I'm an adult piano learner and just started to learn piano from a professional teacher. Previously I played a little bit electrical piano, which is totally different. I'm really bad at sight reading and keep making mistakes in class with the new piece, which makes my teacher really mad at me and stop me many times. I feel sad about it. Is it common? and what's the effective way to improve my sight reading?
When I was young, I could memorize any new piece for my next lesson, so I never learned how to properly sight read. When I was in music school, the very best accompanist in the U.S. could not teach me how to read.
So, at the age of 50, I made up my mind that I could do it, and I did. Mind you, I am not a great sight reader, but I improved well enough to read through 44 piano concertos in 5 years.
Therefore, you need to realize that the physical skill of basic sight reading is exactly the same as learning how to type. It is familiarity with the keyboard, so you can get around without looking down.
The first book you get is "You Can Sight Read Vol.I," by Lorina Havill who taught it at Juilliard for years. It has exercises where you play single notes, double notes, triads, and then seventh chords up and down the piano in octave sections. You start out as slow as you can in order to obtain accuracy. Even though it doesn't seem possible at first, if you practice this every day for just a few minutes, you eventually get to where you can feel your way around.
Next, there is a ten book series entitled "Four Star Sight Reading and Ear Tests, Daily Exercises For Piano Students," by Boris Berlin. These are very short paperback books that contain very short pieces at various levels of sight reading. They also have sight singing drills and rhythmic practice sections, which are essential to sight reading. I recommend that you get volumes 7-10. They are very inexpensive.
Set the metronome at the lowest possible setting, and then read for about 20 minutes a day, and no more. If you go more than that, it will turn into drudgery and you will hate it. A great idea is start every practice session by practicing your sight reading.
After you have read through to volume 10 at a slow and steady speed, then you go back to volume number seven, slightly increase the tempo, and then read through to volume 10. This is the text they have used at the Royal College of Music forever because it works!
In about a year or two, your sight reading will have improved by about 300%. A good basic yardstick is being able to sight read through Mozart or Haydn piano sonatas at a moderate tempo. From there, you can decide on whether you want to study accompanying and increase your ability accordingly.
So, practice the first book to develop your ability to get around the keyboard without looking down, and then the Four Star series to practice actual reading.
Good luck to you, and remember, if I could do it, anybody can do it.
