comment choisir sa poche de cornemuse

Plus d’aisance avec la tenue de la poche …. plus de concentration possible sur le doigté, le souffle !!! 

This is a guide to the dimensions of different brands of bagpipe bags on the market. These measurements should help you compare and select a bag that is appropriate for you. Height below represents the meaurement taken, while the bag is laid flat, from the fold at the top of the bag down the widest part of the bag middle to the opposite side. Length is the full length of the bag from tail end to the tip of neck, though the effect of this measurement may vary a bit if the bag is a swan neck. In the case of a swan neck, the bag should be considered equivalent to a somewhat longer bag.

 

 

Please keep in mind that there will be some variation in the manufacturing of bags. While they should be fairly uniform, most are stitched by hand feeding the material through a heavy-duty sewing machine which results in a bit of variation. Plus most materials will shrink and expand some depending on temperature and humidity. Just don’t be surprised if a bag is off by the width of your finger.

Also be aware that there will be differences in the diameter of bags with grommets (stock collars) versus bags that are tied in. A bag requiring a tie-in will « lose » material from its effective diameter in order to hold the stock in place. For otherwise equal bags, a collared bag will have a larger effective diameter.

Makers with grommeted bags may position the grommets futher forward of what is considered standard, such as the Livingstone bag made by Ross. Others, such as the Willie McCallum bag by Bannatyne may alter the cut of the bag to better suit some body shapes.

 

 

Selecting a bag size for you

Probably the most common mistake pipers make is getting a bag that is too large for them. Things that affect appropriate bag size are overall arm length, chest shape, and blowing technique. If you are having trouble comfortably reaching the chanter (assuming your stocks are correctly positioned on the bag), or have a lot of pressure from the bag on the inside of your forearm, then your bag is too large. Sometimes a short, large chested person can have a custom longer bag made to compensate for a smaller circumference. Over the years a number of bands have mandated small bags for their members regardless of their physical proportions—small bags mean less air, less air means more reliable cut-offs. But bag size will also slightly affect the tone of your pipes, which may or may not be an issue for you. Some pipers swear that they get noticeably better resonance and tone with a larger bag. (Though if your bag is full of hoses, valves, water trap systems, car keys or other objects, all bets are off regarding a bag’s tonal qualities!) Others say they can blow less often with a larger bag. The best way to determine the ideal bag size for you is to simply try different sized bags. Short of that, consult your instructor, your pipe major, or favorite retailer for advice.

If you are wondering if your bag is too large, you can use a temporary « corset » to effectively shrink the size of your existing bag. A cut-off pants leg can serve the purpose or a swath of fabric sewn or securely stapled. Regardless of how it’s constructed, the diameter should be smaller than your bag. The « corset » is slipped over the deflated bag then the pipes are played. If you find that the smaller effective diameter is an improvement, then consider a smaller bag. If it’s not an improvement and you are still unhappy, perhaps investigate a different brand in a similar size.

Other things to consider

Aside from size and shape, there are other things which should influence your bag purchase decision. Obviously, one will be your budget. Also. whether moisture build-up is a concern. (Are you a wet blower? Do you play for long stretches? Do you play every day or multiple times each day?) If moisture is a problem, a sheepskin bag or a zipper/clamp bag with some form of trap or moisture control system could be for you. Also a consideration is if you play left-handed. Left-handed bags typically aren’t stocked by retailers and custom bags mean a delay in delivery. A traditional (no grommets) bag is a quick solution for such a restriction, since you can cut the stock holes exactly where you want. Which brings us to another consideration, are you comfortable with cutting holes in a bag and tying in the stocks? If not, pre-installed grommets are available as are tie-in services offered by many retailers
