# Mathematics and Music

*David Wright*

Many people intuitively sense that there is a connection between
mathematics and music. If nothing else, both involve counting. There
is, of course, much more to the association. David Wright's book is an
investigation of the interrelationships between mathematics and music,
reviewing the needed background concepts in each subject as they are
encountered. Along the way, readers will augment their understanding of
both mathematics and music.

The text explores the common foundations of the two subjects, which
are developed side by side. Musical and mathematical notions are
brought together, such as scales and modular arithmetic, intervals and
logarithms, tone and trigonometry, and timbre and harmonic analysis.
When possible, discussions of musical and mathematical notions are
directly interwoven. Occasionally the discourse dwells for a while on
one subject and not the other, but eventually the connection is
established, making this an integrative treatment of the two
subjects.

The book is a text for a freshman level college course suitable for
musically inclined or mathematically inclined students, with the
intent of breaking down any apprehension that either group might have
for the other subject. Exercises are given at the end of each
chapter. The mathematical prerequisites are a high-school level
familiarity with algebra, trigonometry, functions, and graphs.
Musically, the student should have had some exposure to musical
staffs, standard clefs, and key signatures, though all of these are
explained in the text.

#### Readership

Undergraduate students interested in math and/or music.

#### Reviews & Endorsements

This book is written with a different spirit. It reviews some basic concepts in both mathematics and music from the very beginning, presuming no background in either of these fields. ...Wright has packed an ambitious overview into 150 printed pages.

-- Springer Science & Business

All the necessary mathematical and musical theory and notations are introduced as they are needed, and the book is clearly illustrated, easy to read and learn from, and certainly to be recommended. ...the author's treatment of the subject is down to earth and realistic, and I certainly plan to use the book in future courses that I teach on the subject.

-- LMS Newsletter

In classroom use, this polished book gives mathematics students a demystification of music theory's prerequisites and music students a motivated selective review of high school mathematics.
