Segovia made mistakes? - sure... everybody made mistakes in this or that
Majority will follow the same path as shown by "Great leader" in all kind of ways of life including guitar activities? - sure it was always like that and it will be like that.. we are just humans...
But, personally, learning a lot from all great guitarists, teachers and composers of the past, I never wanted to copy anybody! My main desire was always to be just myself and to follow my own path, with the great help of teachers from the past and present who gracefully shared all their technical and artistic ideas and achievements.
So anybody could listen my music on WWW and could like or dislike it,
but in the ways how I do it I do not follow anyone.
I play standing, not sitting.
I play 7 or 8 string guitar.
I play almost with no nails.
I am using all kind of techniques borrowed from different styles and different instruments.
I asked luthiers to build different original instruments to do different sound experiments and to get into different sound worlds and sound experiences.
For recording I believe (while technical stuff and devices etc. are very important) the most, critically important part is inspiration!!! Therefore studio work there one could have perfect audio environment and perfect sound engineers and producers without inspiration could produce not so great results...
I believe that most interesting and most important part of music life of modern musician is not endless repetition of pieces which everybody knows, but making of his own, original music which could express his own inner feelings and passions and nowadays one could complete his work himself as good as it was never possible before, because it is possible for anybody now to have a new great tools for audio work, and to be as free in mind as never before having at the same time opportunity to learn and get information as easy as never before in human history.
But absolute majority (and here too) will simply reject all this .
and will continue to repeat and copy as it always was and will be.
So what? - Everybody make choices. I made mine.
I should add here that I wrote all of this just to say that there are people and certainly in this field, who are not follow standard paths.
I'd better speak by music...Please listen my guitar at Spotify, Apple Music, Amazon, etc.
