Apply a high-pass filter or reverb automation

Insert a high-pass filter plugin on the master track or the track(s) you want to affect. Automate the cutoff frequency to gradually rise from its starting position towards the end before the transition in a other part. This filtering effect creates a sense of closure and anticipation and refines the created transitions you can achieve similar effects by using reverb. Apply a reverb effect to the entire track or the elements you want to emphasize.  Increase the reverb level gradually as you approach the ending section. This enhances the sense of space and depth, contributing to the overall impact of the transition and acts as a glue effect which makes the song sounds more professionally.
