The ivory keys let out a sorrowful narration as I caress them through another Nocturne. It begins with a cadence of demanding chords followed by a humbling repetition, and then quietly enters a low melody until it broadens into a fortississimo. My fingers graze and a dizzying trill rushes into a sudden halt -- and the melody seems to sigh before it takes a few light steps to fall into another series of contemplating phrases.
