Karli, thanks so much for your replies.
You're quite welcome

I find it interesting what you say about tasks. I just thinking of the pieces I have to practice as several sections that I need to improve, and not as tasks that can be completed, so to speak.
Yes, I find that it's important and extremely helpful to think in terms of tasks or so. At the least, it's more efficient to think in terms of goals, and here is a place that I think is ever-evolving in a few ways :
1. Recognizing what the task/goal is/should be, and knowing when you have achieved it.
2. Having some sense of your personal ability to complete it satisfactorily for the day, including how much time it's going to take you to do it.
3. Knowing where that leads and how it fits into the big picture (of the piece, of the body of repertoire in general, you name it).
Your ability to do all of those things is (hopefully) going to be improving the more you do them. So, in a sense, learning a piece becomes not as much a matter of being "talented" in some ethereal or mystical sense, but rather one's ability to recognize, focus in on, and do those things above. That is going to be different for everybody for a number of different reasons. I personally learned a lot about how I function in that area by putting myself on schedules, but when I first started, it was something like "okay, I have here such and such a piece and I have 20 mins to get something done. When breaking it down into smaller portions, how much can
I really get accomplished in 20 minutes ?", for example. I learned a lot about myself this way, but I am still learning for sure because I personally feel that, for a few reasons, what I am truly capable of is just beginning to find its way. My overall goal though is to pick up a piece of music and be capable of identifying nearly instantly, exactly what it will take for me to learn it ...
Teachers can be invaluable in helping the individual in all of those areas as I listed above.
But it’s not time sensitive. I could spend an hour doing this, or three hours. Of course, if I made it a goal to get through every section I was having trouble with, then that’d probably take a while. Should I do something like that?
Well, I think that what is more important than "time-sensitivity" is "task-sensitivity" in that you know when you have "completed" something for the day. In that sense, I have found that there is a lot of useful information here on the board to help in guiding that, but the key element for me has been to develop/learn a specific process of learning that I know will get me some kind of concrete results (something I can consistently rely on). However, I expect that to evolve, too.
For me personally to take a piece and know exactly how to break it down and to know exactly how long it's going to take me to complete the tasks and so on, if I am truly capable of that, it's not currently something I could even attempt to put into words. Right now it is all happening in some other consciousness for me because the whole thing is very deep. However, I think there is an overall simplicity to the process of learning a piece, as well as the actual making of music, too. And, I think it is helpful to have the leading thought when approaching a piece to be a sense of discoverng how the process can be dealt with more simply/efficiently ... without robbing from the integrity of the goal. There is seemingly a fine line between efficiently going about making music vs. cutting corners in the musical concept and process of learning. In short, you want to be sure that the musical goal is always in mind and that no matter how simple and efficient your process of learning may be, your goal is still being achieved. Teachers can also be invaluable in this area.
I felt like it wasn’t enough.
Well, how do you know it's not enough ? I would start with what you can get and see what you can do in that time. In that regard, what Michael says here is a good idea :
I think it is generally better to increase the quality of practice first.
(...)
I think you will find as many opinions as people on the hours necessary for practice, but that it is UNIVERSALLY agreed that quality trumps quantity. Have fun!
Best,
ML
In some sense, I think it
can be a good idea to have a time limit because it can force you to think more focusedly. That is not necessarily true for everybody and it's not necessarily true in all cases of one individual though. At some points the stricter time limits may be helpful towards the cause, and then at other points they may not be.
In any respect, I think the only thing that is more important than truly inhabiting the musical substance of the activities we do at the instrument, is to truly inhabit yourself and your quality of living. Those things are in a sense "one" no matter what, but they are not always in sync with each other. In some way we are always chisiling out, with each endeavor, who we are. But, similarly to how sculptor may think of a piece of stone, I believe there is already a shape or figure in there just waiting to be revealed. Of course, an individual piece of music is very similar.
