6, are a set of two pieces for piano and violin composed by Sergei Rachmaninoff in 1893.

The Morceaux de salon are similar in scope and structure to the Pieces for cello and piano, Op.

The Morceaux de salon consists of a Romance and a Danse hongroise (Hungarian dance).

Robert Matthew-Walker writes that "such is the composer's mastery of violin writing (though he may well have enlisted Conus's assistance in this regard) that one regrets that he did not leave a more extended work for the instrument".
