Creativity is a difficult subject

16 Dec

j0437275The topic of creativity presents a very challenging subject to study.  Indeed, Margaret Boden, a professor of cognitive science at the University of Sussex who studies creativity from various perspectives, says that, next to consciousness, it is the most challenging phenomenon to make sense of in a materialistic world.1  Why is that?  We have a sound and straightforward etymological foundation for the word.  What is it that makes it so difficult to study?

Simply put, the word create means to produce or make something.  Create, in the intransitive sense, is to be creative meaning to have the quality of being able to create.  The “-ity” suffix forms a noun from an adjective.  Thus, we can say straightforward, that creativity is the possessed state, property and/or quality of being able to produce or make something.

Part of the challenge comes from the field itself.2  As with most fledgling fields of study, there are many personalities each with distinct ideas about the topic.  So, there are as many definitions of creativity coming from various academic domains.  For instance, we find definitions of creativity in the literature of business, cognitive science, computer science and artificial intelligence, the arts and also within education.3 The straightforward definition given here is an oversimplification of the entry on the word create in Webster’s Dictionary.

Another challenge comes from questions regarding the mechanism of creativity.  Whatever the definition of it, how does it happen?  How are creative acts achieved?  Why are some people apparently more creative than others?  What is the neurophysiology of creative behavior?

Also, is creativity possible outside of a social context?  Can the process of creativity be defined mathematically?

For, if so, then that process can be computed.

Musical Language

17 Nov

The folks at Radiolab have done several interviews – one of them with David Cope – talking about musical language.  Two of the interviews open the door to considering physiological foundations of experiencing dissonance and consonance in sounds.  One of these discusses dissonance and consonance in terms of brain chemistry.  The other discusses the similarities of tonal melodies that occur across various cultures and languages when addressing a baby or child.

Music from a Machine

13 Oct

David Cope teaches music theory and composition as well as classes in algorithmic computer music at the University of California, Santa Cruz.  One of his interesting accomplishments behind the (computer) keyboard is his development of EMI (standing for Experiments in Musical Intelligence), a computer program that develops music in a particular style given that which it learned from sample music.  In general, the music is classical in nature, but some have a modern composition.

His web-page, including MP3 files of the music, is online at http://arts.ucsc.edu/faculty/cope/index.html.

 

Our xylophone has been ordered!

A $150 Xylophone from EBay

A $150 Xylophone from EBay

For this project to support research in the area of computational creativity, we’re building a robotic xylophone.  Well, we’ve got the approval for funding and the xylophone has been ordered.  Naturally, this is exciting!  This means that soon, we’ll be opening a box like children at birthday parties, putting it together and playing with it.  It might actually get a little loud around the 2nd floor of Nedderman Hall for a few.

Now, the next order of business is to settle on the solenoids and get those ordered as well.  Perhaps, we’ll get one to test our construction ideas.  Brandon Skinner has agreed to help put together the controller.  His help is greatly appreciated!
