voice in F minor. A long episode of 29 measures follows, where the modulations are legion. For example, a sequence based on the three first notes of the turn theme is repeated eight times in a row starting in measure 47. Numerous dynamics are marked in the score: piano, forte, crescendo and decrescendo. This episode ends with the dynamic double forte decrescendo on a perfect cadence of G (D dominant seventh → G major), repeated twice identically. The G major chord becomes the dominant of the key of the second exposition. The second exposition of the subject begins at measure 70 in the left hand, in C minor, then in the right hand in G minor at measure 78. The same 29 episodic measures as before are heard, but transposed, then extended by 26 measures of new development, always using numerous sequences. A full measure of rest (measure 140) precedes a cadence in F minor, then F major, of which the A transforms into the tonic of the key B minor for the postlude, then the dominant of the cadence in E minor, followed by an E major chord, and concluding without transition on an F major chord. Ritornello Rossini wrote a brief instrumental passage, probably to establish the key of C major and the mood for the following Sanctus. The "Ritornello" and the "Sanctus" which follows are in effect in the same key of C major (both in 6/8). Sanctus The acclamation "Sanctus" (Holy) appears three times, sung by the choir, each time more intense than before. "Pleni sunt coeli et terra" (Full are heaven and earth) begins as a canon of the choir voices, beginning forte and ending softly. "Hosanna in excelsis" (Hosanna in the Highest) is sung by pairs of soloists in unison. For "Benedictus qui venit in nomine Domine" (Blessed who comes in the name of the Lord), the choir presents a soft melody in triplets. The sequence is repeated in different harmonic development and with the soloists taking over the "Benedictus" section. The movement culminates in a strong eight-part affirmation of "in excelsis". O Salutaris This movement was not part of Rossini's original version for two pianos and harmonium, but he inserted it in his version for orchestra. He transposed an earlier composition, which was originally in E major for alto, however as the alto soloist had to subsequently sing the Agnus Dei, it was
