Rhythm and Transforms is a book that explores rhythm in music, its structure and how we perceive it. The book will be bought by engineers interested in acoustic signal processing as well as musicians, composers and computer scientists. Anyone interested in the scientific basis of music from psychologists to the designers of electronic musical instruments will be interested in this book.

This is a beginning book of percussion pieces designed to assist the teacher in providing a hands on experience with the sounds of African percussion ensembles. The collection is based on authentic pieces of music, however ho attempt has been made to notate the improvisation and variation that are inherent in African Drumming . As with any oral tradition even within a recognized piece of music, there are changes and variations so that no one version is the “correct “ one. A CD is included with the book.

At first glance, mathematics and music seem to be from separate worlds—one from science, one from art. But in fact, the connections between the two go back thousands of years, such as Pythagoras’s ideas about how to quantify changes of pitch for musical tones (musical intervals). Mathematics and Music: Composition, Perception, and Performance explores the many links between mathematics and different genres of music, deepening students’ understanding of music through mathematics. In an accessible way, the text teaches the basics of reading music and explains how various patterns in music can be described with mathematics. The authors extensively use the powerful time-frequency method of spectrograms to analyze the sounds created in musical performance. Numerous examples of music notation assist students in understanding basic musical scores. The text also provides mathematical explanations for musical scales, harmony, and rhythm and includes a concise introduction to digital audio synthesis. Along with helping students master some fundamental mathematics, this book gives them a deeper appreciation of music by showing how music is informed by both its mathematical and aesthetic structures. Web Resource On the book’s CRC Press web page, students can access videos of many of the spectrograms discussed in the text as well as musical scores playable with the free music software MuseScore. An online bibliography offers many links to free downloadable articles on math and music. The web page also provides links to other websites related to math and music, including all the sites mentioned in the book.

With Freeman Kwazdo Donkor and Abraham Adzenyah. Based on four Ghanaian rhythmic groups (Sikyi, Adowa, Gahu and Akom), this book and CD will provide drumset players with a "new" vocabulary based on some of the oldest and most influential rhythms in the world. A groundbreaking presentation!
