For the Brahms First Symphony, Ashkenazy used the orchestra's fine clarity to illuminate the ideas in the score, loyally keeping a certain respect for the composer, though his conducting was in no way conservative or overly careful, enough so that it made me wonder again why some people call Brahms 'autumnal.' Perhaps this clarity of playing which articulates each note also allows Ashkenazy the fine control he needs for his well-defined ideas of interpretation which come across to the listener so plainly.
While a piano soloist has special control over their music, and complete polyphonic music at that, that is to say melody, harmony and range and all the parts or 'voices' where contrapuntal, and this endows the pianist also with solitude, there is a romance fundamental to piano music, the two hands creating a relationship and complementing each other, at the very least in register. Piano music for 'four hands' is then even more romantic, the chamber music-wise relationship of the two musicians, the complexity of the music and the ease with which it can slip into a thick intensity, a knife's edge from chaos, the twice infinity combinations of expression, unanalyzable on the fly and loss of a degree of control, leave even more to faith, and make this music an especially creative performing art form. This is partly why Mozart called the organ the 'king of instruments,' though a pair of pianos of course has fewer stops, it is capable of greater percussion and so a peculiar rhythmic sense which the organ can't express in the same way. On top of all this, Pascal and Ami Rogé chose some very difficult music for this concert, which showed off their technical ability, but more importantly gave them the material to produce a vivid operatic sound, singing duets in their fingers while playing the orchestra part as well.
