If you’ve been following Jovino’s Brazilian classes, you may have noticed that he occasionally mentions Hermeto Pascoal’s odd manner of notation. I recently came across this article.
I found it interesting and thought you might as well. Play through the examples. There are some lovely voicings that are keepers, as well as some that are a bit strident, at least to my ears. Enjoy!
