Definition and notation

The normal diatonic major scale
Major scale
In music theory, the major scale or Ionian scale is one of the diatonic scales. It is made up of seven distinct notes, plus an eighth which duplicates the first an octave higher. In solfege these notes correspond to the syllables "Do, Re, Mi, Fa, Sol, La, Ti/Si, ", the "Do" in the parenthesis at...

Key (music)
In music theory, the term key is used in many different and sometimes contradictory ways. A common use is to speak of music as being "in" a specific key, such as in the key of C major or in the key of F-sharp. Sometimes the terms "major" or "minor" are appended, as in the key of A minor or in the...

 higher). However, each of the chords from ii through vi also has its own dominant. For example, vi (A minor) has E major (Dominant (music)#Triads) as its dominant. These extra dominant chords are not part of the key of C major as such because they include notes that are not part of the C major scale. Instead, they are the secondary dominants.

Below is an illustration of the secondary dominant chords for C major. Each chord is accompanied by its standard number in harmonic notation. In this notation, a secondary dominant is usually labeled with the formula "V of ..."; thus "V of ii" stands for the dominant of the ii chord, "V of iii" for the dominant of iii, and so on. A shorter notation, used below, is "V/ii", "V/iii", etc. The secondary dominants are connected with lines to their corresponding tonic chords.

Note that of the above, V/IV is the same as I. However, as will become clear shortly, they are not always identical.

Like most chords, secondary dominants can be classified by whether they contain certain additional notes outside the basic triad; for details, see Figured bass

. A dominant seventh chord (notation: V7) is one that contains the note that is a minor seventh above the root, and a dominant ninth chord (notation: V9) contains the note a ninth above the root. For instance, V7/IV, although it is a C chord, is distinct from regular C major because it also contains the note B flat, which is a minor seventh above the root of C, and not part of the C major scale.

To illustrate, here are the secondary dominants of C major, given as dominant seventh chords. They are shown leading into their respective tonics, as given in the second inversion

Normal sequencing or cadence

When used in music, a secondary dominant is very often (though not inevitably) directly followed by the chord of which it is the dominant. Thus V/ii is normally followed by ii, V/vi by vi, and so on. This is similar to the general pattern of music wherein the simple chord V is often followed by I. The tonic is said to "resolve" the slight dissonance created by the dominant. Indeed, the sequence V/X + X, where X is some basic chord, is thought of by some musicians as a tiny modulation

, a secondary dominant, along with its chord of resolution, was considered to be a modulation. Because the effect of modulation was so short, and did not sound like a real arrival of a new key, the two chords had a special name--"transient modulation"--that is, a modulation in which the new key is not established. Since this was a rather self-contradictory description, theorists in the early 1900s, such as Hugo Riemann
Hugo Riemann

 (who used the term "Zwischendominante" - "dominant inbetween"), searched for a better description of the phenomenon. One method of signifying these chords at the time (used by both Riemann and Ernst Kurth

) was by placing the chord symbol in parentheses, thereby indicating that the chord functions only in relation to the chord immediately following it - for example, (VII) V.

Wolfgang Amadeus Mozart

 Piano Sonata K. 283 in G major serves as one illustration of secondary dominants. Below, the harmony alone is first given, labeled both for the literal names of the chords and for their chord number in the key of G major.

It can be seen that this passage has three secondary dominants, each one followed (as expected) by the chord of which it is the dominant. The final four bars form a back-cycle, ending in a standard dominant-tonic cadence

, which concludes the phrase. The lines drawn below the diagram show each instance in which a dominant is followed by its corresponding tonic.

The harmony is distributed more subtly between the notes, and goes faster, in Mozart's original:

The secondary dominants here create a rapidly descending chromatic harmony, an effective lead-up to the tonic cadence at the end of the phrase. There are many similar passages in Mozart's music.

Use in jazz

In jazz harmony, a secondary dominant is any Dominant chord (major-minor 7th chord) which occurs on a weak beat and resolves downward by a perfect 5th. Thus, a chord is a secondary dominant when it is functioning as the dominant of some harmonic element other than the key's tonic, and promptly resolves to that element. This is slightly different from the traditional use of the term, where a secondary dominant does not have to be a 7th chord, occur on a weak beat, or resolve downward. If a non-diatonic dominant chord is used on a strong beat, it is considered an extended dominant. If it doesn't resolve downward, it may be a borrowed chord
