After preparing hisScenes historiquesop. 66 for print in spring 1912, Sibelius had many grand plans but had to turn towards more profitable piano works first, due to his financial situation. Within only one month, he wrote theThree Sonatinasop. 67 in June 1912, which were published by Breitkopf already in November the same year. Although by his own accounts he did not like writing for piano and only doing it for income, he told in 1948 Erik Tawaststjerna that he regarded the Sonatinas among his best chamber music and considered them equal to his string quartet Voces intimae.
