What does the iso-principle in music therapy focus on?

The iso-principle in music therapy is centered around the idea of matching the music to a patient's current emotional state or mood. This approach recognizes that individuals often respond better to music that reflects their feelings, as it can create a sense of understanding and validation. By aligning the therapeutic music with the patient's emotional experience, the music therapist facilitates a deeper emotional connection, making it easier for the client to engage in the therapeutic process.

This principle is rooted in the belief that music has the ability to mirror emotional experiences and that such matching can lead to emotional release, processing, and ultimately, transformation. For instance, if a patient is feeling sad, playing slower and softer music that reflects this mood can help them feel understood and less isolated. Once the patient has processed their feelings, the therapist may then gradually introduce different musical styles or tempos to encourage a shift in mood or promote positive emotions.
