The best answer is to get at least some months of live classes with a local teacher.
He can teach you the basics and correct bad early habits in a way no distance learning method can.
She will also be able to keep you motivated during the initial step learning curve.
After you get the basics you can complement it with an app.
For that you would need a digital piano that can connect to a computer or tablet with an usb cable, or Bluetooth.
Accoustic pianos also work, but the app will be capturing the sound and not receiving MIDI electrical inputs, which is more error prone and can offer a worse experience when playing multiple notes together.
The best app is called Piano Marvel, but you can easily google other options too.
Unfortunately no. I have some course notes that I was putting together during the last iteration of the course, but they are in no way ready for public release. And while many other introductions draw a connection between classical and quantum, I haven't seen any that follow the same radical development as mine.
Scott Aaronson does follow a similar line of thinking in this Quantum Computing Since Democritus lectures [1]. He talks about the p-norm aspect, but doesn't talk about the tensor product structure. And I think for good reason. The way I teach is good for learning, but it is not how you would ultimately think about the link between classical and quantum computing, once you become an expert. Then you should think in terms of complexity theory or in terms of axiomatic relations between classical and quantum theories or information theory principles etc.
There is also David Mermin's book, which has a section on a similar sort of reasoning. I don't recommend it as a self-learning book because it has no exercises.
An example of a textbook which starts from the discrete, linear-algebra form of QM (using the Stern-Gerlach spin experiment) is "Quantum Mechanics: A Paradigms Approach" by David McIntyre of Oregon State University. It's not quite like what's described here, but much closer to it than the more traditional way of teaching QM (using differential equations).
