The next concerto on my evolving list is the Piano Concerto No. 4 by Beethoven. I was all set to do a post on it, but then I remembered that I already did one back in Nov. 2011. Here is the link.
I wouldn't add too much to it today except to note that the opening phrase in the solo piano--yes, this piano concerto uniquely begins with the entire first phrase in the solo instrument--is answered with the dominant of the relative minor: by B major, in other words. E minor is also the key of the middle movement which is possibly the most extraordinary concerto movement ever written. I think I will just refer you back to this earlier post instead of doing it all again. I have gone back and updated the video clips.
I want to mention that next week I will be delving into the Beethoven Violin Concerto which is another extraordinary piece and probably the one that has inspired so many composers since to write large violin concertos.
