While Tavener's earliest music was influenced by Igor Stravinsky and Olivier Messiaen – often invoking the sound world of Stravinsky, in particular "Canticum Sacrum", and the ecstatic quality found in various works by Messiaen – his later music became more sparse, using wide registral space and was usually diatonically tonal. Tavener recognised Arvo Pärt as "a kindred spirit", and shared with him a common religious tradition and a fondness for textural transparency. Tavener's later music moved away from the transparent simplicity of the 1980s towards a much more harmonically saturated style, in parallel with his pan-religious interests. Such works as Atma Mass (2003) and Requiem (2008) show this particularly well.
