I have not contributed to this discussion, as I need some time to work out technical issues on my own. However, the discussion is exciting and I feel very much part of it, even though I do not know right now how I can make best use of the community. I expect that to change, once I start playing music.

I find that I do not know enough to solve the problems I am having. I am therefore going back and learning microtechnique consistently. This learning is giving me a lot of things to look at when something goes wrong, and a much larger palette for solving problems. And the direction that this going in, is that there are actually only a small number of microtechniques that I need to watch very carefully: - make sure you always have a finger that guides you to the next note or chord (it is called "eje"= pivot in Spanish). If moving to a new position, look for the finger that can stay on its string. If moving vertically, look for a pivot finger that stays on the same string to get another finger to the new string. - Think about how to let wrist rotation do much of the work of moving across strings. - Anchor the right hand on the 5th (or whatever convenient bass) string. I am sure I will add things as I continue learning. I am happy to have input. I am only playing exercises now. I play an occasional piece of music as a reality check. I clearly see improvement, but I also see that not all the things I have learned are automatic yet. And under time pressure, I fail to apply what I know. @Marc Adler had already predicted that applying knowledge of microtechnique to actual playing would take effort and definitely not be automatic. He is right.

Just discovered that I am also lifting fingers too early, thereby ruining the legato continuity of the line and the guide fingers that I need later. @David Norton had told me that I do this, but I am only now realizing it. I am still working on technique.

@Blaise Laflamme Yes, of course. The flat packs solve the problem that I have huge quantities of music in ring binders with each page (two pages, front and back) in a separate plastic document holder. Those ring binders take up some 3.5 meters of shelf space. In flat packs, they would take up less than 50 cm. I prefer to play from ring binders. But I do not need 500 pages of JK Mertz or the complete solo guitar output of AJ Weidt in a ring binder. However, I do not have time right now start making flat packs out of everything. By the way, once you have a square stack of paper, making the flat pack takes about 15 seconds (it is called fan binding). Then you put it under a brick and let the glue dry for about 4 hours.

@Blaise Laflamme True. But it is important to see the full works of Mertz from time to time, to see what is there. For instance, a person might miss Opus 2 or Opus 4 or Opus 5.

@Malcolm Lane I just did exactly that. I connected my wife's office (upstairs and 25 meters away) with an Ethernet cable to the router in my office. I took the Ethernet cable through the hole in the outside wall where the air conditioner pipes go out to the air conditioner (in Israel, all air conditioners are outside; I have never seen such an air conditioner anywhere else, but I am sure you can either use an existing hole in the outer wall or make a new one — very small, just big enough for the plug of the Ethernet cable). Then I took the Ethernet cable all the way around the house and up one floor to her office and went in through the window. As soon as my contractor returns, I will make a small hole for the Ethernet cable so that we will not have to go through the window. The Ethernet cable must be protected from the sun by covering it with a conduit for outside use. I guess that in England you have less problems with sunlight than we do here, but the Ethernet Class 6 cable is definitely not suitable for outside use. The entire project cost me less than 400 euros. Not cheap, but peace in the home is worth 400 Euros.

@Malcolm Lane Does the person you are addressing know that this is directed to them?

@Blaise Laflamme Sound, touch, and feel are not perfect after a year, even with Aquila strings. I am looking for the hour-and-a-half to change strings on three guitars.

@Blaise Laflamme Yes, very smart. But that requires scheduling 3 string changing sessions. How did you know that it takes 20 minutes? I did an extended statistical study with 4 guitars and using the MusicNomad manual string roller (it is very fast). It takes 6 minutes to unwind and remove all 6 strings and 14 minutes to put on the new strings and bring them up to approximate pitch. String cutting is not allowed in this test.
