What does the iso principle refer to in music therapy?

The iso principle in music therapy is fundamentally about matching the music to the client’s current emotional state or mood. By doing so, the therapist creates an environment that is relatable and familiar to the client, allowing them to feel understood and validated. From this baseline, the therapist can then gradually alter the music to elevate or shift the client's mood, facilitating emotional processing and promoting therapeutic progress. This dynamic approach makes the iso principle a powerful tool in music therapy, as it honors the client's feelings before guiding them to new emotional experiences. This method encourages a tailored therapeutic experience that can enhance engagement and openness in the therapeutic process, fostering a deeper connection between the therapist and the client.
