Problem: Background: Kurt Julian Weill (March 2, 1900 - April 3, 1950) was a German composer, active from the 1920s in his native country, and in his later years in the United States. He was a leading composer for the stage who was best known for his fruitful collaborations with Bertolt Brecht. With Brecht, he developed productions such as his best-known work The Threepenny Opera, which included the ballad "Mack the Knife". Weill held the ideal of writing music that served a socially useful purpose.
Context: Back in Berlin, Weill had an interview with Ferruccio Busoni in December 1920. After examining some of Weill's compositions, Busoni accepted him as one of five master students in composition at the Preussische Akademie der Kunste in Berlin. From January 1921 to December 1923, Weill studied music composition with him and also counterpoint with Philipp Jarnach in Berlin. During his first year he composed his first symphony, Sinfonie in einem Satz, as well as the lieder Die Bekehrte (Goethe) and two Rilkelieder for voice and piano. To support his family in Leipzig, he also worked as a pianist in a Bierkeller tavern. In 1922, Weill joined the November Group's music faction. That year he composed a psalm, a divertimento for orchestra, and Sinfonia Sacra: Fantasia, Passacaglia, and Hymnus for Orchestra. On November 18, 1922, his children's pantomime Die Zaubernacht (The Magic Night) premiered at the Theater am Kurfurstendamm; it was the first public performance of any of Weill's works in the field of musical theatre. Out of financial need, Weill taught music theory and composition to private students from 1923 to 1925. Among his students were Claudio Arrau, Maurice Abravanel, Heinz Jolles (later known as Henry Jolles), and Nikos Skalkottas. Arrau, Abravenel, and Jolles remained members of Weill's circle of friends thereafter, and Jolles's sole surviving composition predating the rise of the Nazi regime in 1933 is a fragment of a work for four pianos he and Weill wrote jointly. Weill's compositions during his last year of studies included Quodlibet, an orchestral suite version of Die Zaubernacht, Frauentanz, seven medieval poems for soprano, flute, viola, clarinet, French horn, and bassoon, and Recordare for choir and children's choir to words from the Book of Lamentations. Further premieres that year included a performance of his Divertimento for Orchestra by the Berlin Philharmonic under the direction of Heinz Unger on April 10, 1923, and the Hindemith-Amar Quartet's rendering of Weill's String Quartet, Op. 8, on June 24, 1923. In December 1923, Weill finished his studies with Busoni.
Question: Who is Busoni?
Answer: Busoni accepted him as one of five master students in composition at the Preussische Akademie der Kunste in Berlin.

Background: Patsy Cline (born Virginia Patterson Hensley; September 8, 1932 - March 5, 1963) was an American country music singer and part of the Nashville sound during the late 1950s and early 1960s. She successfully "crossed over" to pop music and was one of the most influential, successful, and acclaimed vocalists of the 20th century. She died at age 30 in the crash of a private airplane. Cline was known for her rich tone, emotionally expressive and bold contralto voice, and her role as a country music pioneer.
Context: Bill Peer, her second manager, gave her the name Patsy, from her middle name, Patterson. (Bill Peer, who had a country music band in Brunswick, MD, also had an infant daughter named Patsy). In 1955 he gained a contract for her at Four Star Records, the label he was then affiliated with. Four Star was under contract to the Coral subsidiary of Decca Records. Patsy signed with Decca at her first opportunity three years later. Her first contract allowed her to record compositions only by Four Star writers, which Cline found limiting. Later, she expressed regret over signing with the label, but thinking that nobody else would have her, she took the deal. Her first record for Four Star was "A Church, A Courtroom & Then Good-Bye," which attracted little attention, although it led to appearances on the Grand Ole Opry. As these performances were not "records" per se, they were not governed by her contract, and she could sing what she wanted, within reason. This somewhat eased her "stifled" feeling. Between 1955 and 1957, Cline recorded honky tonk material, with songs like "Fingerprints," "Pick Me Up On Your Way Down," "Don't Ever Leave Me Again," and "A Stranger In My Arms." Cline co-wrote the last two. None of these songs gained notable success. She experimented with rockabilly. According to Decca Records producer Owen Bradley, the Four Star compositions only hinted at Patsy's potential. Bradley thought that her voice was best-suited for pop music, but Cline sided with Peer and the other Four Star producers, insisting that she could only record country songs, as her contract also stated. Every time Bradley tried to get her to sing the torch songs that would become her signature, she would panic, missing her familiar country fiddle and steel guitar. She often rebelled, only wishing to sing country and yodel. She recorded 51 songs with Four Star.
Question: Did she leave?
Answer:
Patsy signed with Decca at her first opportunity three years later.
