If I understand you right, you seem to believe what Bartok has defined so very precise, was simply wrong and to try to follow Bartoks advises is therefore wrong to.
Sorry that is simply not my attitude. I still believe the original composer deserve the respect, to try to realise what he demands.
In this case we are not talking about a few unclear general hints for the tempo. In this certain piece Bartok noted beside the traditional italian tempoadvises not only metronomic values and timesignatures. Not only once for a movement, but in all movements very detailed. (nearly always with italian advises, metronomic values and timesignature!)
If I understand you right, than to follow those detailed advises is in your opinion simply wrong. What means it obviously must have been wrong from Bartok to compose like that?
Sorry if you would be a bit more familiar with the concept of interpretation of Scores from the classical tradition, you would probably know, that there is always enough freedom for intepretation..... above the limits of what a composer spent the time to comunicate it with his score - but no freedom to simply ignore it. It is no crime to believe a composer in what he want. The problem seems to me more often that the interpreters simply are not courageous enough to beleive what the composer want.
The fact, that the by far most interpretations ignored what Bartok demands so considerably makes it in my humble opinion at least even more interesting, to simply try once how the music would be, if one respects the demands of the composer. It is a pitty, that this seem to you that inacceptable,while I can nbot see any concrete reason why exactly this seem to be worth to be as much reduced as you try it here. For the niveau of the discussion we arte trying to keep here. Just name me any concrete reason why Bartok was in your opinion wrong to demand the interpret to follow a that precisly defined a so detailed tempos and tempo changes.
Finally I would just humbly ask you, if you would be happy if anyone would comment the results of your work in the way, you do comment nearly everything I post here? Did you think the discussions here do have any benefit from the attempt to reduce the work of others like that? `....Just a guess.
I still believe those who realy work for and produce music and realise projects deserve at least the same respect one should always have for another, no matter how productive or not you in reality ever might be.
