The beginning of the Prelude is a slow crescendo that builds up from silence. The listener thus hears the gradual birth of the music. This part reveals almost nothing.
The main sound fragments used in the piece are not introduced in the order in which they will be used in the body of the work. Listeners are thus spared repetitiveness.
The Prelude enables listeners to discover some of the sound materials that they will hear later in the piece in varying forms and in a different order.
The Prelude concludes with a decrescendo ending in silence. The whole Prelude is in mono, which makes the spatial opening look like the raising of the curtain at the beginning of the second part.
Creation of the PreludeSince the choice is to keep the Prelude in mono, you will need to change (or at least check) the Audacity setting in File/Preferences. Once set, all new tracks will be in mono.

Throughout the Prelude, texture is built solely by pasting these materials onto the Audacity sequencer tracks. No effects are applied.
A practical tip before you begin. Arrange the window containing the sounds next to the Audacity window. The software automatically creates a track when you drag-and-drop a sound file.

The first sound is “tocaigu.mp3”. It is automatically placed at the beginning of a new track, which takes the same name as the sound file.
Picture: The name of the track and sound fileTo create a space before the next sound imported onto the same track, you must first insert a silence.
Sound:: “tocaigu.mp3” and “preludeaaa.mp3”
Picture: Inserting a silenceThen you simply continue placing the sounds, at first with plenty of space between them, then closer together [Editing].

Picture: Time Shift ToolThe cursor becomes a double horizontal arrow. You use this tool to shift the sound horizontally on the track.
Picture: Shifting a sound on a trackAt the end of the Prelude, events increase in density. If you place the cursor on the lower edge of a track, it becomes a double vertical arrow. It then allows you to zoom vertically, i.e. to change the height of this track (situated above the cursor). [Mixing]
