Commentary by Left Brain and Right Brain. LB: "The 1st and 3rd movements are in B Minor and extremely chromatic. By contrast this Andante cantabile – in A Major, C-Sharp Minor and E Major – is harmonically very simple. One self-imposed challenge was to create 2 themes of 2 phrases each, in which the 2nd phrase inverts the 1st. Another challenge was to harmonize each theme with further inversions of itself. The extremely simple harmonies permit these thematic manipulations with the greatest of ease." RB: "As if that weren't enough gymnastics, in 1 or 2 places I also play both themes in counterpoint with each other. One more challenge was to avoid accidentals at all, but doggone it, a few sneaked in anyway. Looks like I was none too sharp eh? Anyway my favorite section is smack dab in the middle, with some blissfully ecstatic music." LB: "Another consideration was that B Minor has 2 sharps, whereas B Major has 5 sharps. Therefore this movement alternates 3 and 4 sharps. It was completed in May 2004 in Washington, DC."
