There are different ways to be bad at sight reading. For me, I had no problem with notation or rhythm, even in the most remote keys, but I was lousy at the "touch typing" aspect of sight reading, knowing where the keys are without looking. To fix that, I started 30 minutes a day of reading things so simple that I could find the notes without looking, for example, the first exercises in here...https://imslp.org/wiki/Sight_Reading_Exercises%2C_Op.45_(Sartorio%2C_Arnoldo)When that got easy enough I switched to things like Music For Millions in the beginner level, they have a couple of volumes of easy things. I try to play those without looking at the keys and at a tempo slow enough that I do not need to stop. Eventually I moved on to harder things and went through bunches of Scarlatti sonatas, then all the Mozart and Haydn Sonatas, Bach Suites and Partitas, etc. For the harder things, I play lowly enough that I do not need to stop, but I do let myself look at my ends for bigger jumps and that sort of thing. It's fun. It just takes time to improve. You might improve faster if you did it for an hour a day, but if you are working up to college auditions you may have other ways you need to spend your practice time.
Strange the link in IMSLP says "Sight Reading Exercises, Op.45 (Sartorio, Arnoldo)", but when you open the file, it says they are by G. Schafer. I opened both vol II and vol III.I think I could start with vol III. I suppose I "should" get better at sight reading, but not really sure I need to, since I mostly work on challenging pieces that take months to master, and I try to get to performance level.
Okay hear me out, I can play with decent dexterity but I CANNOT SIGHT READ FOR THE LIFE OF ME. Like even the most basic of all basics, like it'll take ages for me to read which sucks and college auditions are fast approaching and sight reading is apparently a requirement, so how do I manage to do that? I know it sounds kind of impossible, but is there a way to make it possible? help please
