Psalm 117 - A Dominum factum est istud (314;313.01) Johann Schein set two verses from Psalm 117 as an antiphonal choral piece in Latin. A Dominum factum est istud (This is the Lords doing) has been wonderfully arranged for 8-part mixed Brass Ensemble by Kenneth Biggs. The work of almost 5 minutes in length is appropriate for moderately advanced performers and Mr. Biggs has supplied many substitute parts so the work may be performed by any number of Trumpets (in C or B-flat), Flugelhorn, Horns in F, Trombones (in bass clef and alto clef) and Tuba. There are 15 parts in all, and the ranges are quite moderate, so this is a perfect antiphonal work to introduce to less experienced performers. This arrangement works very well with mixing and matching of all the different instruments together.
