It is about note perfect (musically, is another issue). Some unsteady moments in the trill, I think I half slipped some place but otherwise I think I got it down right this time.
Slips there were maybe none, but I believe some reading mistakes (could also be score deviations, mine is Henle Urtext):
Bar 1 : 3rd beat: Sounds like you omit the second RH b
Bar 6 : The 4th RH note should be d, not f#
Bar 12: 2nd beat lh is d - e no e-d
Bar 16: 4th beat, d# should be d
Bar 1: Put headphones on, turn up the volume and you will hear it. Too low, yes but it is there
Bar 6: Correct...&¤#(/
Bar 12: My score (see picture) says lh e-d but I check with an urtext which also says d-e.
Bar 16: Again see picture of my score. Says D# but again, the urtext says something else. I blame Czerny (I use his scores).
Also, check the manuscript which does not make sense really to any score I have seen. Can someone explain?
The long trills are the Achilles heel indeed. The first one is a bit wonky and sounds as if you end it on the upper note. The 2nd is better, but are you sure it would not sound better using c# instead of c as upper note ?
Tried that but I did not like it. Perhaps cause I'm not used to it. Will try again.
The Impromptu is getting nicely into swing ! The outer movements are really pretty good, but I suspect you have neglected the slow middle section a bit, most slips and read errors are there.
When the reprise starts, it sounds a bit timid compared to the beginning, not really "a tempo". But that could be a choice you made. The smorzando on the last page sounde more like a stretto to me.
Apart from that, a good recording and technically good playing.
It is much true that I have a bit neglected the middle part but comparing to how much I normally spend on a piece, I feel I have really put in some effort here and had some great help from my teacher. I played it for him this evening and he did not really point out any reading errors. I should use this as a warm-up exercise to correct problem in my technique so later, I might perhaps record it again.
The Burgmuller, hehehe... I really never heard that piece, and can't see why it would be popular. Amazing you play this from memory after so many years ! A bit like my sister who remembers every tune she's ever played in the distant past even if she doesn't know what it is.
I seem to easy remember some pieces while have really problems with for instance Bach. Or rather, have memorise problems when it comes to counterpoint. This one is really easy, in A-minor and follows the rule of a melodic minor scale. My teacher as a child used it at me as an exercise to establish equal speed in both hands so I have probably played it 1000 times or so
