  Event is the basic musical element. It's more or less a generalization of the MIDI event. Each note or rest, each key change or tempo change, is an event: there's no "note class" or "rest class" as such, they are simply represented by events whose type happens to be "note" or "rest". Each Event has a type code, absolute time (the moment at which the Event starts, relative only to the start of the Composition) and duration (usually non-zero only for notes and rests), together with an arbitrary set of named and typed properties that can be assigned and queried dynamically by other parts of the application. So, for example, a note event is likely to have an integer property called "pitch", and probably a "velocity", as well as potentially many others -- but this is not fixed anywhere, and there's no definition of what exactly a note is: client code is simply expected to ignore any unrecognised events or properties and to cope if properties that should be there are not.
