Merger from Diapason#Organ stop and String stop

I proposed this merger because Diapason itself seems to be a glorified disambiguation page, and half of the information in its Organ stop section is already in this article. String stop does not provide much helpful information; the topic is quite narrow anyway and doesn't, in my opinion, merit a full article. I think it would be better if the information in both of these articles was used to expand the respective subsections of the Tonal groups section of this article. —Cor anglais 16 (talk) 13:38, 12 March 2007 (UTC)

Re: String stop - straight merge and redirect makes a lot of sense.

Re: Diapason - merge Diapason#organ stop to this article, and merge Diapason#The diapason normal to Pitch (music)#19th and 20th Century standards. Create disambig, also including a link to Pythagorean interval.

Neither page should exist in their initial forms though, agreed. –MDCollins (talk) 14:15, 12 March 2007 (UTC)

Open and closed pipes

Today's edit on open and closed pipes parallels an edit on Organ pipe. Please see that discussion page for a brief explanation. --Ernst Grundke (talk) 19:05, 14 April 2009 (UTC)

Quite so. See Talk:Organ pipe#Open and closed pipes. Andrewa (talk) 20:44, 13 April 2017 (UTC)

String tone

William Sumner in 'The Organ" pub 1962 confirms that string tone pipes must be narrow, typically metal, can be wood, always 'small scale', and there's no mention of stopped string tone.

But considering that both stopped diapason and stopped flute pipes are fairly standard configurations, it's obvious for a not too knowledgeable but interested person to ask, what about string tone? And it seems to be only answered by the silence, which is rather unsatisfying.

So many configurations of flue pipe have been tried that it seems likely that someone has tried this, but if so the results were I guess underwhelming. I can see a possible problem... a string rank is already generally generally quieter than a diapason or flute of similar wind pressure, and a stopped rank is going to be quieter again, so it's probably not a terribly useful configuration.

But it would be good to find a source, either way. Andrewa (talk) 07:40, 13 March 2018 (UTC)

Flue

It would be useful to see the flue identified. I wonder whether "down" means literally "in the downwards direction" or simply "along", "through", or "into" in the clause, "Air under pressure (referred to as wind) is driven down a Flue...". I sense that the wind actually rises, passing through the flue, which is the large cylindrical ("resonator") portion of the pipe, so perhaps "down" is a bit misleading.

I too found this to be a rather odd wording. Someone not at all familiar with pipe organs and how they work might get the wrong impression. It has been changed to "through" rather than "up," as this also accommodates the occasional (not very common) horizontal flue pipe. Piperh (talk) 17:30, 16 July 2019 (UTC)

Length

I suspect it's actually the mass of the air in the column (ignoring density, composition, etc.) which determines the pitch, rather than the length, but perhaps "size of the pipe" would be sufficiently general to express the concept. If it were length alone, why not build all pipes similar in diameter? Unfree (talk) 09:32, 10 August 2009 (UTC)

As I understand it, the diameter of a pipe has a large part to play in its timbre. Thinner pipes have a more incisive, stringy tone with many partials, while wider pipes emit a tone with fewer harmonics emphasized but with lots of fundamental; the effect in this case is a warm, rich, even "fat" or "tubby" when dealing with very wide pipe diameters. This is (envisioned to be) discussed at organ flue pipe scaling. Hence, "size of the pipe" does not adequately describe how the concepts of length and diameter work in pipe making. —Cor anglais 16 12:52, 10 August 2009 (UTC)

Regal class?

If flue pipes are divided into "Principal", "Flute", "String" and "Hybrid" classes as stated in the Stop section, what is meant by "regal class" in the Undulating stops sub-section? MegaPedant (talk) 18:43, 16 October 2009 (UTC)

A regal-class reed simply indicates a short resonator; I've made the edit. —Cor anglais 16 14:35, 19 October 2009 (UTC)
