The Urtext instrumental part of this edition is laid out as a combined flute and bass part (featuring the original basso continuo figures without realisation). This manner of reproduction is oriented on the historical sources. Thus it is possible for an experienced continuo player to improvise a free accompaniment of his own to the sonata. Two copies of this dual part are included in this Henle edition, so that both players, flautist and accompanist, can perform from this combined musical text. In addition to the basso continuo figures, the score offers a historically appropriate basso continuo realisation that can be played at sight. In order to avoid page turns within the movements, the instrumental part is provided with a fold-out panel and a blank page.
