Choralia provides three editions of training aids for Zadok the priest HWV258 by G.F. Händel, so as to best match the score edition used by the choir. Edition 1 is based on a version published on CPDL (edition by Philip Legge), edition 2 is based on Novello NOV 290217, and edition 3 is based on the old Novello edition available on IMSLP as IMSLP #255157. Editions 1 and 3 are full SSAATBB versions compliant to Händel's original, while edition 2 is a SATB arrangement (with Soprano divisi on few bars) by E. Silas.
