Claim: Zadok the Priest, written for SS-AA-T-BB chorus and orchestra, in the key of D major, prepares a surprise in its orchestral introduction through the use of static layering of soft string textures followed by a sudden rousing forte tutti entrance, augmented by three trumpets.
Evidence: Zadok the Priest is written for SS-AA-T-BB chorus and orchestra (two oboes, two bassoons, three trumpets, timpani, strings with three violin parts rather than the usual two, and continuo), in the key of D major. The music prepares a surprise in its orchestral introduction through the use of static layering of soft string textures followed by a sudden rousing forte tutti entrance, augmented by three trumpets.
