Carlos, J.P.'s flutes are pretty similar in reach, until you get into D# or D. Then the bore size increases enough to affect the finger reach. Otherwise, the fingering is pretty similar on the Sedona, Courting, and Special Concert series, although the Special Concert series is a little nicer flute overall, and it may have a tad easier reach for fingering, but nothing significant.
You can get a greater finger spread on flutes in the higher range, as J.P. often uses a much longer sac on such flutes, to allow for easier fingering, without crowding the holes.
The same holds true for some other makers, that use longer sacs in the high range.
Typically, though, the larger the bore size, the easier the fingering, in mid range. There is, as I understand it, an optimal bore size to key ratio, however, so makers tend to stay within a narrow range of bore size for a particular key.
Rick and all,
I just realized what Rick meant by "sac." Took me a minute. Slow Air Chamber and yes, you've added yet another factor -- that the size of the slow air chamber can make the flute longer (i.e. the holes farther away from your face) which could also affect hand positioning as it would be further down. So still, a lot has to do with the flute construction.
I will have to compare my JP Sedona G to my JP Concert F# and check out where the holes are. I have a Courting model but that is mid-high B flat (A#), a real sweet flute in old growth redwood. But some of you folks definitely have me beat in the flute ownership department, although I'm close to (or at) 30 flutes, mostly NAFs.
I do know that one of my first flutes was a High Spirits F# that I no longer play, and the finger reach is fine for me now, but at the time I was surprised to get an E from another maker that was an easier reach. I was told by High Spirits that was because the bore was wider on my E, and that was one of my first "aha" moments on this whole issue.
You added yet another factor to the mix -- that the way the hole spacing is done can also assist in ease of fingering.
I've heard it said by several sources that it's good to start with an A or G flute, or something mid-range. Generally speaking, it seems to me that the reach is easier, and the breath control skills are easier to establish in that range. I know that in my flute circle, and in Mary Youngblood's workshops (and other workshops as well), folks are encouraged to come with an "A" flute if they have one. So many folks have As and Gs in Loping Wolf that it makes it easier to play together.
It takes more air and technique to play the lower flutes, and with the high high flutes, seems like it's a compression/pressure thing. I used to play oboe years ago, and part of the idea was to build up pressure -- it's just a small double reed and only a certain amount of air was supposed to be going through it. I used to exhale before inhaling again.
But then once you have a few mids -- it's like, "What can I try next???!!!" The flute adventure is never ending ...
peace and harmony,
Francesca
