Bard City Blues by Nathaniel Webb

Music, magic, mystery, drinking, family, and gelatinous cube. Gally Chaparral is a highland girl with a dream: move to Lackmore, join the Bardic Guild, and get a gig at a fancy tavern on Symphony Hill. Unfortunately, becoming a bard isn't so easy. No good tavern will hire a student, her teacher is a jerk, and the only job she can find is washing dishes at a bar at that seems to have recently been a dungeon. When Gally auditions as her tavern's new bard, things start looking up. But her first show is ruined when the owner accuses Alix, a beautiful but obnoxious postal rider, of destroying a valuable painting. Now, to keep the gig, Gally must prove Alix's innocence. But there's more to the mystery than the loss of a painting, and being forced to work with Alix has Gally wondering if this brassy delivery girl is really as bad as she seems...
