Alleluia! Laudamus Te is a hymn of praise without words, with the band serving as a single massive choir and, at times, individual sections, each performing as a separate choir. The music is based on three main themes, the first being a massive chorale in the brass, the second a long flowing line in the horns and woodwinds, and the third a quasi-fanfare figure first heard in the trumpets and then spreading throughout the other sections of the orchestra as it is developed.
