Twilight is the time between day and night when the sun is below the horizon, but its rays still light up the sky.
Dusk occurs at the darkest twilight stage, or at the end of astronomical twilight, after sunset and just before night. Most stars and other celestial bodies can be seen during this phase. It may be challenging to distinguish astronomical twilight from the nighttime to the naked eye, especially in areas with light pollution.
We can sometimes see a light that shimmers, sparkles, or sheens through the dusk. It’s like the surface shimmers, like a landscape glowing in dusk’s soft light.
Astronomical dusk is the instant when the sun’s geometric center is 18 degrees below the horizon in the evening. It marks the beginning of nighttime and the disappearance of the last shimmer of natural daylight.
In Norway, the sun’s path makes a low angle with the horizon because of high latitudes, making the twilight phases long-lasting.
Dusk Shimmer consists of 4 movements. All of them are in different ways related to sonata form.
A string quartet is somehow a perfect format with a wonderfully rich history, and in this piece, I wanted to investigate some of the classical concepts.
I have imagined light and different stages of light while writing this piece. I was in the world of the midnight sun while writing parts of the material, but in the dark winter while finishing. I think it shaped the sounds and my choices. In grey winter, gleams of glittering light can be more fantastic and more appreciated! But the dusk itself can also be beautiful.
