Friend was given a guitar with what looks like Chinese handwriting on it (Characters identified: 茶杏銅鑼) Could anyone who's more knowledgeable in language confirm that this is Chinese? My friend knows Japanese, and he says it's definitely not Japanese (unless he's mistaken).

If it is Chinese, could someone translate it to English for me? I've tried many different optical character recognition sites, and none can figure any of the characters out.
They are written in traditional Chinese: 茶杏銅鑼, which translated verbatim to Tea, Apricot, Copper, Gong.The four words together do not resemble anything meaningful. I did a google search with the exact four words but cannot find anything related.
