In most cases, there is no music during a TRE (Tension and Trauma Release Exercises) session.
For me, it feels intuitively right with silence during more formal TRE sessions. Why is that?
The music may not fit what comes up for each person, or what “needs” to come up.
Music preferences are very individual. Whatever music played will be liked by some and disliked by others. Occasionally, with more experienced people, this can be interesting. Whatever comes up in relation to the music can be included in the session. For beginners, it may be better with no music.
Any music can be distracting from feeling sensations, looking at mental images, and hearing words.
If I do it on my own, I may do it while music is playing or even while watching a movie. I do it in just about any situation, if it feels right.
