"The various groups of instruments in the orchestra were tolerably widely separated, especially the four brass bands introduced in the 'Tuba mirum,' each of which occupied a corner of the entire orchestra. There is no pause between the 'Dies Irae' and 'Tuba mirum,' but the pace of the latter movement is reduced to half what it was before. At this point the whole of the brass enters, first altogether, and then in passages, answering and interrupting, each a third higher than the last. It is obvious that it is of the greatest importance that the four beats of the new tempo should be distinctly marked, or else the terrible explosion which I had so carefully prepared, with combinations and proportions never attempted before or since, and which, rightly performed, gives such a picture of the Last Judgment as I believe is destined to live, would be a mere enormous and hideous confusion. "With my habitual mistrust, I had stationed myself behind Habeneck, and, turning my back on him, overlooked the group of kettledrums, which he could not see, when the moment approached for them to take part in the general _melee_. There are perhaps one thousand bars in my Requiem. Precisely in that of which I have just been speaking, when the movement is retarded and the wind instruments burst in with their terrible flourish of trumpets; in fact, just in _the_ one bar where the conductor's motion is absolutely indispensable,--Habeneck _puts down his baton, quietly takes out his snuffbox_, and proceeds to take a pinch of snuff. I always had my eye in his direction, and instantly turned rapidly on one heel, and, springing before him, I stretched out my arm and marked the four great beats of the new movement. The orchestras followed me each in order. I conducted the piece to the end, and the effect which I had longed for was produced. When, at the last words of the chorus, Habeneck saw that the 'Tuba Mirum' was saved, he said: 'What a cold perspiration I have been in! Without you we should have been lost.' 'Yes, I know,' I answered, looking fixedly at him. I did not add another word.... Had he done it on purpose?... Could it be possible that this man had dared to join my enemy, the director, and Cherubini's friends, in plotting and attempting such rascality? I don't wish to believe it ... but I cannot doubt it. God forgive me if I am doing the man injustice! "The success of the 'Requiem' was complete, in spite of all the conspiracies--cowardly, atrocious, officious, and official--which would fain have hindered it." BRAHMS.
