A music therapist must plan group music therapy carefully to meet the unique needs of each individual participant while at the same time creating a therapeutic atmosphere for the group as a whole. Effective group music therapy sessions often balance the following factors: 1. Therapist-directed vs. client-directed activities, 2. Waiting turns vs. simultaneous participation, 3. Making choices vs. following directives, 4. Active vs. calm, 5. Improvisation, spontaneity vs. structure, 6. Familiar music vs. new experiences, and 7. Success-oriented activities vs. challenging activities. — In Harmony, Strategies for Group Music Therapy.
