Conventions

General

 

In JAZZ several new constructs (conventions) are active. In order to address them, we must give it a name. Because of our sympathy for the big band music style, we like to honour some great jazz musicians by using their names to address those conventions.

We also list and refer to existing conventions that we use in this JAZZ system.
