Youâre in for a wonderful experience if you do end up buying a NAF.
To start with, yes, they always have those âstrange dangly thingsâ. Itâs part of how it works. There are two separated âchambersâ in the Native American flute. The first one opens toward your mouth and itâs the part you blow into when you play it. The second one opens away from you as you play it and generates the tones. Basically, you fill the first chamber with pressure from blowing into it. The air escapes through a small hole in the roof of the chamber, but thereâs a tunnel that directs it along the top of the flute and across a second hole with a blade, which leads to the second chamber. The vibration of the air as it passes over that blade is what causes the sound, whcih goes through the second chamber and can be controlled by covering and uncovering holes. Thatâs the really simplified explanation anyway. The dangly thing, if I understand you correctly, is either the fetish, which goes by other names and creates the tunnel between the two chambers, or the lace that ties it on.
Another possibility for the dangly bit is a cover for the fourth hole (from the bottom). This goes into styles of NAFs. The NAF is almost always in a five note scale (pentatonic). The octave note (not sure the proper name for it) is played by having all holes uncovered, rather than overblowing the bell note like most other simple woodwinds. Because of this, the complete scale, through one full octave, takes five holes. Youâll find a number of five-holed NAFs out there because of this. However, many (most?) actually have six holes and can be played as a regular five holed flute or the extra hole can be used to hit some different notes. Among these six holed flutes some come with a cover for the extra hole (the fourth one) so that it behaves like a five holed flute even without the player having to cover that hole. This cover is generally a piece of leather that is tied over the hole with excess simply dangling down.
A last possibility is purely decorational. Some people like their NAFs to have feathers or other things hanging off the bell end (or the middle, or anywhere) just for the way it looks. That is entirely unnecessary for the tone and is purely a matter of personal taste.
Now, for what to look for. As I mentioned before, there are five and six holed varieties. If you think you would have trouble getting used to the idea of always keeping one finger down, you might want to go for a five holed flute. Generally, however, I would say it doesnât make much difference. I happen to prefer the six holed variety.
Other things to look for include the key. Like many other similar instruments, the NAF is stuck in the key itâs made in. Unlike many other similar instruments, itâs usually a solo instrument, sometimes played along with a drum. For playing alone, the key isnât terribly important. F# is generally considered to be the most authentic key, if that matters to you. I happen to like the lower keys for the beautiful haunting sound you get. Before you buy one you might think about what made you want to play the NAF and go for a key that will be in the range of whatever inspired you. There are many makers of NAFs out there and prices range from around $50 to many hundreds of dollars depending on what itâs made of, how much hand crafting went into it, and what decorations it has. I would suggest starting with a somewhat basic one. You can find quite a few that will sound good for less than $100. Generally, avoid bamboo.
The NAF is an instrument that carries a lot of personal feeling in it, so the choice of which one to buy is a very personal thing. I hope I gave you enough information to be useful without swaying you too much in any direction. And above all I hope you find one you love and make some beautiful music with it.
