****TETRACHORDS****

*The early Greeks devised scales which had only four notes, or tones. These scales were called TETRACHORDS, the word "TETRA" meaning four.

*The tetrachord progression of ascending tones is as follows:

Whole Step - Whole Step - Half Step (W-W-H)

Example of a Tetrachord:

C - D - E - F

or

Bb - C - D - Eb
