Comparing Op. 7 and Op. 109
Listen again to Op. 7 and then to Op. 109. (If you are short of time, just listen to the last movement of each.) One could argue that they are different in almost every respect, but which differences strike you as most significant, most meaningful?
It seems that Beethoven had given more specific direction to the performer to play the variations a certain way, i.e. perhaps as he would have played them himself indicating a more personal approach to performance than in the past. But perhaps it is also an extension of the trend that composers such as Mozart and Beethoven had started making sure that performers do not play with abandonment per Baroque performance practice. Setting the trend of for composers to be more directive e.g. Debussy many changes of tempi and more directions perhaps?
