Composite Drone Reed Adjustment

Composite reeds often have brass or wooden bodies and either plastic or cane tongues.  Wood and metal tongues have also been used and recently, people have experimented with carbon fibre.  The quest is on the find the material combination which gives the best drone reed!  The design I use is very stable and here I will describe how to make any adjustments you might need.  Reeds of other designs can be adjusted by following the same principles.

If your drones reeds have been made for  your pipes, they should stay in tune and play at an appropriate pressure indefinitely. However, environmental factors or knocks may lead to the need to make small adjustments from time to time.

If you have bought new reeds and need to set them up in your own pipes you might need to make some small adjustments to make them play at their best in your set.

The main reason you might wish to adjust your drone reeds is that they aren’t playing at a comfortable playing pressure.  You will know this because they either shut off and fall silent after you start them up but before you reach normal playing pressure, or that they don’t sound or start up at all.  The next most common reason to adjust them is because they don’t play at the correct pitch.  It is possible that the problem you’re having with them might be temporary so do give them a chance to settle to your playing environment for a couple of days before making any adjustments.

Before you make any changes it’s wise to check a few things-

  • Is the drone airtight – make sure there are no leaks where the drone meets the stock, where the slide meets the standing part or around the tuning beads or piston.
  • Is there any damage to the drone – check for cracks and breaks.
  • Is the reed seated firmly in the drone?

The reed design I make allows you to adjust either or both of the playing pressure of the reed and its pitch. All adjustments should be made in very small increments (less than 1mm at a time) as small changes can have big results. You might like to mark the position of the reed tongue and bridle on the body of the reed before making any changes. This allows you to put everything back as close to its original position as possible if necessary. If the reed doesn’t play, it might just need a little encouragement so try gently pulling up on the tongue a few times, and suck through the open end to get it going.

If you need to adjust pressure and pitch, always adjust pressure first.

Adjusting Playing Pressure.

The reed is set to play at a comfortable pressure (approximately 12” Water Pressure). If the reed starts to play but then shuts off before playing pressure is reached, the tongue needs to be opened slightly. If the pressure needed for the reed to play is too great the tongue needs to be closed slightly.

Hold the reed horizontally in front of you, with the reed tongue on top as in the picture. You will see that on the left the reed tongue is loose and there is a small gap between it and the body of the reed. The size of the gap is set by the position of the bridle ring which dictates where the reed tongue meets the body of the reed. To close the tongue slightly, move the bridle to the left. To open it slightly, move the bridle to the right.

Although this adjustment is done to manage playing pressure, you may notice a resulting change in pitch. If this can’t be managed by adjusting the drone sliders, then you may need to move on and adjust the pitch.

Adjusting Pitch

This is controlled by the length of the tongue from its bridle to its loose tip. If you wish to lower the pitch of the reed, make the tongue longer by pushing it to the left from its fixed end so that it moves under the bridle. Make sure the bridle doesn’t move when doing this or the playing pressure may change.

If you wish to raise the pitch, you need to shorten the tongue by sliding it under its bridle to the right. You can do this by holding the bridle in place and pushing the flat surface of the tongue with your thumb. Do not push the loose end of the tongue and it may bend out of shape.

Be patient
You may find you have to repeat or combine these operations over a few days until things stabilise, but with care you’ll soon have the reed set up how you like it.

How to Adjust Northumbrian Smallpipes Cane Drone Reeds

Cane Drone Reed

Northumbrian Pipes usually have cane chanter reeds, but the materials used to make the drone reeds are quite diverse.  Composite reeds often have brass or wooden bodies and either plastic or cane tongues.   Wood and metal tongues have also been  used and recently, people have experimented with carbon fibre.  The quest is on to find the material combination which gives the most stable drone with the nicest tone.

Although composite drone reeds can be very stable, many people find them rather loud and have described their tone as being perhaps harsher than reeds made from natural materials.  For this reason, many people still prefer the tone and volume only achieved when using cane drone reeds.

Cane drone reeds do take some practice to make and set up properly.  However, when set up they should stay in tune and play at an appropriate pressure indefinitely. However, environmental factors or knocks may lead to the need to make small adjustments from time to time.

The main reason you might wish to adjust your drone reeds is that they aren’t playing at a comfortable playing pressure.  You will know this because they either shut off and fall silent after you start them up but before you reach normal playing pressure, or that they don’t sound or start up at all.  It is possible that the problem you’re having with them might be temporary so do give them a chance to settle to your playing environment for a couple of days before making any adjustments.  Before you make any changes it’s wise to check a few things-

  • Is the drone airtight – make sure there are no leaks where the drone meets the stock, where the slide meets the standing part or around the tuning beads or piston.
  • Is there any damage to the drone – check for cracks and breaks.
  • Is the reed seated firmly in the drone?

Sucking Through a Cane Drone Reed

Rolling a Cane Drone Reed

Once you have made these checks it’s worth checking to see if you can coax the reed to play before you make any adjustments.  To do this, remove the sliding part from the drone and suck.  You can adjust your sucking pressure and try to get the drone started.

If this doesn’t work, try rolling the reed vigorously for a few seconds between the palms of your hands.  After this, repeat the sucking process.  It’s worth repeating these two steps several times before moving on.

Adjusting Playing Pressure.

As cane is a natural material, it is affected by temperature and humidity and the aperture between the tongue and the body of the reed may open or close. If this happens, the pressure needed to make the reed sound will change and the reed will be out of balance with the pressure needed for the rest of the set.

 Opening the Tongue Aperture

If the reed starts to play at low pressure but then shuts off before full playing pressure is reached, the tongue has closed and needs to be opened slightly.  This can be done by gently lifting the tongue until slight resistance is felt. Repeating this a few times will open the tongue and increase the air pressure needed for the reed to play.

 

 

Closing the Tongue Aperture

If the reed doesn’t sound properly at playing pressure, the reed may have opened, the pressure needed is too great and the tongue needs to be closed slightly.  Hold the reed horizontally in front of you, with the reed tongue on the bottom as in the picture on the left. Hold the tongue closed with your thumb and gently warm the hinge area of the tongue. This can be done by holding it about 15cm above a candle for a few seconds. When the reed feels warm (but still comfortable to touch) move away from the heat and keep the tongue held closed for 30 seconds while the reed cools. This should reset the tongue in a more closed position and reduce the air pressure needed for it to sound.

Be patient

You may find you have to repeat or combine these operations over a few days until things stabilise, and you may also find that the pitch of the drone changes with the pressure.  That’s fine, because you usually need to set the playing pressure before setting the pitch.  However, if you are using a reed that previously was fine you will probably find that the pitch is still within the acceptable range for the drone and you can retune it by adjusting the drone sliding part.  With patience, hopefully you will have coaxed your cane drone reed back to its rich, soft tone.

How to Adjust Northumbrian Smallpipes Chanter Reeds

Northumbrian Pipes Chanter Reed

Once set up in the chanter, a Northumbrian Pipes reed will hopefully be trouble free. However, they are affected by knocks, temperature and humidity and they made need some settling in time in a new environment.

The Chanter reed is made from Arundo Donax. This is a natural material. There are two vibrating blades and the opening between them is carefully set. This opening may open up or close down, or the pitch may change slightly depending on the environment you play in. This is normal and one of the challenges all Northumbrian Pipers live with!

If either your chanter reed goes out of playing condition for any length of time they may need some minor adjustment.

 

 

 

The reed needs to be positioned correctly within the chanter so that the chanter plays in tune. This can be confirmed by checking the octave between the top and bottom G notes.

  • If the top G is too sharp compared to the bottom G the reed needs to be positioned further out of the chanter.  You may need to add a couple of wraps of waxed thread around the Staple (the metal tube) at the base of the reed then re-insert it in the chanter.
  • If the top G is too flat compared to the bottom G the reed needs to be positioned further in to the chanter.  You may need to take away some of the thread wrapped around the staple.

There are two vibrating blades and the opening between them at the tip is carefully set. However, this aperture may open up or close down, or the pitch may change slightly depending on the environment you play in. This is normal and one of the challenges all Northumbrian Pipers live with!

If the Chanter will only sound at high pressure the aperture has opened and needs to be closed slightly.

Before you make any changes it’s wise to check a few things-

  • Is the Chanter airtight – make sure there are no leaks where the Chanter meets the stock, the end cap, from your fingers or the key pads.
  • Is there any damage to the Chanter or Chanter Stock – check for cracks and breaks.
  • Is the reed seated firmly in the Chanter?

Closing The Aperture of a Smallpipe Chanter Reed

Hold the metal wire bridle around the base of the reed and gently squeeze your fingers and thumbs together. This will close the aperture slightly.

 

 

 

 

 

 

 

If the Chanter reed cuts out before full playing pressure is reached the reed has closed and needs to be opened slightly.

Hold the sides of the metal wire bridle gently (you might need some pliers). Gently squeeze and the aperture will open slightly.

 

 

Both of these operations are very delicate and it’s easy to damage a reed is they are done too roughly.  Ideally, the first time you do this you will be guided by someone who already knows how to do it.  However, if you are careful you can learn to do this safely and if done properly either or both can be carried out, testing the reed as you go, until you have the reed adjusted to your liking.
