In all, Polish composer Krzysztof Penderecki completed eight symphonies, and in 2013, to celebrate his 80th birthday, there appeared a box set of recordings billed as his “complete symphonies,” all conducted by their composer. But while that “complete” set included Symphonies Nos. 1-5 and 7&8, it was missing No. 6. The reason? Although Penderecki had begun work on his sixth symphony years earlier, it remained unfinished when the set was issued.

Fast forward to today’s date in 2017 for the out-of-sequence premiere of Penderecki’s Symphony No. 6, given in China by the Guangzhou Symphony Orchestra. The venue was apt, since the symphony was subtitled Chinese Poems, and included settings for baritone and orchestra of eight ancient Chinese poems — with a Chinese instrument, the erhu, providing solo interludes.

Curiously, Penderecki chose to set German translations of the Chinese poems, translations published back in 1907 in the same collection Gustav Mahler had sourced for his unnumbered song-symphony Das Lied von der Erde, the Song of the Earth. And it’s probably no coincidence that Penderecki’s Symphony No. 6 sounds very much like he was trying to channel both the spirit and sound world of Mahler’s early 20th century song-symphony into own his 21st-century one.
