Draft a dialogue where a ghost character teaches a living person to complete its unfinished opus.
Music and art have long been seen as elements that could bridge the gap between the living and the dead. Establish a rapport between the ghost and the living artist. The unfinished piece of work carries emotional heft and historical resonance for the specter, which should be mirrored in the dialogue. Explore how the ghost communicates musical concepts or artistic visions, adds sentimental or historical context, and gradually entrusts the mortal with its unfinished composition.
