Modal RunsC#aug Chord (Augmented)
The augmented triad raises the 5th a semitone — root, major 3rd, sharp 5th — erasing the interval that normally anchors a chord. The notes of C#aug are C#, F, A.
With no perfect 5th, it never resolves anywhere in particular; it just hangs, dreamlike or unsettling depending on context.
