In music, why are there so many octaves? I notice in some cases the octaves can be very pronounced, as in Beethoven's Fur Elise or Brahm's Lullaby. 140.254.136.179 (talk) 16:54, 7 April 2016 (UTC)[reply]

As it says in the intro to the Octave article: The octave relationship is a natural phenomenon that has been referred to as the "basic miracle of music", the use of which is "common in most musical systems" 217.44.50.87 (talk) 17:04, 7 April 2016 (UTC)[reply]

I think these answers are somewhat inaccurate. What makes different pitches sound good together is alignment of their

major triad

with the third overtone. That's why those intervals are so common in music.

The overtones are not exact multiples of the base frequency, so the best-sounding intervals are not exact integer ratios. This is independent of temperament. When a piano is nominally tuned to equal temperament, the frequency ratios between keys are actually somewhat larger than ${\displaystyle {\sqrt[{12}]{2}}}$. The ratio varies across the keyboard and depends on the characteristics of that particular piano. This is called stretched tuning. For instruments that can play arbitrary pitches, such as violins or human voices, good players/singers match the overtones by ear to lock in the chord. Either way, the result is an octave that probably isn't exactly 2:1. -- BenRG (talk) 20:27, 7 April 2016 (UTC)[reply]

There's certainly room for more than one approach to this question, and perhaps even more than one "right" answer. But overtones must not be strictly necessary, because intervals (sequential or synchronous) can sound good or bad (and be discriminated) even when only pure tones (i.e. sine waves) are being used, and those, by definition, have no overtones. Otherwise I think you're right, overtones are often important for understanding why we like certain intervals/dyads. SemanticMantis (talk) 21:28, 7 April 2016 (UTC)[reply]

Here is a study that investigates what intervals infants can discriminate [2], and asks if there is any evidence for "natural" intervals. They conclude there is something special about the fifth and the octave that is not simply a matter of enculturation (that is why they studied infants and not adults). They say:

So that's one potential answer: the octave is prevalent in music because the structure of our auditory system reacts in a special way to octaves. See here [3] and refs 17-20 therein for more about the special status of the octave in human auditory apparatus and perception. SemanticMantis (talk) 20:14, 7 April 2016 (UTC)[reply]

Why only Siamese cats used on Perry Mason TV series? Regardless of the episode--Careless Kitten, Caretaker's Cat or Silent Partner, ever time a cat appears in Perry Mason it is ALWAYS a Siamese cat!

Have you tried contacting the show's producers? ←Baseball Bugs ^{What's up, Doc?} carrots→ 22:42, 7 April 2016 (UTC)[reply]

I doubt the producers would even reply to just a lone fan.

There is a Perry Mason wiki though. It has edits as recently as yesterday. You might want to ask there. They would probably be the people who would have the most knowledge about the show who would actually respond to a fan's questions. Dismas|^(talk) 22:57, 7 April 2016 (UTC)[reply]

Isn't that show from the 50's or so? Those producers are long gone. No? If not, I doubt they are actively involved with the show nowadays in 2016. Joseph A. Spadaro (talk) 05:22, 8 April 2016 (UTC)[reply]

Among Perry Mason directors who are still alive, I did find Richard Donner, Vincent McEveety, Arthur Hiller, Arthur Marks and Robert Ellis Miller. But I'm not sure they'd respond to "What kind of cats did you use on Perry Mason and why?" --Jayron32 11:00, 8 April 2016 (UTC)[reply]

I agree. But would this be a question for the directors? Or the producers? Joseph A. Spadaro (talk) 18:13, 8 April 2016 (UTC)[reply]

Since shows of that era often saved money by reusing set pieces, extras, guest stars, etc., it wouldn't surprise me at all of they only had one cat "on staff", and that cat happened to be a Siamese. Or perhaps, they had one cat family "on staff", all of which were related, and Siamese. StuRat (talk) 05:36, 8 April 2016 (UTC)[reply]

Could it be You Rang? --Jayron32 00:40, 8 April 2016 (UTC)[reply]

I don't remember anything other than the groan MarnetteD linked to. "You rang?" was what he said when he was summoned by the family. Clarityfiend (talk) 02:32, 8 April 2016 (UTC)[reply]

He used to say "Follow me" when admitting visitors, and roughly drag off the gentleman's hat. --TrogWoolley (talk) 09:34, 8 April 2016 (UTC)[reply]

Good memory TrogWoolley and then they would get it back all crumpled up when the left the house in terror or bewilderment :-) MarnetteD|Talk 16:07, 8 April 2016 (UTC)[reply]

He squeezed their hat and head from above, and they then ducked down to avoid the pressure, leaving their hat in Lurch's hand. StuRat (talk) 18:19, 8 April 2016 (UTC)[reply]
