Here are some collections of information about the interplay between music and mathematics. I have collected a bibliography of such items as they float past me in cyberspace, and I went hunting for references in the reviewing journal Mathematical Reviews for mentions of music. In addition I am interested in a few other specific topics.
Special note to students: I am delighted that so many people seem to find this page when they are considering illustrating the connections between music and mathematics. Evidently this relationship has been explored in quite a few Science Fair projects; it is the basis for a number of classroom modules prepared by student teachers; it is the theme for essays in many general-studies courses in music or mathematics departments. At least, so I must surmise from the flow of mail!
Yes, I am pleased that so many people find this topic interesting and I hope to hear about novel angles from which you will study it. But please, before you write to me, make sure you have something specific to tell me or ask me about, and make sure the question you ask isn't already answered here. As much as I like to yak about these ideas, I grow rather testy when I get mail which simply says "Saw your website; can you suggest a science fair topic?", or "Can you find any other way to explain to me why there are 12 notes in a scale? I need an explanation by tomorrow". I'm not hiding anything from you: everything I know is already here -- I can't "send you something else"; and I've already made it as math-free as I can without losing sight of the coolness of the math involved -- I can try to clarify a passage or two but won't "make it all really simple".
Let's do it this way instead: once you have explored some new twist to these ideas, send me a summary or a URL and I'll put it here for others to share and enjoy -- OK? Sample exchanges
Another science fair project: abstract and full paper [LONG -- ZIP archive]
A similar report has been updated by its author and is no longer here at this site but cn be found here
With that in mind: read and enjoy what's here, and write if there's any
appropriate comment or question.
A frequently-asked question is, why are there 12 tones
in an octave? The answer has to do in part with the nature of sound. (It also has to do with the human
perception of sound, a delightful analysis of which I saw somewhere in
a discussion of compressing audio data onto audio CDs, but I can't
remember where I saw this -- ring any bells with you?) This in turn
raises some questions about the theory of
chords and so on. (This reference includes a discussion of
tuba-playing which, as it happens, is of personal interest to
me. There are also further information and some corrections elsewhere.). This information is also useful in piano-tuning. (I do it but I haven't checked
these references. Here is more information.)
There are other places to look on the web for readings and samplings of
tunings, more from a musician's perspective than a mathematician's. See
e.g. John Starrett's Microtonal Music Page,
and some comments about tuning and musical "color".
More microtonal tuning links are in a letter I received.
Just for fun I tried an alternative tuning of the scale.
Odds and ends about tunings:
Historical Tunings on the Modern Concert Grand
What many suspect seems to be true -- that there is a connection between music and the learning of math. Here is a link to
commentary about this connection, from MENC (the (U.S.) National Association for
Music Education). There are other studies that have been done, e.g.
University of Sarasota Study (Jeffrey Lynn Kluball); East Texas State University Study (Daryl Erick Trent); here is a AMC web page.
Even brain researchers are getting into the act.
One of the most publicized links between music and academic subjects
(including mathematics) is the "Mozart effect": the claim that exposure
to certain types of music -- especially exposure to _early classical_
music, very _early in life_ -- can lead to improved performance on
test scores, including tests of spatial visualization, abstract reasoning,
and so on.
I cannot comment authoritatively about the validity of this claim. On the
one hand, I myself had considerable exposure to music of this type, and indeed
do well with mathematical and other abstract tasks; this association seems
fairly comon among people of my acquaintance. On the other hand, I am
extremely skeptical of proposed "scientific truths" which are discussed
in the absence of thorough experimentation, analysis, and corroboration;
I am particularly dubious of truths expounded by those who stand to
profit from their popularization.
For further reading, you might follow some Internet links regarding
the Mozart Effect. Capitalized, it refers to
a book by Don Campbell, complete now with its own "Resource Center" and
web site. For a contrasting point
of view, you might consult, say, Steven Halpern's site or the Skeptic's Dictionary. I was asked to compare the
conflicting claims at these sites; here is my response.
Perhaps a better response ...
There are a couple of other connections between math and music.
Check out this
tidbit about Bartok's music and this
intermarriage between math and music. (I'm still
waiting for someone to set me straight on this one.)
A new twist: mathematical proofs set to music! (No, it's not "Deep Truth", but
it is kind of fun!)
Some other additions to the odds-and-ends file:
Some good reflections and book reviews on the math-and-music theme.
There are other places on the web to look for math'n'music information;
most of the links I could mention are already e.g.
here.
Here's a discussion of the acoustics of the piano. (On the other hand,
I can't help but be flummoxed by the
International Society for Mathematical and Computational Aesthetics !)
Just for good measure, I'll throw in a few links to sites which
offer something musical (mathematical or not). I should probably
start with a link to Music
Resources on the Internet and specifically a Welcome to the World of Classical
Music I saw a link to some PC software -- at
that site you'll find many other competing products; I have no
recommendation.
Finally let me suggest this page of
Pathways between Mathematics and the Arts
for some explorations of the links between mathematics and the visual arts.
(There are some more themes there relating mathematics and music as well.)
