Gustav Mahler is a symphony in four movements, composed in 1903 and 1904 (revised 1906; scoring repeatedly revised).
 Mahler conducted the work's first performance at the concert hall in Essen on May 27, 1906.
 It is sometimes referred to by the nickname "Tragische" ("Tragic").
 Mahler composed the symphony at what was apparently an exceptionally happy time in his life, as he had married Alma Schindler in 1902, and during the course of the work's composition his second daughter was born.
 This contrasts with the tragic, even nihilistic, ending of No. 6.
 Both Alban Berg and Anton Webern praised the work when they first heard it.
 Berg expressed his opinion of the stature of this symphony in a 1908 letter to Webern:
