Learsfoot, you are right on the mark here and I wouldn't try refuting anything which you've just said. Keep in mind as well while concerning performance practice that Vienna was the mecca for music because composers, conductors, musicians, etc.... were in constant contact with one another and together they invented what is now the Viennese School. The point here is that more performance practice has been handed down by word of mouth than usually realized. Hence study with a great conductor, then use that lens of perspective when pulling briefs off of the library shelves.
With the invention of electronic communications, these sources of information travelled further and faster so that Bartok was able to record Hungarian folk melodies which in a way negates the need for him to notate anything. The practice of improvisation varied greatly in the jazz world and very little of it was written in a formal sense. So you bring up several good points but the one that speaks to me the most (besides Hindemith) is that many conductors from the golden era tended to follow in lock step with one another regarding tempo. I really find this to be unquestionable however as we take a distance from what was going on then, it's clear to acknowledge the overall impact that both recordings and film had on the practices of the time and I wouldn't hesitate to assume that the record companies had as much of an influence on the outcomes as did the artists themselves. I'm not suggesting that conductors were being compromised but if Mahler suggested to Walter to shave off two minutes from a scherzo to achieve a particular quality and it became effective, then consumers of that recording began to set trends. Lastly, composers, conductors and musicians are influenced by popular recordings just as any other fan would be. Would you not say that this point of view would then explain some of the mentioned commonalities and conformities of the past?
