Swirls of Shamshir (Genshin Impact Sumeru Battle Theme / BPM 162 / 10/10)-Yu-Peng Chen

A 10-page level-4 solo-piano three-staff arrangement of Yu Pengchen@HOYO-MiX’s “Swirls of Shamshir / 狮尾之舞,” the Sumeru battle theme from Genshin Impact, arranged by Purrvoice热狗. At BPM 162, the seller rates it 10/10 and calls it their most difficult work of the year. The arrangement represents the opening sitar with grace notes and trills, percussion with staccato arpeggios and light bouncing textures, and strings and ney with trills and tremolos. Major challenges include interwoven polyphony and three-hand writing, wide chord leaps, rapid runs and hand changes from 2:57–3:23, fast octave passages that may be simplified by omitting the lower octave, and two-hand four-voice trills and repeated-note fingering after 3:53. The ending follows the Sumeru concert version rather than the in-game ending, with tremolos and the original crescendo–diminuendo shape. 拾廿七 and xwjcool123 reviewed notation details, with help from 抹茶味的鳄鱼. Chord symbols and lyrics are not included.
