As Gerald Strang pointed out in his 1968 catalogue essay, music composition can be a lot like computer programming: "If I write a series of notes and I say this passage is to be played mezzo forte
by the oboe, with certain particular kinds of attacks and certain phrasing ...
And in this area, I think, the Singers could have brought more tonal variety and dynamic contrast to certain choruses, at least in the oratorio's first part: Too often in that half, the choral sound, movement-to-movement, was homogenous and dynamics rarely sounded less than mezzo forte
Sub-elements and common terms and instructional terminology may include: volume, dynamic terms (pianissimo, piano, mezzo piano, mezzo forte
, forte, fortissimo, etc.) balance, dynamic contour, crescendo and decrescendo (and the understanding of how to use this technique to shape phrases for the fundamentals of expression), tension/release, terrace dynamics, subito, fortepiano, pianoforte, sforando piano, intensity, nuances, calando, niente, dal niente, smorzando, sotto voce, rilievo, calando, morendo, perdendo, accent, marcato.
