New Empty Project ⇧⌘N
Creates a new, empty project. You are presented with the project creation panel where you can choose from templates. The simplest project is a single audio track.
Each project has project properties including the project tempo, time and key signature, and more. You can edit some project properties in the Project Chooser when you create a project, and change them later while you’re working. For full details about project properties, see Logic Pro project properties overview.
