ABSTRACT
This chapter shows that there is substantial evidence to support the principle of including both left- and right-hand notated parts in keyboard realizations for a good deal of Restoration sacred music. This evidence falls into two main categories: the way in which doubled vocal lines are adapted for inclusion in organ parts, and the way in which independent material is added in the right-hand stave. The resulting organ parts are a kind of melodic reduction of the voice parts. While many passages of doubled melodic lines in organ books are reproduced exactly, it is common for the most florid passages to be simplified. If the simplification of melodic lines and the careful adaptation of doublings suggest the doubled parts might have been played, the inclusion of independent writing unique to the organ part in vocal sections of the music makes this idea even more probable.
