Read the following paragraph and extract the answer for the question: What had become an entirely new set of sounds according to Condon?

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...
