''études-tableaux'' by Rachmaninoff, Op. 33|the second set|Études-Tableaux, Op. 39}}
The '''''Études-Tableaux''''' ("study pictures"), Op. 33 is the first of two sets of piano études composed by Sergei Rachmaninoff.
These sets were intended to be "picture pieces", essentially "musical evocations of external visual stimuli". Rachmaninoff did not disclose what inspired each piece, stating: "I don't believe in the artist that discloses too much of his images. Let them paint for themselves what it most suggests." However, he willingly shared sources for a few of these études with the Italian composer Ottorino Respighi when Respighi orchestrated them in 1930.
