   I wonder if Anthony would agree therefore that since lots of the notes
   are sharp, a good starting point would be to pull the reed out a
   fraction?

   Hello Chris
   F+ is a variable thing but 90% of pipers seem to blend their pipes
   failry pleasantly at A=446. This is 8 Hz sharper than the chanter in
   question so I'd be disinclined to pull the reed out as a first step,
   especially as the chanter has a top B which is already 25 cents flat.
   I'd be interested to see the results of the cotton bud plunger trials
   before changing anything to do with the set up.
   Cheers

[NSP] Chanter Tuning

2011-02-06 Thread Anthony Robb


 From Chris Gregg:

  So that is why my pipes always sound out of tune, and I thought it
   was
  just poor musicianship on my part!
  The whole tuning thing is a bit of a quagmire, and as a solo
   instrument
  it is not a problem, but I would like to know how people get around
   it
  in recording sessions.


   Hello Chris

   This sounds to me as though your bottom G is a tad flat and that's why
   so many notes seem sharp.

   The other thing to say is that the chanter, in all likelihood, could be
   brought in tune with careful use of PVA glue (for sharp notes) and a
   scalpel fitted with an 11P blade (for flat notes).

   Before doing anything drastic, however, I would get to know your
   chanter's idiosyncrasies by removing the cotton wool plug, if there is
   one, from the bottom of the bore. Then I'd repeat your measurements
   (draw up a table) with a cotton bud inserted at set positions into the
   bore. I'd start off with the rounded tip in at 10mm then go up by 5mm
   increments to within 15mm of your bottom D (for a 7 key chanter)
   checking the tuning of each note as you go. Write down your results so
   the pattern can be seen at a glance. This will tell you how much effect
   the standing waves below each chanter note are affecting the pitch of
   each note. You might find one position will bring your chanter closer
   in tune with itself. If the cotton bud makes matters worse I'd insert a
   20mm narrow cone of cotton wool (point first) into the chanter and see
   if that helps.

   If you do need to resort to scalpel  glue I'd do this with the cotton
   wool cone to minimise standing waves interfering with your tuning.

   Let me know how you get on.

   With regards to recording sessions every group of pipers of pipers will
   have their own solution. As you say solo is fine as the piper can
   adjust where necessary. At the other end of the scale massed pipes are
   OK too because variations with 5 chanters or more tend to balance out.
   The trickiest we find is when 3 pipes are playing together. We found
   that recording the three chanters together without drones (live or
   recorded) works best as each of us listens out for what is happening
   with the other players and adjusts where necessary. Then drones are
   tuned to the chanters and added to the mix. This can mean up to 11.5
   mins of constant drone without fingering the chanter at all which is
   surprisingly tiring on the fingers. It also means that chanters have to
   be played at a fairly consistent pitch and in with each other without
   any external reference point at all. But then as we can see from the
   recent posts external references are often a hindrance rather that a
   help in that situation.

   I hope some of this helps but please remember no theories whatsoever
   have been used as a basis for this advice just 40 years mucking about
   with some of the loveliest chanters around (Burleigh, Gruar, Hedworth,
   Nelson and Ross) and nowt but my own lugs as final arbiter.

   Good Luck

   Anthony
