Hi Bert, thank you for making your postings - I enjoyed listening to them. I like what you have done with the improvisation of the folias.
As for the Ghiribizzo, the timing is fairly consistant and the pull offs sound pretty good - though the poor sound quality makes it difficult to tell in places possibly due to a low pass cut out. I do hope you don't mind if I pull you up on couple of errors though.
You will notice that there is a base note at the beginning of each bar (measure) and the base note linked to a trebble, this means it has the same duration as the trebble. In bar one this is a crotchet or quarter note, so the base note lasts for the first beat of the bar and should be damped for the rest of the bar. In bar 2 it is a quaver or eighth note.
So what I am saying is that there should be damping on the base notes throughout the piece. You seem to have missed this.
In part 2 of this piece the key signature changes and it loses all the sharps. You have been playing part 2 the same as part 1. So in bar(measure) 17,18 etc. the c sharp becomes a c natural. You are still playing the c sharp as in part 1.
As for audio quality, the zoom h1 is an excellent option and not too expensive £85 uk.
Good luck Bert and keep practicing - I hope to have my version up soon.
