The Noseda M10 has excellent program notes by David Matthews - the best I've read on the Cooke version. As most of you probably know, Cooke's 2nd and 3rd versions contain some contributions - changes in orchestration, minor pastiche composing - from the Matthews brothers; David and Colin. David Matthews acknowledges, perhaps for the first time by anybody, that Goldschmidt did much of the orchestration for Deryck Cooke. This makes sense, but Goldschmidt often times voices his woodwinds the opposite of what Mahler often times did himself. Namely, Mahler frequently exploited the upper range of the clarinets, while voicing the oboes in their middle and lower range. Goldschmidt frequently does the opposite: high oboes, low clarinets. This leads to a somewhat uncharacteristic sound, especially in the first scherzo, which D. Matthews acknowledges as being "the basket case" (my description, not his) of the five movements.
Correctly - in my belief - Matthews states that Mahler undoubtedly would have greatly revised the first scherzo. This is where I have a problem with many of the other completions: those folks took a lot of time and trouble to rework the second scherzo - which really doesn't need much help, just as it stands - but basically excepted the first scherzo as is. More importantly, D. Matthews discusses and defends the contributions that he and has brother made to the Cooke score.
Matthews explains that he - and his brother - would meet with Cooke for hours, even over the smallest adjustments to the score. In other words, nothing was done hastily, or without Cooke's serious consideration. Thank goodness for that! But here's precisely where I have a difference of opinion with Matthews.
Matthews states that he talked Cooke into expanding the orchestra from triple woodwinds and brass (3 of each), to quadruple woodwinds and brass (4 of each). Using "DLvdE" as a model, he confesses that he - and his brother - convinced Cooke to reduce the tuba part in places, and replace it with the 4th trombone instead. The idea was, more or less, to make the tuba solo that opens the fifth movement, more of a surprise. But this is very falacious thinking on their part. In all of the symphonies where Mahler employs a fourth trombone, the tuba is kept very busy indeed. In the sixth symphony - the most low brass heavy of them all - Mahler doesn't even use the fourth trombone until the finale. In the third symphony, Mahler's useage of a fourth trombone is mainly to allow him to put two players on a part (where he divides them into two-part harmony). The entire brass chorale in the sixth movement of M3, for example, has the trombones split into two-part harmony. This explains why many of the louder and more climactic moments in the two scherzos of M10 don't have more tuba on the bottom (often times, none). In my mind, this is a fairly major mistake in a Mahler symphony that is going to have four trombones and four trumpets employed (and ideally, the horns should be expanded from four to six - just like in the fifth symphony).
Well, getting back to the first scherzo, in addition to six horns, it's my belief that the movement cries out for two sets of timpani with almost an entire scale of notes available to the players at any given time (hence, cutting down on retuning). Obviously, that means that I would greatly expand their contribution, but not with double rolls (which aren't not necessary). That's not to mention the complete revision of the first scherzo that D. Matthews admits is necessary (and of course, the Cooke camp argues that only Mahler himself could have made those revisions). I'm not advocating that somebody should do a major revision of the first scherzo - a recomposing job - but I do believe that it badly needs to be reorchestrated in its current state. Your thoughts?
