PianoMonk To me, learning to play a musical instrument isn't rocket science, or even neuroscience.
I don't disagree with a lot of what you're saying, PianoMonk, except for this part right here.
Learning to play a musical instrument is a cognitive activity, and as such, how we approach that learning can be improved by understanding how the brain works. This is what neuroscience is all about, a systematic approach to understanding how the brain works.
I am not a neuroscientist, but in my day job, I'm a linguist -- I do linguistic research and in addition to teaching courses in my main area, I also teach a foreign language at the university level. I know, from my own research, from extensively reading in the field, and from first-hand experience in the classroom, that what teachers do in classrooms and what students do on their own, while studying, impacts their progress, their accuracy, and their ultimate learning outcomes.
Whether or not any individual piano student wants to apply practice techniques advocated for by Gebrian, or any other teacher, is up to them. And certainly we can have a discussion about whose approaches are better, whether they're implementable, practical, sustainable, appropriate for an adult learner etc.
But learning to play an instrument, like learning a foreign language etc., involves the brain and as such, neuroscience is without a doubt relevant. Highly relevant.
PianoMonk I'm skeptical of "new" approaches to methods that have worked for so many in the past, especially with something like music.
As to this comment, I think the point is that, in fact, traditional ways of practicing (and teaching) have not worked for a lot of piano learners, especially adult learners, or have not worked well enough. I've been on these piano forums for over 20 years now (yikes) and trying to figure out more efficient and effective ways to practice is a perennial topic exactly because people are wanting to make their practice time more effective and wanting to see more success from what they're doing, from the time they're putting in.
Given that, the constant searching for new methods, a healthy amount of skepticism is justified (your reference to the Atkins diet is a good one, there are always people trying to sell their method as the "be all, end all" answer to everyone's prayers).
But to say that neuroscience isn't relevant, or that it's not relevant because previous pianists and composers didn't have access to the science we are now learning about, seems actually defeatist to me. And to not take advantage of new understandings of how the brain works seems like a missed opportunity.
