Julia Thomsen builds the entire piece on a single ostinato, and the first thing worth noting is how little it resembles conventional piano writing. The figure sits high in the instrument’s upper register, each note struck lightly and released almost at once, so the attack dominates and the sustain barely registers. The effect is closer to a celesta or a music box than a grand piano, and I suspect that was entirely deliberate.
Anyone who knows Satie’s Gymnopédies, or the early piano works of Philip Glass, will recognise the method. Repetition here is not a device for building tension; it works the other way, gradually dissolving the listener’s sense of forward motion until the pattern becomes something closer to texture than melody. By the third or fourth cycle I had stopped following it consciously, which is precisely the point.
Sophie Bickerdike enters over this with a vocal line pitched in a comfortable middle tessitura, sung with minimal vibrato and very little dynamic variation. It is a disciplined performance. She resists every opportunity to climb or swell, and the line moves in long, unhurried phrases that sit across the bar lines of the piano figure rather than on top of them. That slight rhythmic independence between voice and keyboard gives the piece its sense of suspension; the two parts coexist without ever quite locking together.
I would have welcomed one harmonic shift somewhere in the second half, a single change of colour to reframe the ostinato before it returns. Its absence is a defensible choice, though, and the piece is short enough that the stasis never becomes wearing. Arvo Pärt has built a career on trusting stillness to carry a listener, and Thomsen and Bickerdike show a similar confidence.
“Like A Light Bulb” belongs less to the concert hall than to the late evening listening room, and heard in that setting it is a quietly accomplished piece of work. It is out now on all major streaming platforms.
