There are many different methods for teaching sight reading. There are ways to teach a child to gradually get used to sight reading, there are ways to work with the piano, and bring the grand staff into the equation much later on, and there are ways to bring the grand staff directly into repertoire from the start.
I think that it is important to keep your standards high as a music educator. I do not believe that you should have unrealistic goals for your students, although, I think that it is very important to be aware of the capabilities of the human mind. All of my students are extremely unique in their own way, and also very intelligent individuals.
Out of all of the elements that are involved in learning how to play the piano, I think that sight reading is of the utmost importance. If a musician is able to sight read, they are able to adjust to any situation.
When starting with a young student; I like to bring the grand staff to their attention immediately. I feel that when I do this, it keeps the bar high and the student’s level of concentration right there with it. It is imperative that my students are well aware of how the grand staff correlates to the piano. If this is implemented straight away, I believe that it conditions the young mind to grow.
What are your thoughts about introducing sight reading to young students, and beginners?
