The harp is a lie.

[PSxpert2011]

I think its bow/harp. Like when you want to use a bardspell(song) you kinda "fling" the notes away like arrows.
Thats why there's a grip on the harp itself, right in the middle.
Pretty cool when you think about it!

OMG I just answered to a post right above yours with almost the same IDEA,rofl! Good way to make peace with the "Harpers". I still think it's a composite bow with a design to throw you off. Crazy Japanese- making fun of the western thought patterns, intellect and rationality XD ... artist can be so abstract but very clear with their compositions and designs.
