either of the techniques known as quarter-chanting and half-chanting. In quarter-chanting (which is more true to the structure of the Hebrew poetry), the side that starts (usually decani) sing the first quarter of the chant (and thus the first half of the verse). The side that did not start (usually cantoris) then sing the second quarter of the chant (and thus the second half of the verse). This sequence then repeats. In half-chanting (which is more true to antiphonal singing in the Gregorian style), decani sing the first two quarters of the chant, and cantoris the next two quarters (so that each half-choir sings a whole verse at a time). With antiphonal singing, the first two verses, the Gloria and perhaps the last two verses are often sung by the whole choir. A few choirs elaborate further, e.g. by having some verses sung by soloists, trebles only, alto/tenor/bass only (with the treble line transferred into one of the other parts) or one part or soloists singing the melody while the rest of the choir hums. Occasionally some or all trebles may sing a descant; this usually happens only in the final verse of the psalm or the Gloria.
