guitar riffs. A riff is a cluster or sequence of notes or chords. A riff is used in a song. It can be repeated over and over again, but it may only be heard once, say for instance, in a lead guitar solo. Riffs can be minor decorative elements or they can be the basis of a song.
Bloodline's Florida production office is in Homestead, but the show does lots of location shooting in the Keys, where the story is set. It centers around the Rayburn family, longtime owners of an Islamorada hotel.
While it's true that some set locations aren't actually filmed in the areas the characters are supposed to be living in (like how Friends was actually shot at Warner Brothers Studios in Los Angeles rather than New York City), Bloodline is actually filmed almost exclusively on Islamorada, according to the Miami Herald.
