G. Henle Verlag in 2013, the integrity of the cello version is justified. (At the heart of G. Henle Verlag's programme are the so-called Urtext Editions. They are characterized by their correct musical text, drawn up following strict scholarly principles, with an extensive commentary on the sources consulted – covering autographs, copies and early printings – and details regarding the readings.) On the "oral and written history" that Cesar Franck first conceived the sonata for cello and piano (before the commission from Eugène Ysaÿe arrived), Pablo Casals wrote in 1968, "... what I remember distinctly is that Ysaye told me that Franck had told him that the Sonata was intended for violin or cello. That was the reason for my taking it up and playing it so much during my tours." Antoine Ysaÿe, Eugène Ysaÿe's son, expressed in a letter that there is a version in César Franck's handwriting for cello.
