Beethoven: Piano Concerto No. 4 in G Major, Op. 58: III. Rondo (Vivace)

orchestra is less to my liking in this movement in this recording - not quite light enough.

quiet c major opening, but nevertheless full of energy: this is the G major theme for the last movement. it features the rhythm quarter (eighth rest) sixteenth-sixteenth | quarter, and opens in C major for a while before correcting to the G major tonic.

1:12 - B section, in a lovely pastoral D major. features lots of great arpeggios and acrobatic playing.
2:27 - the piano leads us with some scales right back into the A theme.
3:13 - piano takes the bombastic part of the A theme in a completely different direction, ending in E-flat major. (later B-flat minor, F minor, etc etc) one can think of this section as a sort of development.
4:37 - the development leads to material from the B section, this time in G major.
5:51 - we start diverging from the original B section material. eventually we get to a big F-sharp diminished 7, acting as a vii to G.
6:28 - the G acts as a dominant to C, putting us back at the A theme.

the last part of this movement is quite unique: starting at 7:00 we have a normal F#dim chord, which switches enharmonically and becomes a Gb Major chord, putting us more or less as far away from the tonic as we can get. now we're on a sequence around the circle of fifths, leaving us in the perfect position for cadenza.

9:28 after the cadenza we spring into a super fast coda, led into by strings with D-A alternating eighths. from there on it's a straight shot to the end!

very fun concerto.
