 The autograph of the work was acquired in 2014 by the Max-Reger-Institute from the dissolved archive of the Schott Verlag in Mainz.Susanne Popp, a Reger scholar and the director of the institute, notes that in Opus 6, Reger noticed reading the proofs from the publisher that his handwriting was a problem because of many dynamic markings in addition to many notes, and that he therefore began to write the dynamics in red, a habit he kept for life.The autograph was presented in an exhibition of the Baden State Library in 2015, in preparation for the Reger Year 2016.
