Problem: Background: An orchestra ( or US: ; Italian: [or'kestra]) is a large instrumental ensemble typical of classical music, which mixes instruments from different families, including bowed string instruments such as violin, viola, cello and double bass, as well as brass, woodwinds, and percussion instruments, each grouped in sections. Other instruments such as the piano and celesta may sometimes appear in a fifth keyboard section or may stand alone, as may the concert harp and, for performances of some modern compositions, electronic instruments. The term orchestra derives from the Greek orkhestra (orchestra), the name for the area in front of a stage in ancient Greek theatre reserved for the Greek chorus. A full-size orchestra may sometimes be called a symphony orchestra or philharmonic orchestra.
Context: Apart from the core orchestral complement, various other instruments are called for occasionally. These include the flugelhorn and cornet. Saxophones and classical guitars, for example, appear in some 19th- through 21st-century scores. While appearing only as featured solo instruments in some works, for example Maurice Ravel's orchestration of Modest Mussorgsky's Pictures at an Exhibition and Sergei Rachmaninoff's Symphonic Dances, the saxophone is included in other works, such as Ravel's Bolero, Sergei Prokofiev's Romeo and Juliet Suites 1 and 2, Vaughan Williams' Symphonies No.6 and 9 and William Walton's Belshazzar's Feast, and many other works as a member of the orchestral ensemble. The euphonium is featured in a few late Romantic and 20th-century works, usually playing parts marked "tenor tuba", including Gustav Holst's The Planets, and Richard Strauss's Ein Heldenleben. The Wagner tuba, a modified member of the horn family, appears in Richard Wagner's cycle Der Ring des Nibelungen and several other works by Strauss, Bela Bartok, and others; it has a prominent role in Anton Bruckner's Symphony No. 7 in E Major. Cornets appear in Pyotr Ilyich Tchaikovsky's ballet Swan Lake, Claude Debussy's La Mer, and several orchestral works by Hector Berlioz. Unless these instruments are played by members "doubling" on another instrument (for example, a trombone player changing to euphonium or a bassoon player switching to contrabassoon for a certain passage), orchestras typically hire freelance musicians to augment their regular ensemble.  The 20th-century orchestra was far more flexible than its predecessors. In Beethoven's and Felix Mendelssohn's time, the orchestra was composed of a fairly standard core of instruments, which was very rarely modified by composers. As time progressed, and as the Romantic period saw changes in accepted modification with composers such as Berlioz and Mahler; some composers used multiple harps and sound effect such as the wind machine. During the 20th century, the modern orchestra was generally standardized with the modern instrumentation listed below. Nevertheless, by the mid- to late 20th century, with the development of contemporary classical music, instrumentation could practically be hand-picked by the composer (e.g., to add electric instruments such as electric guitar, electronic instruments such as synthesizers, non-Western instruments, or other instruments not traditionally used in orchestra).  With this history in mind, the orchestra can be analyzed in five periods: the Baroque era, the Classical music period, early/mid-Romantic music era, late-Romantic/early 20th century music and 21st century era. The first is a Baroque orchestra (i.e., J.S. Bach, Handel, Vivaldi), which generally had a smaller number of performers, and in which one or more chord-playing instruments, the basso continuo group (e.g., harpsichord or pipe organ and assorted bass instruments to perform the bassline), played an important role; the second is a typical classical period orchestra (e.g., early Beethoven along with Mozart and Haydn), which used a smaller group of performers than a Romantic music orchestra and a fairly standardized instrumentation; the third is typical of an early/mid-Romantic era (e.g., Schubert, Berlioz, Schumann); the fourth is a late-Romantic/early 20th century orchestra (e.g., Wagner, Brahms, Mahler, Stravinsky), to the common complement of a 2010-era modern orchestra (e.g., Adams, Barber, Aaron Copland, Glass, Penderecki).

Problem: Background: Howard Duane Allman (November 20, 1946 - October 29, 1971) was an American guitarist, session musician, and co-founder and leader of the Allman Brothers Band until his death following a motorcycle crash in 1971, at the age of 24. The Allman Brothers Band was formed in Jacksonville, Florida, in 1969. The band had great success in the early 1970s. Allman is best remembered for his brief but influential tenure in the band and in particular for his expressive slide guitar playing and inventive improvisational skills.
Context: Duane Allman was born on November 20, 1946, in Nashville, Tennessee. He was the eldest son of Willis Allman (1918-1949), a World War II non-commissioned officer turned recruiting officer in the United States Army, and Geraldine Allman (nee Robbins) (1917-2015). His brother, Gregg, was born on December 8, 1947.  On December 26, 1949, when the family was living near Norfolk, Virginia, Willis Allman was murdered. In order to retrain as an accountant, Geraldine "Mama A" Allman sent Duane and Gregg to Castle Heights Military Academy in Lebanon, Tennessee, which they both disliked intensely. In 1957, the family moved to Daytona Beach, Florida, where the boys attended Seabreeze High School.  The boys returned to Nashville to spend summers with their grandmother, and there Gregg learned guitar basics from a neighbor. In 1960, he had saved enough money to buy his first guitar, a Japanese-made Teisco Silvertone, while Duane acquired a Harley 165 motorbike. Despite Duane being left-handed, he played the guitar right-handed. Duane began to take an interest in the guitar, and the boys would sometimes fight over it, until Duane wrecked the motorbike and traded it for a Silvertone of his own. His mother eventually bought Duane a Gibson Les Paul Junior.  It was also in Nashville that the boys became musically inspired by a rhythm and blues concert where they saw blues guitar legend B. B. King perform. Duane told Gregg, "We got to get into this." Duane learned to play very quickly and soon became the better guitarist of the two.
