Final answer:
The statement is false as resolving issues can impact multiple aspects of an individual's life, not just their music performance.
Step-by-step explanation:
The statement that when clients are working towards recognizing and resolving issues within each of the dimensions, only their music performance will be affected is False. Working on personal issues within any dimension of one's life can affect various aspects beyond just music performance. This could include their emotional well-being, interpersonal relationships, physical health, and even professional development. For instance, if someone is dealing with anxiety, resolving this issue may improve not only their ability to perform music but also their overall functionality in everyday tasks and interactions with others.
