The Grechaninov 'Passion Week' is a setting of thirteen pieces with texts in Church Slavonic meant to be sung individually over the period of Passion Week, the days leading up to the crucifixion and resurrection of Christ. The Russian Orthodox Church has a tradition of morning and evening services during Passion Week when the passion week's events are recalled almost in 'real time.' The music itself is generally slow, meditative, largely monophonic and almost trance-like. One notices that the usual number of singers in these two choirs has been supplemented by several additional basses, no surprise considering the long legato lines required of that section. Their low C's and even B's resound like the tolling of great bells throughout the work. One could almost surmise, if one didn't know, that this was the singing of a Russian choir, so noted for their deep basses, except that the blending and rounding of the choral tone is so very much more subtle than is generally heard from Russian choruses. The work is entirely a cappella and there are occasional soprano, tenor and baritone solos which consist mostly of chants sung against the main body of massed sound.
