I downloaded all pieces from Beginner Level 2+3 from this site:
Big thanks to ranjit for the link!๐คฉ๐
Then I added each collection into a single pdf-anthology with index and page numbers. The first two have about 130 pages. This is way more material than the books I bought at Amazon. I also changed the order of the pieces here and there to avoid page turns of longer pieces. (Odd = left page, Even = right page)
If everything is done, it will be 8 books in total: Beginner 2+3+4+Classics and Intermediate 1+2+3+4
For now, this is by far the most fun resource to practice sight-reading. But I must admit the "Improve Your Sight-reading" by Paul Harris books are still very useful because they follow a didactic method. Introducing more complex keys, then enhancing the rythm and whatdoIknowwhatcomesnext. The problem with Paul Harris is to have not enough stuff to play before he ramps up the difficulty. And his "One piece a week" series sucks so far. Those pieces are no fun at all, maybe they follow a didactic scheme.
If someone is interested in the pdf (~130 pages, >20 MB), please write a PM.
