His old friend and former teacher Camille Saint-Saëns wrote to him in 1917, "Ah! if there is a god for the left hand, I should very much like to know him and make him an offering when I am disposed to play your music; the 2nd Valse-Caprice is terrible in this respect; I have however managed to get to the end of it by dint of absolute determination."
O seu amigo e antigo mestre Camille Saint-Saëns escribiulle en 1917: «se hai un Deus para a man esquerda, encantaríame coñecelo e facerlle unha ofrenda antes de dispoñerme a tocar a túa música; o segundo Vals-Capricho é terrible neste sentido; con todo, conseguín chegar ao final a forza de absoluta determinación».
