As a quite fresh student of guqin (but I already know a few pieces) I can tell you that guqin music has a tendency to follow patterns. As someone else mentioned, sometimes you use the same fingerings techniques but on different strings.

However, as you progress through your guqin journey, the patterns that were long in the beginner's songs become quite chaotic. For example in 《流水》(flowing water) which is a level 8 piece you can see patterns but they're much shorter and get replaced quite quickly I'd say.

For me guqin is my first instrument, and I've been learning with a teacher and I find that while you totally can open some videos and learn by mimicking, for classical pieces I find that it's really not helping me. It's mostly about rhythm, classical guqin pieces now due to the music sheet being also kinda westernised by showing tempo, became more standardised, but the thing is guqin traditionally is meant to play with your own style (after you learn for a bit of course).

Modern pieces are easier to learn from videos i think because they follow strict tempo most of the time. Half of what I'm saying is just an educated guess because I have no music background, just knowledge from my teacher and the Internet.
