SANCTUS / Henry / S.A.T.B., a cappella MARS HILL COLLEGE CHORAL SERIES SANCTUS OTTO HENRY ED-SACRED-SACRED- SAC ED- SACRED“ SAC SED SAC RED- SACs ... Program Note The Sanctus is an aleatoric mass movement in which the pitches are selected by the performers and the durations are cued by the conductor. The score is divided graphically into three pitch boxes, high, middle and low. The numbered vertical arrows are conductor’s cues for entrances, cutoffs, pitch changes. and dynamic changes. In the first section, no tempo or duration is specified except by horizontal spacing. Vertical arrows joined by a bar are to be executed in quick succession. At the beginnning, the pitches of the four soloists (SATB) are individually selected according to the positions of the lines in relation to the pitch boxes. At 2, the respective choral sections enter individually at the unison. At 3, the choral sections glide at individual rates above and below the central pitch sustained by the soloist. The conductor may want to double the central pitch after it has been established by the soloist. The choral parts should dwell on the central pitch from time to time, and should progress no further than a major third above and below it. The central pitch changes at 11. The basses leap up an octave, the altos rise a half-step, the tenors go down a whole tone and the sopranos go down a fifth. Shortly after conductor’s cue 15, the basses begin a rapid fluctuation above and below the center pitch, agitato. The other parts repeat this in succession. At Al, the basses intone in unison on the center pitch while the other parts begin a gradually descenting glide to the lowest note ( P.4), out of which the soprano and tenor and later the alto and bass glissando upwards into the high range. At letter B (p.7), a measured 4/4 has to be maintained for synchronization of the parts. In this section, the beat is equal to the single square box. For example, in the beginning alto part, ‘“Be” is two beats, ‘‘ne”’ is one beat, “dic” is six beats, etc. At. B6, the conductor once more cues the durations (“Hosanna’’, etc.) SANCTUS from the MASS for mixed chorus and soloists 5 OTTO HENRY (1973) 4 5 6 7 5.39 SOLO XO LS) SORRANOP | ca — sas Pp high SOLO range TENOR y° 2) apes ~ oD sa ae Ppp — el, i i me eee ae ‘a o 2 _ ‘ 1 2 3 ALTO sa > > ? > > > > f¢ 40 mi ne De us Sa ba oth ff ple ni sunt caz |j — ff et ter ra \ BASSES measured unison chant On solo’s Pitch (15) 16 / ee altos —— z ° BASSES Join u-) y fff lowest : note possible solo sop. solo ten. dim. ¥ & cel sis ff pe ND, cla measured 4 Qquasig tenors 4 bass¢s be —S)
