Singing On My Own: what your voice is in for
On My Own is the great unrequited-love soliloquy of the modern stage, and its researched range, B2 to C#5, tells the structural story: it begins in a low, spoken-adjacent register, warms as the fantasy builds, and peaks in full-belt heights before deflating back to earth. The deciding moment in this Les Misérables showcase is the climactic belt sequence and, crucially, the quiet lines after it: the comedown is where the acting either completes the song or abandons it.
The technique is belt-and-release: a sustained, chest-driven climax followed immediately by controlled, intimate soft singing on tired breath, the full theatrical cycle in ninety seconds. Tenors reading the stored span sit one under the floor and four over the ceiling; in practice this is mezzo-belter territory onstage, with the lowest phrases delivered as speech. Altos face the peaks six semitones over their band ceiling and should transpose down two or three, a routine accommodation in auditions. No verified key is stored on this entry, so build from your best sustained belt note and protect the comedown. Companion piece: I Dreamed a Dream.
Practice cue: rehearse the climax and the quiet aftermath as one inseparable unit, never separately. Auditioners hear a thousand good belts; they remember the ones that land softly.
