## Key takeaways
- Decide the musical reason and the still anchors before you make any sound move; stillness is what makes motion readable.
- The Movement Library holds more than 1,296 movements in eleven categories, auditioned with a 440 Hz tone or the stem in HRTF 3D.
- Apply Movement sets a starting position (Keep Position, Center First, Around Head) and a scope (Entire Track, Specific Sections, Custom Time Range).
- Harmonic Movements tie motion to pitch, energy and sections, while Spatial FX and A/B/C Compare help you test the result.

In this lesson: You will learn when a sound should move and when it should stay still, browse and audition the Movement Library of more than 1,296 spatial movements, apply a movement to the whole song, to sections or to a time range, and shape melodic motion with Harmonics. You will also use the Spatial FX switches and the arrangement editor.

Movement is the most exciting tool in immersive audio and the easiest to overuse. A mix where everything spins is not immersive; it is tiring. The listener cannot tell which motion matters, so none of them do. The opposite is just as wrong: a mix where nothing moves wastes the medium.

Echoes, the reference mix you studied in the classroom tour, shows the balance. Bass, lead, snares and impacts form a still front stage. Only the arp, the risers and the transitions move. Because most of the scene is stable, every motion reads as an event. This lesson teaches you to design motion the same way.


## What you will learn

- Three questions to ask before you make a sound move.
- How the Movement Library is organised and how to audition a movement.
- The three starting positions and three time scopes for applying a movement.
- How to fine-tune orbit radius and speed, and when to use Set Position instead.
- How Harmonic Movements tie motion to pitch, energy and sections.
- How the Spatial FX switches and the arrangement editor support your plan.
