composed by Arcadelt
Jacques Arcadelt (1505-1568) was a French composer in late Renaissance period, who composed madrigals and chansons. This piece, "Il bianco e dolce cigno (The white sweet swan)", is his most famous madrigal singing about dying swan. The original text translated to English is as follows - quoted from CPDL, Choral Public Domain Library.
The white and sweet swan dies singing,
reach the end of my life.
Strange and different fate,
that he dies disconsolate and I die a blessed death,
which in dying fills me full of joy and desire.
If in dying,
were I to feel no other pain,
I would be content to die a thousand deaths a day.
