It's one of life's paradoxes - on a par with dark matter, black holes, neutrinos, and the behaviour of blobs (slime-molds) - that in our age, it's never been so easy to get hold of free music (five centuries' worth of it, from IMSLP and elsewhere) for recreational sight-reading, yet at the same time, fewer and fewer students are doing it.
Probably because evolution by natural selection has selected humans who know how to get the most bang for their buck, i.e. getting the quickest instant gratification for the least expenditure of mental and physical energy. We see the consequences of that every day. (Hmmm, I'm sure someone has written a treatise on this, otherwise I might write one myself......but then, I'd be expending a lot of mental & physical energy for long-delayed gratification, or possibly none at all
How does one become fluent in a foreign language? The quickest and most efficient way is by immersing oneself in it 24/7, hence all those language schools in the countries that use the language. One is forced to speak, read and write that language 24/7, for everything from food to foot(ball). It's amazing how quickly one becomes fluent.
Failing that, use that language at every opportunity. I started learning the Western alphabet at nine (- my first three languages don't use anything resembling the alphabet), and when I discovered the treasure trove of all those children's books (Enid Blyton), adventure books (Willard Price, Cpt. W.E.Johns etc) and detective novels (Agatha Christie etc) in the library - most of them in English - I couldn't stop reading. For months, I was reading one book a day (more at weekends), with a dictionary by my side - reading till I fell asleep most nights. Which was why, when I moved to a boarding school in the West a few years later, I was able to read complex high-brow literature like Lady Chatterley's Lover
without needing a dictionary, as well as communicate with everyone in English. I was already dreaming, as well as thinking, in English by then. Such is the power of recreational reading. Reading for fun, not as a chore or "duty".
That was exactly what I did with music too (when I moved to that new high school and had unlimited access to its music library), which was why I was soon able to sight-read piano music that was actually technically too difficult for me to be able to play properly.
So - to everyone who enjoys exploring music (which hopefully is everyone in PW) - explore by sight-reading/reading it, not by clicking on 'play' or asking Ms Alexa (whoever she is). Within a few short years, you'll be able to sight-read anything at the drop of a hat (if anyone wears a hat these days)........
