this book reminds me a little of two books I've read. first, I'm hearkening back to Cobalt by Nathan Aldyne, because the murder sort of intrudes upon a very touristy place, right in the tourist season, so you have all this skullduggery going on around a lot of people who are there just to have a good time, or people there trying to run touristy businesses while being ensnared in the police inquiries, questioning, etc. two very different things that cause stress and frenetic activity bumping up against each other: tourist stuff meets murder.
I'm also flashing back to The Spoilt Kill by Mary Kelly, which featured a "town as extra main character/town's source of livelihood as integral to the plot, and clues, and placement of the corpse"...though that was a bleaker town, with all the smoke in the air due to the pottery industry (not yet overhauled for health and safety...). plus, the style of the books seems similar, though this Joss novel is a bit wittier.
of course, Funeral Music is hardly a full-on retread of anything I've read before, thanks to Bath, and the music angle, and its own cast of intriguing characters, especially Sara.
