The Gnomish name of Timpinen the flute player, Tinfang plays music so beautiful that it causes whoever hears it to fall forever in love with starlit nights and summer evenings. In "The Book of Lost Tales" it is said of him " ...'he is a wondrous wise and strange creature, and he fared away hither with the Eldar long ago...always ahead piping strangely or whiles sitting aloof. Now does he play about the gardens of the land; but Alalminórë he loves the best, and this garden best of all. Ever and again we miss his piping for long months... But on a sudden will his flute be heard again at an hour of gentle gloaming, or will he play beneath a goodly moon and the stars go bright and blue.'" (Part One, p. 94)

Though mentioned little, Tinfang Warble apparently existed in Tolkien's mind from the very beginning. Tolkien also wrote two poems about Tinfang, and these appear in "The Book of Lost Tales: Part One", pages 108-109.
