Below are computer simulations of the Oratorio. Not real recordings, but they do give an impression of what it will sound like.
Part 1, the Preamble...
... is one of the largest parts. 8-9 min's, scored for all four soloists, mixed choir and full orchestra; and it sounds something like this...
... is a trio (Mezzo-Soprano, Tenor, Bass), with choir, narration and chamber orchestra
... is the Soprano solo, with wind-quintet and string-orchestra. The four solo's are the shortest parts, each time less than 2 minutes long. Short, but no less important.
...is scored for all four soloists and chamber orchestra. Sounds like this...
...is a duo for Soprano - Tenor, with chamber orchestra and a special role for bass-marimba and bass-clarinet. High pitch vocal soloists, low pitch instrumental soloists.
...is the first choir-solo, with a cor anglais solo and accompanied by the string-orchestra
...is sung by the four soloists accompanied by a chamber orchestra
...employs the triangle, one of the least often used soloists, along with a viola for an important solo. Sung by the four soloists this part is then supported by a chamber orchestra.
...is a duo for the Mezzo-Soprano and the Bass soloists. Joining them is the mixed choir and a chamber orchestra.
...which is the Bass solo, accompanied by a woodwind quintet and percussion
...is a trio for the Soprano, Mezzo-Soprano and Tenor soloists. Here they are accompanied by a chamber orchestra emphasising the lower intruments (e.g. alto flute instead of the concert flute).
...is another trio but now giving the stage to the Soprano, Mezzo-Soprano and Bass soloists. Again accompanied by a chamber orchestra, though this time it is rather the higher intruments (e.g. piccolo and not the regular concert flute).
...is the Mezzo-Soprano solo, accompanied by vibraphone, harp, celeste, and double bass.
...is the third and last choir-solo, with the brass- and string-orchestras plus percussion
... is the Tenor solo, assisted by a french horn solo and the woodwind- plus string-orchestras
...is a trio for the Soprano, Tenor and Bass soloists. Joining is also the full mixed choir and a chamber orchestra
Accompanied by the woodwind- and string-orchestras, this part employs all the four soloists plus the women's choir.
Being the last part it employs everyone - full symphony orchestra, full choir and all the four soloists.
