Jupiter - glad to hear you're finding your way.
One tip though - that is to go ahead and post your Key Sound™ sample to the
Free Key Sound™ validation service.
By far the most common reason that people report not much progress with this method is that they are not articulating the Key Sound™ correctly.
The validation service is free. I can't make it much easier than that.
All the best in your continuing explorations, whatever paths you may choose,
Jack
