Key Concepts

This chapter introduces three key concepts demonstrating the flexibility of modal practice:

1. Relation to the Major Tonality - The technique of combining modes of limited transpositions with traditional major-key tonality through emphasis or mixing of materials

2. Modulation of a Mode to Itself - The technique of changing transposition levels within a single mode, creating harmonic motion while maintaining the mode's characteristic structure

3. Modulation of a Mode to Another Mode - The technique of moving from one mode to a different mode, creating large-scale harmonic transformation within the modal system
