Gustaf Wilhelm Petersson Hägg (November 28, 1867 – February 2, 1925) was a Swedish organist and composer.
He was appointed organist of Klara Church in 1893 and began teaching harmony at the Royal College in 1904.
It begins in six-eight in d-minor, with a folklike theme repeated with variants over sustained chords.
The story, one imagines, had a said beginning and a happy ending, but not without a bittersweet sense of something lost forever.
The constant pressure of a pipe organ makes it sound rather dull, although a skilled player may approximate the effect by a judicious use of the swell pedal.
