(back) Subject: Flute Celeste - What If . . . (X-posted fromTheat... From: <> Date: Mon, 5 Jun 2000 05:05:54 EDT   Hello John:   I have a Concert Flute Celeste happened just as you postulated. What a lovely sound it is. VEAGUE's answers are pretty much what any good organ builder would answer. Here's my 2 cents worth:   1) YES! I ended up with 3 identical sets of Concert Flutes and used just = 2. 2) I personally would lean toward taking the Celeste all the way up to = the top octave depending on the room acoustics and pipe voicing. 3) String and Flute Celestes are normally tuned sharp. This will make = for a brighter sound. As VEAGUE pointed out there are ranks tuned flat to get = that sinister effect. Some Celestes have a Unison, a Sharp, and a Flat for a really thrilling effect. 4) Celeste rates are much like trem rates and depth, it is somewhat subjective. The beat rate varies throughout the compass of the rank so = using a strobe device is not a normal practice. Too fast a beat and you sound = out of tune while too slow and the effect is lost depending on the speed of playing. I use a mechanical metronome set to one second clicks then count =   the beats each second for my initial set up. Starting with the 8'C = establish a nice gentle undulation that can be heard for one second. Next go to the =   top octave and establish a slightly faster rate of undulation that still sounds pleasant. Count the beats at each end of the compass. Pick a = number in between for the 2'C (middle C) and adjust it to that number. See how = it sounds. If OK then fill in the middle of the remaining 4'C and 1'C = octaves. Play chords after going up and down the entire compass several times with your eyes closed. Go into the listening area while someone plays test chords. If the echo and the acoustics match your efforts then you are rewarded. If not, start over! The bottom line is use your ear not your Peterson! 5) I did not like the Celeste going down to 16' on the Bourdon so I took = the second set and made it play a cross coupled resultant for a very effective =   32' stop. 6) VEAGUE points out same chamber placement but I recommend also keeping = the pipes separated by at least one or two ranks mimimum to keep them from pulling together. They should be on the same tremulant and regulator or = they won't sound well at all. The Celeste rank should be away from large = Opens, etc., or it will draw down in pitch and you won't have a Celeste.   Al Sefl Who would name his twin daughters Viola and Celeste...................

I had a feeling that the final judge would be = the ear, but I thought that a few roughly quantified guidelines might help a beginner. And that's what you gave me.   Interesting concept - a dedicated resultant rank. The Bourdons are cheap enough to consider it. And it would allow for separate voicing and regulation to get a more effective sound for your fake 32' rank.   John

From: "VEAGUE" <> Date: Mon, 5 Jun 2000 07:59:52 -0500   I agree that the two celeste ranks should be separated by a different rank in the middle. This will detere cross-beating between the unison and celested pipes.   As for the UndaMaris as a sinister sound (I love it!) , it indeed adds a little flavour to the mix. The Reuter in Paducah, Ky has celested ranks sharp and flat. All played together with the Vox-in-the-box gives a = warm-but sizzly chorus.   Tuning by ear is the only way to tune a good celeste. Afterwards, go back and correct any pipes that are wild.   Rick
