Par PART ARVO. 'I have developed a highly formalised compositional system, which I have been using to write my music for twenty years. Summa is the most strict and enigmatic work in this series', said Arvo Pärt in 1994. The neutral title itself embodies the essence of the content as the work is based on the text of the Latin Credo. The great simplicity of the piece masks its complexity. The underlying rules ensure that on the surface a cycle of continuous change is created while the deep structure possesses an order of stillness. Saale Kareda Originally written for four a cappella voices in 1977, the string quartet version dates from 1991. This edition adds a further version for trombone quartet./ Répertoire / 4 Trombones

When Beethoven visited the director of music at the cathedral in Linz, Franz Xaver Glöggl, in autumn 1812, the latter asked his guest to 'compose socalled Equali for 4 trombones for All Souls' Day [2 November]?. Beethoven readily complied - and it was to be his own funeral music. For in 1827 the Equali were sung in an arrangement for male choir as a 'dirge for Beethoven's funeral procession?. The original instrumental version is today a core work in the trombonist's repertoire. Our Urtext edition is based on the musical text in the Beethoven Complete Edition and contains a score and single parts (both in the original C and in modern bass clef). / 4 Trombones
