Monotonic scaleA monotonic scale is a musical scale consisting of only one note in the octave. Having a deliberate fixed note, the monotonic is still a musical form rather than a total absence of melody. The monotonic stands in contrast to more common musical scales, such as the pentatonic (five notes) and modern, common Western heptatonic and chromatic scales.
Liturgical usageEarly Christian liturgical recitation may have been monotonic. Charles William Pearce speculated that the monotonic psalm tone might have been an intermediary step between spoken recitation of the Psalter and melodic singing:The Annotated Book of Common Prayer similarly notes that (according to Saint Augustine) Saint Athanasius discouraged variance in note in liturgical recitation, but that eventual modulation of the note led to the development of plainsong.
In Māori Christian services in Auckland, New Zealand, the Ten Commandments and the Psalms are sung in a responsorial style called waiata (the Māori word for song), with monotonic chanting alternating between the minister and the congregation. Some of the congregation may sing at the interval of a third above the others, and sometimes a few of the women will add a fourth below, producing a constant second-inversion triad. The end of each phrase is marked by a descending glissando.
