Symphony in 12 Movements
Like Alfred Schnittke, Gubaidulina (born in 1931) has a strong current  of mysticism in her work; her compositions seem to hint at "higher"  levels of perception or cognition.Stimmen ... Verstummen(1986) is a  symphony in 12 movements that race up and down the scales--at times in  opposition to one another--in compact, sometimes extroverted sound clusters. In  between these flights, the composer repeatedly returns to a stabilizing D-major  triad, which allows the work to cohere. This composition's elements are  discordant, but its eventual symphonic argument emerges intact and clear. This  is perhaps Gubaidulina's greatest work.--Paul Cook
