Just sang 'Ombra mai fu' in a stairwell

I was late for rehearsal, and the building was empty except for the echo. I didn’t mean to stop — just leaned against the stone wall between floors and let it out. The way the notes folded back on themselves in that narrow space… it felt like the aria had been waiting there all along. I’ve sung it a hundred times, but never like that. Not even in a hall. Something about the silence before and after made me remember why I do this. Still trembling. Maybe I’ll never be able to explain it.
