Hi Bert, I also enjoyed listening to your playing.
I would like to make a few comments on each piece if a may:
Arpeggi di 4 note
Timing is good, you play evenly throughout.
Buzzing in base - When you play the lower base there appears to be some buzzing, this can often be caused by stiking the string up and away from the guitar rather than in the plane of the sound board
String dampings - Measure 13 and 15 have string dampings as shown by the pin wheels. I think you have missed these
Measure 16 rest - There is a sqiggly line at the end of bar 16 which indicates a rest for the last beat.
In other words the last beat of the final bar(measure) should be totally silent.
Arpeggi de 3 note
Timing is nice and even again, buzzing still in the base notes.
String damping in bar 6
The rest at the end of bar 8
No buzzings in the base here - the rest strokes are making you play the string paralell to the sound board.
Your bases and trebbles are coming together very well, your timing is good and you are playing all the right notes.
Are you missing the string dampings in this one? It is a little difficult to tell from your recordings. Also, your
timing is not even throughout, you seem to be slowing down for the difficult bits like in bar 11, the boxed section
which we are supposed to practice 5-10 time each day before attempting the whole piece.
You need to either slow the whole piece down to keep an even tempo, or work on the difficult bits.
Other than that, well played and keep up the good work.
