I wasn't really sure how to word this in a search. Maybe that's why I didn't find anything on this site or Google. My latest idea for the opening of my novel features a ghost doing... something. Right now, I'm thinking about making the ghost play the main character's guitar right in front of him. Thinking of ways to make that more interesting, I decided it would be fun to make it the ghost of Jimi Hendrix or some other late guitarist. I'm just concerned about what potential trouble that might cause. I know that using a real person in any significant way might be problematic, but this would be a pretty minor role. The ghost itself wouldn't be a major plot point; it would simply get the main character's mind thinking along the paths I need. I would say its appearances wouldn't take up more than a page or two. Also, the ghost wouldn't speak, attack, or do anything except play the guitar every time it makes an appearance. And finally, I wouldn't outright say that it's the ghost of Hendrix/etc., as that really isn't important. I'd just drop a hint here and there, perhaps have it play a Hendrix song as no one other than Hendrix could. I would think that would be okay, but I'd still like to make sure before I get too far into it. Thoughts?
