Most classical musicians, whether in orchestral or ensemble situations, will have to face a piece by composers such as Ligeti, Messiaen, Varèse or Xenakis, while improvisers face music influenced by Dave Holland, Steve Coleman, Aka Moon, Weather Report, Irakere or elements from the Balkans, India, Africa or Cuba. Rafael Reina argues that today’s music demands a new approach to rhythmical training, a training that will provide musicians with the necessary tools to face, with accuracy, more varied and complex rhythmical concepts, while keeping the emotional content. Reina uses the architecture of the South Indian Karnatic rhythmical system to enhance and radically change the teaching of rhythmical solfege at a higher education level and demonstrates how this learning can influence the creation and interpretation of complex contemporary classical and jazz music. The book is designed for classical and jazz performers as well as creators, be they composers or improvisers, and is a clear and complete guide that will enable future solfege teachers and students to use these techniques and their methodology to greatly improve their rhythmical skills. An accompanying website of audio examples helps to explain each technique.
