I think you would be interested to know how archaic our way of teaching how to read books here:
I am not too interested in the archaic style of teaching. Sight reading completely in 9 minutes seems a little fast to me even if this lesson is meant for total beginners. You said we can only see one line at a time, this is not correct , I did a speed reading course from Howard Berg, the words fastest reader, and he taught us how to read paragraphs at a time, and how to miss out useless information. This has great application to music, how to reduce the amount you actually read. You can actually teach to see more lines simultaneously, reading intervals between notes, not the notes themselves and this should be taught pretty much asap. We aim to reduce the amount the student has to read instead of inefficiently reading every single bit of information.
I do not like the strong link between reading words to reading notes in the youtube presentation. They are not that strongly correlated, there is no muscular memory associated with reading words in a book, unless you consider your eye movements and hand turning the page essential to reading words

. Many teachers teach reading separate from the physical playing which I think is not the best. It is important to get a student to know what group of notes written on a page can be played without moving the hand. This sets us up for reading our music intelligently, being able to identify movement groups (groups of notes which can be played without moving the hand and movement to the next groups) which will aid our muscular memory and thus aid our sight reading.
I also do not like the idea of naming notes on the keyboard with the actual letters. This might be ok for the person who has never touched a piano in their life before, but it should be removed and burnt to ashes. This security blanket restricts the students ability to memorise the names of the notes immediately. When I talk to a student if I say put this finger on C, I don't want them to look at the letter C written on a piece of paper telling them where to go, they have to know where C is by identifying the pattern that the black notes cause at the piano.
How do you help the student to read at a masters level. There are many different ways in which people can be taught how to read music but the application of knowledge is what is so important and what most teachers miss out (and try to do with one sweeping concept of teaching.) when developing the students reading skills. This is the archaic way of teaching and your you tube lessons are no different. Yes they can be effective, but they are not all encompassing and it will not make the student into a master reader, rather one who can identify notes but slowly. How do you increase their speed and accuracy of reading?
Certainly the very basics of reading can be taught in many fancy ways, but how do you develop from there? How can you get your student to sight read a Liszt Etude for example? Will you say, oh you will have to wait 20 years before you can do that? All I am saying is that your online lessons are nice, but they are suitable more for early beginner little children. I would question how your systems application to real music works to develop the student into a master reader.
I would love musicrebel4u to post a video of herself talking about pianostreet

Just to make sure that it really is her who is posting on here and posting on youtube.
