Do you struggle with sight-reading on the organ?
Can you only play slowly from the score or play faster from memory but not both?
It's frustrating, isn't it?
You sit down on the organ bench to sight-read a piece that you love but never played before and you discover your ability is inferior to what your fingers can do.
In other words, you can play faster, but not from the score.
So you decide to memorize.
But then all those instances when you forget the text, panic and freeze make playing without the score quite uncomfortable.
The real problem is not that you can't read music fast enough but that you don't recognize patterns which would facilitate reading the music.
And this comes from knowing music theory and harmony.
Here's what you can do:
Not only you take up sight reading challenge for the next 50 days but you also begin to study basic chords, their inversions and resolutions in various keys.
Then after 50 days you'll re-evaluate your sight-reading skills and I guarantee the results will surprise you for the better.
