They say you can't have a website without one, so for fear of falling prey to the web police, here it is:

1. I have small hands/fingers. Can I play the low whistle?

                  This is probably the most commonly asked question I hear in regards to the low whistle. The answer is, That depends.  It depends on just how small your hands really are, how large of a space there is between the holes on the specific brand and/or key of whistle you are trying to play, and how large in diameter the holes of said whistle are. So the reason this is probably the most asked question is that there
really isn't one good, simple answer for it.
                   Lets take the Low D for example. It is true that most low D's require somewhat of a finger stretch to cover all the holes, especially in regards to the bottom three. But the distance between these three holes can vary considerably per maker. Indeed, the stretch on some low D's is so great that it requires the use of the "pipers grip" (see Technique section) to play, where as others are small enough to be played using your fingertips. This of course also depends on how small your hands really are, and specifically how long your fingers are. As if this wasn't enough, you also have to worry about how wide your fingers are as well, as the second hole from the bottom of all low whistles tends to be larger than the others. Depending on how the whistle is made, this hole can be quite large in circumference, causing people with thin fingers to have difficulty completely sealing said hole.  
                    So what can be done? In an ideal world, one would simply try different whistles until they found one that worked for them. However, this is an unlikely situation, as few people live near a store that actually sells low whistles, consequently, most sales are done via the internet or telephone mail order.  Some makers do have a short trial period built in to their return policy, but you will still likely be out the cost of shipping. The best route is to measure your hand, specifically the distance between the middle of your index finger and the tip of your ring finger with your fingers splayed as far as you can comfortably separate them. You can then compare this with the measurements from various low whistles. Most makers and even distributors are more than happy to measure their whistles for you, as they don't want them sent back either. (I will also endeavor to include hole distance measurements on each low whistle I review in the Instrument Reviews section on this site)
                    There are some who feel anyone can play a low whistle regardless of hand/finger size, and that one just needs to teach their hands to stretch. While there may be some truth to this, I would think that the process of doing so would be so frustrating, not to mention painful, that it would take away from the enjoyment of learning/playing the instrument.  All is not lost however. If your hands do not fit a low D, they may fit a higher pitch low whistle such as an F or a G, as the shorter a whistle gets, the smaller and closer together the holes get.

2. What is the best low whistle for a beginner?

This question generally follows on the heels of the first one, and, like the first question, has no easy answer.  People tend to fall into one of two different schools of thought when it comes to purchasing a "beginners" instrument. One is that it is best to buy the lowest priced instrument possible so that if things don't work out as it were, you will not have lost that much money. The second, and the side I tend to fall on myself, is to buy the best instrument you can afford (and maybe just a bit more than you can afford!). The old adage of "you get what you pay for" generally tends to hold true with musical instruments, including low whistles. A higher quality, well-made whistle is going to; a) Play easier. "Cheaper" whistles tend to have more idiosyncrasies, such as unusual air/breath requirements and breaking or warbling between octaves or on specific notes.  These issues can add unnescessary frustration on top of the usual vexation of just learning a new instrument. b) Sound better. You are going to be more motivated to practice and feel better about your playing if you like the sound that comes out of your whistle. c) Have a higher resale value. If in the end you decide the low whistle just isn't for you, you'll have a better chance of recouping some of your investment. Conversely, if you do stick with it, you'll have more money to put towards an even better whistle later on.
                    With this in mind, my current recommendation for a low whistle that would be good for a beginner (and I reserve the right to change my mind at any time as I try out new whistles) is a Chieftain by Kerrywhistles. These are excellent whistles for a variety of reasons, which I intend to address on the Instrument Reviews section of this website and will therefore not repeat here.  Price wise, they tend to fall about in the middle when compared to other low whistles. At the time of this writing, a non-tunable low D Chieftain could be had for $180.00 US and were available directly from the maker for 115 lbs sterling. If that's just a bit out of reach financially, my second recommendation would be either a Kerry or a Dixon abs (for more info on these whistles see the Makers section).  Keep in mind that any of these whistles can also be found used for less on ebay and for private sale on the Chiff and Fipple forum website. The Irish Flute store also often has good deals on nice used low whistles.
                    For those for whom money is very much a going concern, or for those who subscribe to the first school of thought mentioned above, there are a few low whistles, generally made from PVC, going for anywhere from $100 down to $25. These include Brady whistles from Hawaii and Jubilee whistles (see the Makers section for more details and contact info). Or, if your feeling handy, you can make one yourself out of PVC using the detailed instructions Here, kindly given by Dr. Guido Gonzato of Italy.

3. Should I learn the "High" whistle before I learn the Low whistle?
                    It is a common misconception, in my not so humble opinion, that one should learn how to play the "high" whistle before learning how to play the low whistle. While it can certainly be argued that learning to play the high whistle may be a somewhat easier task, being able to play one does not necessarily give you a leg up on learning how to play the Low whistle. High whistles are generally played using the pads of the fingertips, where low whistles are generally played using the pipers grip (see Technique section).  Having instilled into ones muscle memory how to play using the fingertips, one would then have to "re-train" their fingers, compared to a complete beginner who would just learn the pipers grip from the start. Further more, not all fingering on a Low whistle is exactly the same as a High whistle, and the air requirements and breath control required to play each instrument is very different as well. This is not to say that a High whistler cannot or should not learn the Low whistle, simply that no one should feel obligated to learn the high whistle in order to learn the Low.
                    But most importantly, if you, like myself, are drawn to the Low whistle for it's intrinsic attributes, and maybe feel that High whistles are, well, too high (dare I say shrieky?), then why waste your time learning an instrument that you're not really interested in playing and just go straight for the good stuff!

4. Who played the Low whistle on the
soundtrack to the movie "Titanic"?

                    The Low whistles heard in the soundtrack to the movie "Titanic", including the song "My Heart Will Go On" sung by Celine Dion, were Chieftains played by Tony Hinnigan (see Players section) Tony has pretty much become the go-to man for whistles and other world flutes in general for movie soundtracks these days.

5. What Low whistle did Davy Spillane play in Riverdance?

                    This has been a much debated and disputed topic. More in-depth details on this enigma can be found here at the Chiff and Fipple website. The bottom line currently is we don't know and he's not telling!
