My father was a violinist, my mother a pianist. I was born into a world of music... The practicing of my father's pupils accompanied every thought and action of my childish life.... Then when I was thirty [c. 1906], my career as musician was brought to an end by Vollard [art-dealer in Paris] who bought all the pictures I possessed, pictures which I had painted over several years with unbounded enthusiasm during such hours of freedom as I was able to spare between [music]-lessons to my pupils.
