Utan svafvel och fosfor (TrV 159) is an a cappella work for male voice choir, written by Richard Strauss in 1889.

The Hofkapellmaster (chief music director) was Eduard Lassen (1830-1904), who welcomed the young Strauss and "readily acknowledged his artistic superiority.

"[1] Strauss finished orchestrating his tone poem Death and Transfiguration soon after his arrival, and on November 11 he premiered his Don Juan.

He spent many of his evenings, mostly in the company of Eduard Lassen, at the Künstlerheim, which he depicted to his father as "a frivolous means of passing the time, with a charming bar in an old smithy".

Utan svafvel och fosfor has been recorded by the Berlin radio chorus, with the Swedish lyrics, conducted by Robin Gritton.
