No, that's this, which is, after all, child's play:It's probably the easiest to follow serial piece ever if it is serial.
No, that's because those things were already a part of Schoenberg's style (where they derived from Beethoven, Mahler, and Wagner). I find Schoenberg's music is very lyrical, though, in the sense that all of the lines sing and have melodic contour.You certainly can write otherwise quite traditional and lyrical 12-tone music, but I suppose in such context the method may seem like a straightjacket. Is this why the method is associated with those extreme leaps and jagged rhythms?
There's actually no Mahler influence in the Gurrelieder (except in the orchestration of Part 3), contrary to popular belief. When he composed the work in 1900-01, he had only heard Mahler's First Symphony and despised it as worthless. He had subsequently declined the opportunity to hear the Vienna premiere of the Fourth because he was convinced that it would itself be terrible. Only with a performance of the Third a few years later did he convert, and according to a gushing letter he wrote to Mahler after the event, the piece struck him "like a thunderbolt." After that he revered Mahler as the most perfect composer of his age.I can hear Wagner and Mahler throughout this.
