Everything analysis can say about what is sounding, in one card: the chord symbol with its alternatives, note names and the raw set encoding, the Forte set class, the interval-vector chart inline, and a self-consonance meter. The symbol answers what you are playing; everything below answers why it sounds like that. Chord naming is dependency-free — a ranked search over a quality dictionary that reads inversions from the bass note.
