18, there will be other 6 volumes dedicated to partially incomplete orchestral works. In order to avoid presenting a truncated musical text, and with a view to promoting the performance of said works, it has been decided to reconstruct the missing sections, albeit indicating editorial intervention clearly in the preface. In cases where several authoritative sources, both printed and manuscript, were used, the results of a comparative analysis are indicated only in cases of editorial intervention. Insofar as it was possible, we have attempted to avoid making changes in the original text, and have retained most of its characteristics. In the case of keyboard music, the original layout of the music between two staves has been retained.
All editorial intervention is listed in the critical commentary.
Original dynamic and agogic signs have been retained, and none have been added in cases where they were missing. In cases where it was found necessary, passing accidentals have been modified in accordance with modern usage.
