to use the hackeyed phrase (and thus make it even more hackneyed): One man’s trash is another man’s treasure.
Nevertheless, each maker has, indeed, found themselves placed in the ‘heirarchy’ of makers worldwide. Sadly, that list is created by the beholder, catering more to a person’s desires and knowledge than all other things.
There’s nothing scientific about it.
what is seems you’re attempting to do is create is a way to decide, based on that information, which flute to purchase so that you dont’ have to go through the exhausting and unpleasant trial and error of buying/selling/buying/selling/buying, a never-ended process.
But you can’t. Unfortunately the best way to know a maker’s flutes is to spend time with them – certainly more time than the few moments you might have in a session with one, borrowed on the promise of doing it no harm by making a concerted effort at a strong/hard low D (why does everyone need to make that note?).
Terry McGee did it wisely years ago with the advent of his Embassador Flute (this I know because I had a heavy hand in getting him to do it and helped track its first few journeys with an online map…sort where in the world is Carmen Sandiego?). That gave people their first chance to try his flute…but sadly it was only his flute. It would be the same for the other makers had they tried it – and of course had a way to boost sales – and i’m sure it made some wonderous sales for McGee – but then you’d have to wait to try them all before ordering.
Some makers are best known for their Pratten-based designs (large bore, large holes, large sound, single-piece body) while others were better known for their Rudall/Rose efforts (although which Rudall that is can vary very widely…they should advertise which serial number they replicate).
Still other makers have their own take on classic designs (pat olwell is very much in this vein), and others can be extremely strict on replication of the originals (chris wilkes’ copies are so precise you’d have to look at the maker’s mark to be sure what you’re playing).
Some make very large embouchures which are incredibly accessible to the beginner (though can lead to a weak, unfocused “flabby tone”) while others make a very steep chumney that’s best left to the experienced player.
Others stay completely focused on which player is using which maker’s flute ("What is so-and-so playing?) Others prefer the makes of their local countrymen.
Some are more affected by waiting lists ("oh, i’ll buy one from the known makers as long as it’s not too long) and others prefer to toss as much money as is necessary to acquire an instrument rather than deal with a waiting list.
So, Grizzle…there is no real easy answer since each maker makes more than one flute style. You’lll just have to spend a lifetime like the rest of us testing them all out!
The best I can offer is to buy the best you can afford and which reflects your performance experience best. No need to drive a brand new Cadillac when you’re learning to drive; a Subaru witll do fine until you have the knack and don’t mind the attention. Then move up.
My first flute was a two-piece Ralph Sweet purple deal that cost me about $100 brand new, a lot of money for me at the time. Then a boxwood Monzani that I played for years and always with the intent of an honest-to-goodness Rudall & Rose.
