Blåsen nu alla, "All blow now!" (or Bloweth now all), is one of the Swedish poet and performer Carl Michael Bellman's best-known and best-loved songs, from his 1790 collection, Fredman's Epistles, where it is No. 25. It is a pastorale, based on François Boucher's rococo 1740 painting Triumph of Venus.
The epistle is subtitled "Som är ett försök till en pastoral i bacchanalisk smak, skriven vid Ulla Winblads överfart till Djurgården" (Which is an attempt at a pastorale in Bacchanalian taste, written on Ulla Winblad's crossing to Djurgården)
Carl Michael Bellman is the central figure in Swedish song, known for his 1790 Fredman's Songs and his 1791 Fredman's Epistles. He played the cittern, accompanying himself as he performed his songs at the royal court.
Jean Fredman is a fictional character and the supposed narrator in Bellman's epistles and songs, based on a real watchmaker of Bellman's Stockholm. The epistles paint a picture of the demimonde life of the city during the eighteenth century, where strong drink and beautiful "nymphs" like Ulla Winblad create a rococo picture of life (as in this Epistle, and in No. 28, I går såg jag ditt barn, min Fröja), blending classical allusion and pastoral description with harsh reality.
Blåsen nu alla is a song in eight verses, each of 15 short lines. The rhyming pattern is AABAB-CCDCD-EEEFF. It is in 3/4 time and is marked Menuetto (Minuet). The melody has the timbre "Waldthorns-stycke" but is origin beyond that is unknown.
