- O Elbereth Starkindler
(white) glittering slants down
sparkling like jewels
from [the] firmament [the] glory [of] the star-host!
To-remote distance far-having gazed
from [the] tree-tangled middle-lands,
Fanuilos, to thee I will chant
on this side of ocean, here on this side of the Great Ocean!
The rest of it is not saved but it is possible that Oh Snow-white is a Westron translation or variation of this aerlinn. Variations of this hymn are sung throughout the book, such as the very last one written down:

Donald Swann wrote music for this song, which can be found in the book The Road Goes Ever On where Tolkien gives also a Tengwar text of the poem in the Mode of Beleriand given above; it is also found on the accompanying CD of the latest version.
A different musical version was recorded by the Tolkien Ensemble. The first version cited above can be found on their album A Night in Rivendell, and takes the form of a chant sung by a female soloist. The second version can be found on the album At Dawn in Rivendell.
Another musical version was composed by the Russian Tolkienite band Aire and Saruman.
