MUS 160 Lecture Notes - Lecture 1: Secondary Chords, Voice Leading, Major Chord
Document Summary
Secondary dominants are chords that are the dominant (v) chord of a certain key other than the tonic (i) key. For example, let the current key be c major. F major chord is the subdominant (iv) of the current key (c major). You can also think of the secondary dominant chord being the ii chord of the original tonic key. For example you can take c major, the dominant (v) would be g major, then you would take the dominant of that key, d. which is the second scale degree of c major. Secondary dominants sometimes deviate from the traditional voice leading rules. For example, with v7/v, it is common to lower the augmented fourth degree if the chord progresses to dom7. This causes a parallel motion by tritones (bar 1). V/v is a widespread chord; that is why the fifth degree of a key is rarely diminished the.
