This latest intervention expresses -Gilda, forgive me if I say this brutally- exactly the cliché that I intended to refute with my article. How can one confuse a completely passive quality of the human body (hair, broad shoulders, green eyes, etc.) with a quality that develops through knowledge and that intertwines with creative ability?
Ease of intonation is certainly a basic talent; some are more gifted than others. But I challenge a person who is extremely in tune but lacks self-discipline and logical capacity to play the piano and face Bach's polyphony: in that case, intonation is useless, method counts much more, along with a logical/mathematical mind. I reiterate that music is a discipline that draws from an innumerable series of talents, not just one, and that even people less gifted in one or more of these talents can and have known how to excel in music.
Some examples for the skeptics, across various musical genres. Chet Baker, Antonio Jobim, Lucio Battisti had approximate intonation. Thelonious Monk had a very modest technique. It is read that Chopin's own performances of his music were anything but impeccable. Frank Sinatra had a very limited vocal range. John Coltrane managed to overcome heavy limitations thanks to total dedication; those who know him recount the difficulty of his progress.
I know some musicians gifted with perfect pitch (a physical quality of the person) for whom this talent has, in the long run, become more of a burden than an advantage. In fact, they have skipped entire important phases of exploration and deepening, becoming approximate musicians and much worse than many others who are less gifted.
I believe I have expressed my thoughts in a manner that was perhaps even too vehement; very cordial greetings
