It was first performed on Christmas morning, 25 December 1870,[1] by a small ensemble of the Tonhalle-Orchester Zürich on the stairs of their villa at Tribschen (today part of Lucerne), Switzerland.
[2] The original title was Triebschen Idyll with Fidi's birdsong and the orange sunrise, as symphonic birthday greeting.
[3] This theme, Wagner claimed, came to him during the summer of 1864 at the Villa Pellet, overlooking Lake Starnberg, where he and Cosima consummated their union.
This and other musical references, whose meaning remained unknown to the outside world for many years, reveal the idyll's levels of personal significance for both Wagner and Cosima.
[3] The original piece is scored for a small chamber orchestra of 13 players: flute, oboe, two clarinets, bassoon, two horns, trumpet, two violins, viola, cello and double bass.
