What term refers to a systematic form or procedure for accomplishing a task?

The correct answer is "Method" because it specifically refers to a systematic way of doing something, encompassing the idea of an organized and deliberate approach to completing a task. In various fields, including music therapy, a method provides a clear framework, often based on theoretical principles, for implementing a process or intervention.

This clarity and systematic nature distinguish "method" from other terms. While "technique" often refers to the specific skills or actions within a method, "strategy" focuses on broader plans or approaches to achieving goals that may not be entirely systematic. "Procedure," although it can imply a sequence of actions, might not always capture the systematic nature that defines a method as comprehensively. Therefore, in contexts that require a structured and deliberate approach, "method" is the most appropriate term.
