Final answer:
In Session view, the best way to mark sections is by a) using color-coded clips, which provides visual organization and easy navigation for different sections of your project.
Step-by-step explanation:
In Session view, a good way to mark sections is A) Using color-coded clips.
This method allows you to visually organize your project by assigning different colors to different clips, which can represent various parts of your composition like verses, choruses, or different instrumental sections. It helps with navigation and makes it easier to manage complex arrangements.
Option B, changing the BPM (beats per minute), relates to altering the tempo of the music, which isn't inherently useful for marking sections within the Session View. Option C, adding effects, and Option D, adjusting track volume, may be part of the production and mixing process but do not serve the purpose of visually distinguishing sections within the Session View.
Therefore, while options B, C, and D have their uses in music production, they are not typically utilized for marking sections within the Session View on digital audio workstations (DAWs).
