live from a concert called "Amantes sunt Amentes," which meeans lovers are lunatics. the lunatic in this case is Schumann; these variations were written as an homage to him and clara after he attempted suicide and was committed to an ayslum. here is what i wrote about this very special piece in the program notes:
A piece that fascinated his closest friends and a favorite of scholars and critics, Johannes Brahms’ Variations on a Theme of Schumann are a set of variations of uncommon richness in their multiple layers and hidden messages. Written in 1854, they are based on a theme from Schumann’s Bunte Blätter, op.99 that was also Schumann’s code for the name of his wife Clara (C-B-A-G#-A). Brahms wrote his set in a fit of inspiration (or desperation) after Schumann, failing a suicide attempt, was committed to an insane asylum in Endnich.
At their heart, the variations are a rhapsody of sadness. Many of them take the form of a dialogue, suggesting a male and female voice; the Clara theme is woven throughout like a cantus firmus; and stunning canons abound - four total, all using different techniques.
Spiritually, the dialogue may be the defining characterstic of this piece. As Charles Rosen pointed out, each variation appears to be modeled in some way on a piece or specific musical idea by Schumann. Not only was Brahms varying the theme, he was writing variations on Schumann’s life work, conducting a dialogue with the former mind, now lost to mental illness, of his mentor and predecessor.
Brahms’ biographer Jan Swafford called the musical symbols in this piece “cabalistic,” which may explain its powerful attraction to those who love to study music in private. Essentially, the prevalent mood is as intimate as the later Klavierstücke, rather than the extroverted buoyancy of other variation sets such as Handel or Paganini Variations.
