This modal ordering remains constant regardless of the major scale used.
Therefore, it can be used as an “algorithm,” a known value for comparative
problem solving, and used as a tool for identifying, constructing, and transposing
modes. In

Chapter 4 "Key Sense, Key Signatures, and The Cycle of Fifths"

modes will

be revisited and the Revolving Scale model will be used in conjunction with other
tools to perform these tasks.

The student should:

• Define modes and understand their historical significance.
• Know mode names.
• Understand the Associative Method and the Revolving Scale Method for

modes.
