Op. 147 - Harmony Parts-Diabelliâ??s church music has unjustly largely fallen into oblivion. In his 'Pastoral Mass in F' the Austrian composer of the Biedermeier period succeeded in achieving a balance between artistic aspirations and a form suitable for practical performance. With a duration of about 30 minutes the work is of easy to medium difficulty and is therefore extremely suitable for amateur choirs with orchestra. The 'Pastoral Mass' is suitable for performance both at Christmas time and beyond.
