Thank you, Alan, that is very kind.
The guitar has a very nice, warm sound, but it is hard for me (a beginner) to produce a sound sample that shows that nicely.
I realized from some of your other posts that you started playing relatively recently. However, I think you must be getting very good guidance. Your performance of the piece avoided some of the common earmarks of beginners, especially in the phrasing, and it was a pleasure to listen to it. Those pieces are called "simple" in the title, but the piece you played is not real easy to play, especially for a beginner.
I think the term "simple" probably applies much more to Brouwer's aesthetic approach in putting together music with elegance than it is an indication of the level of expertise required to perform it. That's speculation on my part, as I don't know that for a fact. But it is the impression I get in his etudes.
In my opinion, that piece is definitely an intermediate-level in difficulty of execution. Fingering the chords so as you don't muffle the strings requires some effort to master, and transitioning between the chords can be challenging.
Too many people play that piece too fast in my estimation. It is better to play it at the tempo you use, in my opinion. To my ear, it seems more beautiful that way than when rushed through. It's kind of a tranquil, meditative piece.
The recording equipment that you used probably does not do the instrument justice, but I could hear it well enough to understand that it is a very nice instrument indeed. No doubt, your tone will improve, but I think that you have reason to have pride in what you can do right now.
As I said, it's obvious you've been getting some decent coaching.
Regards y saludos
