So, this notebook contains
three different parts, that correspond
to three different lectures.
The first one is a more generic lecture
on harmony and then, towards the bottom
of the notebook, there are parts that
correspond to two lectures:
one on geometry, and one on rock harmony.
So I refer to these lectures for
all the details on what you're going
to see here. This is mostly a notebook
to show in practice how algorithmically
one can obtain all the structures that
we talk about in the lectures.
So harmony, you already saw
in the beginning, when discussing
compositional tools, that note,
for instance the object note, has a
method that is "harmonize".
Harmony here, in this context,
corresponds to the simultaneous
playing of different pitches and in this
particular part here, in this particular
cell, what we are doing, we harmonize
a sequence of notes using
the notes of the scale.
So we are harmonizing within the scale.
We could harmonize within the chromatic
collection, and some of these ideas are
discussed in the lectures, but in this
particular example, we are harmonizing
on a particular scale, in this case a
C Major scale. A C Minor scale, sorry.
And here it is:
Demonstration
So we talk about transposition also,
in the context of harmony, we talk about
the transposition along the scale,
the transposition along the chromatic
collection and the transposition along
the chord. So, this is an example of
a transposition along the scale.
And this is an example of a transposition
along the chord. Again, refer to
the lecture for the details on how this
is actually done. So this is the result of
such a transposition:
