rhythm, pitch, and frequency

According to the American National Standards Institute,
pitch is the auditory attribute of sound according to which
sounds can be ordered on a scale from low to high. Since
pitch is such a close proxy for frequency, it is almost
entirely determined by how quickly the sound wave is making
the air vibrate and has almost nothing to do with the
intensity, or amplitude, of the wave. That is, "high" pitch
means very rapid oscillation, and "low" pitch corresponds to
slower oscillation. Despite that, the idiom relating
vertical height to sound pitch is shared by most
languages.[10] At least in English, it is just one of many
deep conceptual metaphors that involve up/down. The exact
etymological history of the musical sense of high and low
pitch is still unclear. There is evidence that humans do
actually perceive that the source of a sound is slightly
higher or lower in vertical space when the sound frequency
is increased or reduced.

Some types of parrots can know rhythm (Anon. 2009).
Neurologist Oliver Sacks states that chimpanzees and other
animals show no similar appreciation of rhythm yet posits
that human affinity for rhythm is fundamental, so that a
person's sense of rhythm cannot be lost (e.g. by stroke).
"There is not a single report of an animal being trained to
tap, peck, or move in synchrony with an auditory beat"
(Patel 2006, cited in Sacks 2007, 239–40, who adds, "No
doubt many pet lovers will dispute this notion, and indeed
many animals, from the Lippizaner horses of the Spanish
Riding School of Vienna to performing circus animals appear
to 'dance' to music. It is not clear whether they are doing
so or are responding to subtle visual or tactile cues from
the humans around them.") Human rhythmic arts are possibly
to some extent rooted in courtship ritual.

i agree, try playing a chord for a minute with a pad that
covers the full range of frequencies, then put a bandpass
filter over it, cutting the low range of frequencies will
make it sound slower or faster other than timbrically
different.

Given that you can transfer kinetic energy into heat, and so
on, and can thus say that heat is more energetic than cold
etc .... I wonder if it would be fair to say that
high-pitched tones are more energetic than those of
low-pitch (assuming that something which is fast is more
energetic than something which is slow)

amplitude is equally important. if your amplitude is tiny,
even a high-frequency wave won't carry much energy.

there are all sorts of levels of scale to this. like: it's
not some abstract, mathematically-perfect waveform that we
hear, it's waves of compressed air in various patterns

is rhythm the same thing as pitch, simply on a much "larger"
scale?

Tipper was "discovered" as a teenager DJing in a London
nightclub by soon-to-be manager Richie Warren. Their
earliest conversations centred on bass frequencies and
rhythms underlying beats, and they began researching the
science involved in creating the most effective dance
music.

When it comes to pitches the oscillation is usually
portrayed as being very regular. Even this is an
idealization and it's in reality only a fairly and not
perfectly regular wave-form, it seems that for a specific
pitch to appear there needs to be a regular pattern.

However, for something to qualify as "rhythm" it doesn't
need to be regular in that strict sense. ... So
this would be identifiable as a rhythm, but it's
also not regular.

... So I'm skeptical about treating pitch as rhythm on a
small scale. But maybe I'm wrong and pitch actually dosn't
need to be that regular so we hear it as a specific pitch,
HMM.

My guess is when "beats" get as fast as like a c5 note, then
instead of adding squarepusher style detail/mutations, it
becomes more like a "color" and the main way to make it
interesting is to blend it with other colors like a c5+an
e5. If you play a c and a d together its sort of weird if
you think of it in terms of a beat because what you're doing
is playing 2 simultaneous beats, each a different tempo (at
a really small scale). Normally large scale beats follows a
single tempo, but often a good sounding "4/4 beat" or
whatever might have an "repeating every 3rd time unit" part
in it which usually sounds good and is sort of a different
simultaneous tempo. When playing with modplug tracker, I
noticed you can make a, say, 128 time unit squarepusherish
beat with interesting complexities/uniqueness/mutations in
it. Then speed it up to like 4x faster and divide into like
8 chunks. Each chunk makes a pretty good percussion beat
unit on its own, and since it's made of an underlying slower
beat, you can mutate that slower beat and re-save the chunks
to make the chunks mutate in some way. Or something. I guess
I should try to make a normal beat except in multiple time
signatures at once, to emulate playing a c+d+e etc note
does, except on a larger time scale. Or something.

And I do kind of suspect if a song is mainly in the key of
c. Then maybe the tempo of the song should be an exact
multiple of the c frequency, or maybe the song tempo and a
note frequency tempo are too far away to notice. But that
way you could make a beat and constantly double the detail
and eventually the beat speed would match the tempo of the c
note (but not the d note etc, but assuming a song is mostly
based on c). I bet all this "music" is some sort of human
computation harvesting that governments can later use for
mass hypnotization. Like if you record the words "buttfuck
your grandma" each as syllables, then construct each
percussion unit out of these syllables at a micro scale,
will the resulting fractal memetic buttfuck make you totally
insane? It's like you could encode an entire encyclopedia
into a song this way and learn at a hyper rate
subconsciously just by listening to a song. This is how
machines will communicate probably. Well they'll keep the
encyclopedia songs for themselves and the weaponized
buttfuck songs for us.

the way that man has collapsed the harmonies into trumpet
notes is impressive. there was a moment where he paused for
a moment, and i knew what was coming in the song. i thought:
shit, how he going to handle this? he's painted himself into
a corner. and this was his answer.

anyone into programming the 303s should take note of how
trumpet man took that jawn monophonic.

that is the thing with trackers. there's usually at least
once per trax when i want some suspenseful airtime and so
i'll tick the pattern length up a few notches. boom, we're
off the grid. sort of

if you have a pattern full of sampled breaks looping really
fast like you described, and gradually slow it down, down,
until you hear just the first drum hit, then a bit more...
dit. dit. dit do. dit dooodah. dit doooodah deet.

is this like the feeling of a fan blade spinning down? or
perhaps a being made of pure sampled waveforms
existing in a dimension above spaceland accidentally
stubbing his toe into the universe of your trax? the answer
is yes

so i was a bit stuck on this track i was gonna call "crisp
ripple" when the words of GladOS floated up into my brain:
all you have to do is look at things objectively, see what
you don't need anymore, and trim out the fat

frequency is a technical thing relating to harmonic
content,
pitch is our personal perception of the harmonic content.

in a chord, the root note typically determines the perceived
"pitch" of the chord. if you play a C-Maj chord -- C-E-G --
you perceive the pitch of the chord as being C overall, even
though there are also E and G notes.

if you introduce rhythm, though... press E first, hold it,
wait... press G, hold it, wait... then press C.... then you
perceive it as a series of individual pitches, as opposed to
a unified chord of a single pitch. also known as a melody

I wonder if you play C E G B, ( C major seventh) equally in
velocity

Then you reduce the velocity of only note 'C' to 90 percent
...80 percent 70 percent

I wonder how much you need to reduce C before it becomes E
minor?

I suppose it is different for each individual, as you say
"perceived pitch".

high pitch/low pitch metaphor: a sound source and falling
under gravity will have a higher pitch if it is above you,
and a lower pitch if it is below you due to the doppler
effect, that probably has something to do with it.
