Choralia provides two 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), while edition 2 is based on Novello NOV 290217. Edition 1 is a full SSAATBB version compliant to Händel's original, while edition 2 is a SATB arrangement (with Soprano divisi on few bars) by E. Silas.
