INTRODUCTION

The supertonic triad can substitute for the subdominant triad, both are similar in sound and function. The subdominant scale degree is the bass note when the supertonic triad is in first inversion.

In this lesson, you will learn subdominant substitution for supertonic, triad positions, doublings, uses, and part writing of the supertonic triad.

At the end of this lesson, you will be able to:

• Write voice doublings
• Part write the root position supertonic triad after the tonic triad
• Part write the first inversion supertonic triad following the subdominant triad
• Part write the supertonic triad progressing to the dominant triad
• Part write the supertonic triad progressing to the tonic six-four chord
• Part write to the first inversion supertonic triad to the first inversion leading tone triad
