Well that dictaphone version can be safely discarded - the sound is just too bad to tolerate. I did not manage more than 5 seconds of it.
But the 29 aug version is not bad. Is it a real harpsichord or a digital keyboard ? It is still rather slow but acceptably slow, not comatose like your first submission. This time I listened to all of it and did not get bored
What I find bad here is that you pull the rhythm and tempo badly out of shape whenever there is ornamentation. You can be a bit free with the ornaments but not by as much as you do here. This piece may be slow but it is essentially very rhythmic. You need to make sure to 'keep the groove' as some would say here. Allow a litle time for the ornaments, if needed, but do not drastically change the pulse. Apart from that, it is solidly played, though some of your ornaments sound a bit unfamiliar. Sorry to go on about them, but they are so
important in this great little aria.
