The pleasant little town of Portland has reason to congratulate itself, first, on being the birthplace of such a composer as Mr. Paine; secondly, on having been the place where the first great work of America in the domain of music was brought out; and thirdly, on possessing what is probably the most thoroughly disciplined choral society in this country. Our New York friends, after their recent experiences, will perhaps be slow to believe us when we say that the Portland choir sang this new work even better, in many respects, than the Handel and Haydn Society sing the old and familiar "Elijah"; but it is true. In their command of the pianissimo and the gradual crescendo, and in the precision of their attack, the Portland singers can easily teach the Handel and Haydn a quarter's lessons. And, besides all this, they know how to preserve their equanimity under the gravest persecutions of the orchestra; keeping the even tenour of their way where a less disciplined choir, incited by the excessive blare of the trombones and the undue scraping of the second violins, would be likely to lose its presence of mind and break out into an untimely fortissimo. No doubt it is easier to achieve perfect chorus-singing with a choir of one hundred and twenty-five voices than with a choir of six hundred. But this diminutive size, which was an advantage so far as concerned the technical excellence of the Portland choir, was decidedly a disadvantage so far as concerned the proper rendering of the more massive choruses in "St. Peter." All the greatest choruses--such as Nos. 1, 8, 19, 20, 28, 35, and 39--were seriously impaired in the rendering by the lack of massiveness in the voices. For example, the grand chorus, "Awake, thou that sleepest," begins with a rapid crescendo of strings, introducing the full chorus on the word "Awake," upon the dominant triad of D major; and after a couple of beats the voices are reinforced by the trombones, producing the most tremendous effect possible in such a crescendo. Unfortunately, however, the brass asserted itself at this point so much more emphatically than the voices that the effect was almost to disjoin the latter portion of the chord from its beginning, and thus to dwarf the utterance of the word "Awake." To us this effect was very disagreeable; and it was obviously contrary to the effect intended by the composer. But with a weight of four or five hundred voices, the effect would be entirely different. Instead of entering upon the scene as intruders, the mighty trombones would only serve to swell and enrich the ponderous chord which opens this noble chorus. Given greater weight only, and the performance of the admirable Portland choir would have left nothing to be desired.
