And about pattern reading/pattern playing. I tend to consider pattern "known" or "recognized" only when I can play it properly. But you pointing that out shows that different interpretations could lead to certain misunderstandings. I'll make sure to clarify this point.Ahh, that makes sense. When I look at patterns, the degree that I actually recognize it can be kinda determined by how many "sub-patterns" I can recognize and how automatic my respone to them is. What I mean by that is that on harder stuff with layered patterns, especially layered hold patterns, you can often be at a point where you more or less recognize what you have to play, but can't really figure out what the individual components that make up what you're seeing actually are. This also seems to be in line with the research I've done. It's effectively a process of "chunking". We've heard the whole "your brain can only handle 7 things at once" line, but it's actually true. The way we get around that is by "chunking" patterns into a "heirarchy" (each pattern can contain other smaller patterns, but can also be thought of as a whole object by itself). Just like we know that a car is made up of wheels, an engine, etc. and we know that wheels are round, and engines are made of metal, etc. you can consider the entire collection of notes visible on the screen as a singe pattern made up of various "sub-patterns", which are then made up of notes (or even other sub-patterns!). Often times I can read the individual notes, but not be able to really break something into "sub-patterns". When that happens I can still play it, but it takes more mental effort to read, which increases the chances of missing notes or playing poorly.
My understanding is that this process is naturally how we learn to be able to read these patterns, whether we're conscious of the process or not. The better you get at breaking what you see into patterns made up of "sub-patterns", as opposed to having to pay attention to each individual note one at a time, the less mental effort it takes to recognize the proper response.
Just to clarify, when I say "sub-pattern" I just mean shorter smaller patterns.
Here's a color coded image showing the 3 main "sub-patterns" I would identify in the pattern shown:
This is how I would actually think about that pattern when I play it.
You'll notice, however, that the right side is almost all red. That's because that section gets further broken down into separate nested "sub-patterns", which I learned to identify and play much earlier on, and are now have an entirely automatic response:
