It is well established that Georgian chant uses modes in the sense of melodic formulae. But some have referred to diatonic modes of one kind or another in Georgian sacred and/or folk music. Whether such modes are conceivable depends on the tuning system, which is a matter of dispute. To address the question of modes and indirectly the question of tuning, I analyzed statistical properties of harmony and voice leading in a collection of Shemokmedi School Georgian chant as sung by Dimit’ri P’at’arava. This preliminary study found no clear differences between passages with different cadence tones and thus no support for the hypothesis of diatonic modes. On the contrary, all passages shared suggestive, systematic patterns of melodic and harmonic tendencies. These patterns are consistent with a melodic and/or harmonic system of equal or nearly equal steps.
