Please, watch the video even with no sounds. There are all the answers to your questions.
I have just done so.
My two questions were: 1. In regards to the extensive training you described in your native Russia, is that not more complete than what you are proposing? Which is more satisfactory for those who are capable of learning the complete way. 2. Is a transition made toward a traditional horizontal staff?
I did not see an answer to either of these two questions in the demo. However the demo is for the purpose of learning the "time" aspect of note reading.
I should identify myself as a former teacher with training in learning disabilities (have I already?), which can involve alternate approaches, and using alternate senses to the usual sense of vision and hearing. Music is attractive in particular because it involves the use of the whole body, and the combination of touch and hearing, instead of necessarily vision and hearing, for those who are weak in the visual, or audio-visual area.
Ok, I played the demo and it was sort of fun. A first comment - is there a control of speed in the program? It looks like it is designed for a basic, older computer, which is good - but I have a very fast computer so those notes zipped by at a speed you wouldn't believe. They would not "zip by" on an older computer. That should be controllable.
It was very strong in creating note-value recognition. All the half notes went into the half note basket, and it creates a very strong recognition of half notes, etc., as separate entities. It sticks to the brain. Green apples are earned with one kind of note value, red apples are earned with another kind of note, so again, my mind is really impregnated by the character of those symbols. They become old friends.
I don't know whether I would end up associating timing with the notes. The half note travelled to the basket that was far away, and the eighth note travelled to a basket that was closer by, like different addresses, distances, not necessarily time. I'm trying to see it like a child or novice. Because I knew the purpose was timing, I counted the lines it went through, so I got a sense of "fourness" for the half note (four eighth notes). I don't know whether subliminaly I would have absorbed a sense of timing through the exercise.
From what I experienced, the different types of note values/symbols became clear, they lived at different addresses, and the empty note (half note) travelled a greater distance and had to cross more lines than the black note with the flag. I'm sure that there was a background sound giving a tempo beat, so it would also reinforce tempo through sound.
Not a bad tool for recognizing those notes and associating them with note values, though I imagine there are all kinds of games that could accomplish the same thing.
What bothered me is that it is totally visual, there is nothing tactile, no body use, no clapping, stomping, marching, tapping, swaying. It would have to be part of a larger picture, and not the whole picture, wouldn't it?
