Strut Crystal
A dorian · 87 BPM · 9.8s · i – VII – i – VIImp3
A 9.8-second A dorian song at 87 BPM. Its score spells f-u-r-l-a-i, 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.
