Polyharmony and Consonance


an architectural approach to large scale contemporary composition.

When we presented The Seventh Seal opera at the Conservatório de Tatuí, in November 2018, I did a series of seminars, focusing on different aspects of the production. During the composition sections, I had to answer a lot of questions regarding the harmonic language of the opera. These questions have led me to write a book that is intended to serve as a training manual for large scale composition, in an approach that tries to be as inclusive as possible.

Here you can download the Introduction of the book: Polyharmony and Consonance – an architectural approach to contemporary large scale composition.

I am looking for early readers. If you are willing to dive into the rest of the book: I’ll send a link to the full text to the first five dedicated musicians who are willing to retribute with comments on how I can improve the text.

If you want to dive into the subject: please send an email to: joao (at) brazilianopera.com.

The work on this book has inspired me to write a collection of Preludes and Fugues. In these compositions, I demonstrate several of the concepts of the book. There are piano and string quartet versions of it. Please email at the address above if you are interested in performing these.
