Life of Mozart

Thus beforethe Dies irse was finished he had composed the Offertorium,of which the two movements, Domine Jesu Christe andHostias, were left virtually complete in the same state asthose mentioned above.It will now be understood how Mozart, going through thescore, either at the piano or the desk with his pupil Siissmayr,would discuss the various points of the instrumentation,would encourage him to make suggestions, and explainhis own ideas and intentions, so that Siissmayr would inmany respects have formed a lively image in his mind ofwhat the completed score would be, and would often be ablefaithfully to reproduce Mozart's own intentions.
