History:Object Model/Recording Object

The Performance Object

This page describes the Performance (aka Recording) object and its role in the ObjectModel.

Definition

A performance of a song's composition is the stage were the first audible representation of a composition is created and -- for our purposes more important -- recorded. This means, a recording of a song in a studio or a live performance of a song is its performance. The result of a performance is raw audio material that is stored for further processing.

Boundaries

Boundaries to the CompositionObject

When the composition is transformed to an audible representation that is recorded for later (optional) editing, it becomes a performance/recording.

Boundaries to the MixObject

If the recorded audible data is changed in any way (edited) it is no longer a performance.

Relationships

Relationships to the CompositionObject

• A ../PerformanceObject is based on exactly 1 ../CompositionObject

• Each different performance is created from one composition as its source.

Relationships to the MixObject

• A ../PerformanceObject is the source of 1 to many ../MixObjects

• The musical data that is the result of a recorded performance, can be used to create different versions or mixes of the performance. Even the so often called "album version" or "original version" is such a version or mix because it involves the editing of the raw data.

Relationships to the ArtistObject

• A ../PerformanceObject is related to 0 to many ../ArtistObjects

• A performance or recording can be done by one or more individuals or bands. Those are the performing artists of the recording. There might be recordings without a performing artist, e.g. nature sounds. This relationship defines the ../ArtistObjectRole Performer.
