All I know is the Great American Standards , and great they are, would not
be what they are without lyrics . My favorite, " Autumn Leaves" is largely what it is because it was written by a Frenchman .
Spanish is a great and beautiful language, a strong second to that almost universally considered the most beautiful, French. A bias would be if you did not feel your native tongue the most lovely .
German is, objectively , considered a harsh and guttural language and so it is .To me, because of the Schubert lieder and my love for the country in general, it sounds’ more better" than English . That’s a bias .but not too much as they were the same language once and English is harsh as well.
To my hears the French is more beautiful than the Spanish and I know little of either .
My bias is to sing to "Concierto en Aranjiuez " is little short of criminal .
I think it is a true and wonderful Masterpiece for the guitar . I must of heard it a thousand times and every time is like the first . Amazing .
