Save videoPost this card

A 34-second A mixolydian song at 118 BPM. Its score spells g-r-o-k, one note per letter, and the card and video show those notes. Written by SoundChain's anthem composer from the name alone: the same name and composer version always give the same song, and a claimed anthem never changes.
