MICHAEL SCOTT ASATO
CUTHBERT: Hi, there.

00:00:11.190 --> 00:00:13.190 align:middle line:84%
I hope you were able to
take a couple of minutes

00:00:13.190 --> 00:00:15.480 align:middle line:84%
to think about how you
might represent pitch.

00:00:15.480 --> 00:00:19.400 align:middle line:84%
I'm back at our camera,
hopefully a little bit better.

00:00:19.400 --> 00:00:24.590 align:middle line:84%
So what are the consequences
of the pitch representation

00:00:24.590 --> 00:00:27.290 align:middle line:90%
that we might choose?

00:00:27.290 --> 00:00:29.870 align:middle line:84%
That's what we're going
to be looking at now.

00:00:29.870 --> 00:00:32.119 align:middle line:84%
So let's say that
we decide to work

00:00:32.119 --> 00:00:38.420 align:middle line:84%
with the numeric
representation, p equals 440.

00:00:38.420 --> 00:00:42.500 align:middle line:84%
How would we represent, then,
a type of continuous pitch

00:00:42.500 --> 00:00:47.180 align:middle line:84%
like a glissando since
we only have one number?

00:00:47.180 --> 00:00:50.460 align:middle line:84%
Or even just thinking about
the performance perspective,

00:00:50.460 --> 00:00:54.890 align:middle line:84%
how do we represent-- how do
we go from a number like 440

00:00:54.890 --> 00:00:59.000 align:middle line:84%
into something that a performer
would be able to see on a staff

00:00:59.000 --> 00:01:00.210 align:middle line:90%
and play with?

00:01:00.210 --> 00:01:04.230 align:middle line:84%
And are we just going to have
a whole series of numbers?

00:01:04.230 --> 00:01:07.680 align:middle line:84%
So maybe the string bass thing
will be a little bit better.

00:01:07.680 --> 00:01:09.330 align:middle line:84%
But then how do
we manipulate it?

00:01:09.330 --> 00:01:12.260 align:middle line:90%
What does p plus 2 mean?

00:01:12.260 --> 00:01:15.140 align:middle line:84%
Are we just going to have a
whole bunch of Python errors

00:01:15.140 --> 00:01:21.253 align:middle line:84%
that we can never add
things together that way?

00:01:21.253 --> 00:01:22.670 align:middle line:84%
So what we're going
to be thinking

00:01:22.670 --> 00:01:26.640 align:middle line:84%
about in the first
group discussion is,

00:01:26.640 --> 00:01:31.970 align:middle line:84%
What are the consequences of
the particular representations

00:01:31.970 --> 00:01:33.920 align:middle line:90%
that we choose?

00:01:33.920 --> 00:01:37.880 align:middle line:84%
In other words, what
kinds of applications

00:01:37.880 --> 00:01:41.570 align:middle line:84%
can be done with a particular
representation that

00:01:41.570 --> 00:01:44.430 align:middle line:84%
can't be done with
another representation?

00:01:44.430 --> 00:01:47.420 align:middle line:84%
Another way of
putting it is, Which

00:01:47.420 --> 00:01:52.830 align:middle line:84%
stakeholders are
included or excluded,

00:01:52.830 --> 00:01:57.140 align:middle line:90%
depending on our representation?

00:01:57.140 --> 00:01:59.150 align:middle line:84%
So the next thing
I'd like you to do

00:01:59.150 --> 00:02:02.930 align:middle line:84%
is to think of
three different ways

00:02:02.930 --> 00:02:05.330 align:middle line:84%
that you might represent
pitch on a computer.

00:02:05.330 --> 00:02:07.980 align:middle line:84%
And then think about
for each of those,

00:02:07.980 --> 00:02:13.230 align:middle line:84%
what does this way do well, and
what does this way do badly at?

00:02:13.230 --> 00:02:16.740 align:middle line:84%
And then think about
the stakeholders.

00:02:16.740 --> 00:02:18.900 align:middle line:84%
The stakeholder
might be a musician,

00:02:18.900 --> 00:02:25.200 align:middle line:84%
or it might be a programmer, or
it might be a record producer,

00:02:25.200 --> 00:02:29.630 align:middle line:84%
or it might be somebody who
is more specific, like a rock

00:02:29.630 --> 00:02:31.700 align:middle line:84%
musician versus a
classical musician

00:02:31.700 --> 00:02:33.200 align:middle line:90%
or something of that sort.

00:02:33.200 --> 00:02:38.600 align:middle line:84%
And who are the stakeholders
who are excluded or included

00:02:38.600 --> 00:02:41.050 align:middle line:90%
by what you've done?

00:02:41.050 --> 00:02:44.000 align:middle line:90%
