That´s why the sax is an exeptional instrument, there is almost no right thing and wrong thing, almost nothing like "that´s the way it must be".
The Rascherian sub-culture is (at least partially) a reaction against that lack of "standards" (qualities valued in classical music and used as measures of excellence).
What if anything this has to do with the neck issue, I won't speculate. Part of classical "standards" is backing up subjective judgments with the force of authority (ie: "every clarinetist must play an R-13").
The "why" of it is, in a way, unimportant. Give credit to Rascher's people here - he was hyperrational and always had reasons for doing things. (Closed C#
is mellower in tone. F2
is a more reliable tuning note on any sax. Overtones are good for your playing in ways we can't, or needn't, even explain.)
The various neck fetishes are an exception. Here hearsay and mumbo-jumbo rule. That to me says a second generation has come into its own, people who didn't know the master personally. (Neither did I, FWIW.)
I guarantee you one thing, though. When Buescher sent out altos with different necks, they were
not thinking of classical music. I'll bet anything it was an experiment to improve tunability with the new variety of mouthpiece designs that started coming in in the 1930s. Ie: a commercial, real-world, marketplace solution.
(FWIW, I tune best on the ** neck. But I'm a biter, non-obsessive overtoner, and play too much unserious music. So... :? )
