Why is it called a dominant 7th?

The name comes from the fact that the flat seventh occurs naturally in the scale built upon the root when it functions as the dominant (i.e., the fifth degree) of some major diatonic scale.

Why does a dominant chord have a flat 7?

Because you're forgetting about the major 7th chord, which is the 7th chord which fits in the scale of the root note of that chord. Dominant 7th fits in the scale that has the root of the given chord as the dominant (5th scale degree) of that scale.

What is the difference between a major 7th and a dominant 7th?

A major 7th chord is formed by playing the root (1st) + 3rd + 5th + 7th notes of a major scale. A dominant 7th is formed by simply lowering the 7th note a half step. As an example, Cmaj7 = C - E - G - B (7th note). Lower the 7th note a half step, from B to Bb, thus Dominant 7th = C - E - G - Bb.

Why is a dominant seventh chord so powerful?

This dominant seventh chord is useful to composers because it contains both a major triad and the interval of a tritone. The major triad confers a very "strong" sound. The tritone is created by the co-occurrence of the third degree and seventh degree (e.g., in the G⁷ chord, the interval between B and F is a tritone).

Why is it called a diminished seventh?

Jean-Philippe Rameau explained the diminished seventh chord as a dominant seventh chord whose supposed fundamental bass is borrowed from the sixth degree in minor, raised a semitone producing a stack of minor thirds.

What Are Dominant 7th Chords? Guitar Theory Lesson

What is dominant seventh chords theory?

A dominant seventh chord naturally contains a tritone between its third scale degree and its flat seventh scale degree. For instance, an E7 (which is the dominant chord in both the A major key and the A minor key) has a tritone interval between its third (G♯) and its flat seventh (D).

What does the 7 mean in a C7 chord?

In chord symbols, "7" means minor 7th and "maj7" means major 7th. C7 = C major - minor 7th or C dominant 7th = C E G Bb. You build this chord by adding a minor 7th to a C major triad. Cmaj7 = C major - major 7th = C E G B.

What does dominant 5th mean?

dominant, in music, the fifth tone or degree of a diatonic scale (i.e., any of the major or minor scales of the tonal harmonic system), or the triad built upon this degree. In the key of C, for example, the dominant degree is the note G; the dominant triad is formed by the notes G–B–D in the key of C major or C minor.

A seventh chord is built by adding an extra note to a triad which is an interval of a 7th above the root note. e.g. If you build a triad on C you will use the notes (C-E-G). If you add a another note a 7th above C then you will have C-E-G-B. You have just created a basic seventh chord.

What is the difference between a dominant 7th and a diminished 7th?

Referring to the dominant 7th chord itself, the 3rd rises by a semitone and the 7th falls by a semitone when we move from dominant 7th to tonic. This is an example of semitonal pull. A diminished 7th is a chord built upon consecutive minor 3rds, and tends to be used to create tension in a phrase.
