Q: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Passage: Like Green, who made particular mention of Beiderbecke's "amount of teaching," the jazz historian Ted Gioia also has emphasized Beiderbecke's lack of formal instruction, suggesting that it caused him to adopt "an unusual, dry embouchure" and "unconventional fingerings," which he retained for the rest of his life. Gioia points to "a characteristic streak of obstinacy" in Beiderbecke that provokes "this chronic disregard of the tried-and-true." He argues that this stubbornness was behind Beiderbecke's decision not to switch from cornet to trumpet when many other musicians, including Armstrong, did so. In addition, Gioia highlights Beiderbecke's precise timing, relaxed delivery, and pure tone, which contrasted with "the dirty, rough-edged sound" of King Oliver and his protégé Armstrong, whose playing was often more energetic and whose style held more sway early in the 1920s than Beiderbecke's.
Beiderbecke's playing - both as a cornetist and a pianist - had a profound effect on a number of his contemporaries. Eddie Condon, for instance, described Beiderbecke's cornet playing as "like a girl saying yes" and also wrote of being amazed by Beiderbecke's piano playing: "All my life I had been listening to music […] But I had never heard anything remotely like what Beiderbecke played. For the first time I realized music isn't all the same, it had become an entirely new set of sounds" "I tried to explain Bix to the gang," Hoagy Carmichael wrote, but "[i]t was no good, like the telling of a vivid, personal dream […] the emotion couldn't be transmitted."Mezz Mezzrow described Beiderbecke's tone as being "pickled in alcohol […] I have never heard a tone like he got before or since. He played mostly open horn, every note full, big, rich and round, standing out like a pearl, loud but never irritating or jangling, with a powerful drive that few white musicians had in those days."Some critics have highlighted "Jazz Me Blues", recorded with the Wolverines on February 18, 1924, as being particularly important to understanding Beiderbecke's style. Although it was one of his earliest recordings, the hallmarks of his playing are evident. "The overall impression we get from this solo, as in all of Bix at his best," writes the trumpeter Randy Sandke, "is that every note is spontaneous yet inevitable." Richard Hadlock describes Beiderbecke's contribution to "Jazz Me Blues" as "an ordered solo that seems more inspired by clarinetists Larry Shields of the ODJB and Leon Roppolo of the NORK than by other trumpet players." He goes on to suggest that clarinetists, by virtue of their not being tied to the melody as much as cornetists and trumpet players, could explore harmonies.
