One dark night in that very November I fulfilled my last provincial institution engagement (at Dudley), and went back to stay the night, or what was left of it, at the Guest Hospital, with Dr. Orwin, my old schoolfellow, with whom I had the pugilistic encounter at the preparatory school on Haverstock Hill. He called me up at five o'clock the next morning, which was, if possible, darker than the night before, and packed me off to London to attend my first rehearsal, which was held in the refreshment saloon (without refreshments) at the Opera Comique. The course adopted with reference to the Gilbert and Sullivan rehearsals is as follows: The music is always taken first. The principal singers and the ladies and gentlemen of the chorus are seated in a semi-circle on the stage. A cottage piano is in the middle, and we are rehearsed as an ordinary choir would be. Sir Arthur Sullivan usually first composes the difficult choruses, especially the finale to the first act--an elaborate score. The quartettes and trios arrive next, and the duets and songs last. I have sometimes only received the tunes of my songs the week before production. The song in the second act of _Princess Ida_ was re-written, and I only got the music two nights before the performance. The difficulty then was, not in learning the new tune, but in _un_learning the old one. The greatest interest is evinced by us all as the new vocal numbers arrive. Sir Arthur Sullivan will arrive hurriedly, with a batch of MSS. under his arm, and announce the fact that there is something new. He takes his at the piano and plays over the new number. The vocal parts are written in, but no accompaniment. Mr. Francois Cellier listens and watches; and how he can remember for future rehearsal, as he does, the elaborate accompaniments and symphonies, with the correct harmonies, &c., from simply hearing Sir Arthur play the pieces over a few times, is to me astonishing. Mr. Gilbert will attend all these musical rehearsals: he takes mental notes of the style of composition, time, rhythm, everything, and goes home and invents his groups and business. For every piece he has small stages constructed--exact models of the Savoy Theatre--with set scenes. The characters are represented by little bricks of various colours, to distinguish chorus from principals, and ladies from gentlemen. Many a time he has shown me some future intended grouping, entrance, or general effect; and I must say it has been most interesting. No expense is spared to get the requisite accuracy; and I believe the little model of a ship, for the recent revival of _H.M.S. Pinafore_, cost £60. It is well known that Mr. Gilbert is an extremely strict man, and on all matters of stage business his word is law. All the arrangements of colours and the original groupings, with which the frequenters of the Savoy are so well acquainted, are by him.
