One Voice (Pure Piano Solo / Seller 8/10 / Level 2 / 5 Pages / Fast / Key Change / No Chords or Lyrics)-Rokudenashi

A faithful pure-piano arrangement of Rokudenashi’s “One Voice.” This fast five-page two-staff solo has no chord symbols or lyrics. The seller rates it 8/10: the high register can be challenging to sight-read, bars 44–51 combine fast note groups with a key change, and the hardest section in bars 60–75 has continuous right-hand octaves and left-hand leaps.
