Assessment, stub class for now
editI assessed this as a mid-importance article for the Wikiproject Musical Instruments, because it has information that covers a wide range of instruments. I rated it a start class article because it is the needs more. It needs more inline references, to let people know where information in the article originates. If you improve it and want reassessment or need help or have questions, please drop me a line.Jacqke (talk) 20:13, 9 May 2018 (UTC)
Triangular Waves
editThe conical bore is associated with a timbre that corresponds to a generally triangular waveform, which is rich in both even- and odd-order harmonics.
A triangle wave contains only odd-order harmonics, so this is, at best, misleading and confusing. 71.178.60.90 (talk) 17:45, 21 November 2009 (UTC)
It was misleading which is why I've removed the mention of square and triangular waveforms. Any study of the waveform will show the missing even harmonics in the closed cylinder but nevertheless appear as a complex sine and not a triangle. I cited a physicist who has images up. Now to see if I can find some free images of the wave forms. Mwasheim (talk) 21:55, 18 January 2011 (UTC)
I'm in the process of producing some waveform and spectrograms of clarinets and saxophones. I wasn't sure what to chose as reference tones and would appreciate suggestions. 78.53.10.157 (talk) 09:50, 21 January 2011 (UTC)
Mostly cylindrical?
editWhat kind of criteria is "mostly?" Something is either cylindrical or it isn't. The images comparing trumpet and cornet clearly show the part of the bore approaching the bell to have a conical shape on both of them, though the angle of the conical portion of the trumpet is more shallow.
Now, ok, I understand that terminology often isn't rational, and I could believe that the convention in the musical world might be to call conical sections that are of a certain shallowness "cylindrical". But if so, this really needs to be explained, and if possible, the cut-off for considering a bore cylindrical should be described.
It seems like it ought also be noted that it is not the entire bore that is conical, necessarily, in a conical bore instrument but only a portion of it's length.
