銀河をほどく指先 ― 星屑の跳躍

"銀河をほどく指先 ― 星屑の跳躍" (roughly "Fingertips that unravel the galaxy: a leap of stardust") is a September 2026 single by SeNA, the "AI diva" run by the producer BLUE. According to BLUE's production note, the aim was a song in which the piano itself tells the story: the intro opens on a forceful piano line, the right and left hands move independently, and the playing is pictured as unravelling a galaxy where past and present sound apart and then overlap. The chorus phrase "a leap of stardust" ties the piano's wide jumps to feelings leaping toward someone far away. BLUE says it was made with Suno v5.5 as an experiment in how far AI music can go with virtuoso piano, including movements a human pianist might find hard to play, and that the mix alternates between sections led by SeNA's voice and sections led by the piano. The release credits list GenerativeAI as lyricist and composer, and it came out through DistroKid.
