#tutorial : "Unlock the Secrets of Dominant Chords:
On all 12keys
Dominant chords are fundamental in music theory, adding tension and leading to resolution. They're built on the fifth scale degree of a key and are often used to create movement and stability. Let's go through each of the 12 keys:
1. **C Dominant (C7):**
- Notes: C, E, G, Bb
- Play the C major scale (C, D, E, F, G, A, B), then add Bb to form the C7 chord.
2. **C# Dominant (C#7):**
- Notes: C#, E#, G#, B
- Similar to C Dominant, but with sharps.
3. **D Dominant (D7):**
- Notes: D, F#, A, C
- Play the D major scale (D, E, F#, G, A, B, C#), then add C to form the D7 chord.
4. **Eb Dominant (Eb7):**
- Notes: Eb, G, Bb, Db
- Derived from the Eb major scale (Eb, F, G, Ab, Bb, C, D), then add Db to create the Eb7 chord.
5. **E Dominant (E7):**
- Notes: E, G#, B, D
- From the E major scale (E, F#, G#, A, B, C#, D#), add D to get the E7 chord.
6. **F Dominant (F7):**
- Notes: F, A, C, Eb
- Formed from the F major scale (F, G, A, Bb, C, D, E), adding Eb to make F7.
7. **F# Dominant (F#7):**
- Notes: F#, A#, C#, E
- Similar to F Dominant, but with sharps.
8. **G Dominant (G7):**
- Notes: G, B, D, F
- Derived from the G major scale (G, A, B, C, D, E, F#), then add F to create G7.
9. **Ab Dominant (Ab7):**
- Notes: Ab, C, Eb, Gb
- Built from the Ab major scale (Ab, Bb, C, Db, Eb, F, G), adding Gb to form the Ab7 chord.
10. **A Dominant (A7):**
- Notes: A, C#, E, G
- From the A major scale (A, B, C#, D, E, F#, G#), add G to get the A7 chord.
11. **Bb Dominant (Bb7):**
- Notes: Bb, D, F, Ab
- Created from the Bb major scale (Bb, C, D, Eb, F, G, A), adding Ab to form Bb7.
12. **B Dominant (B7):**
- Notes: B, D#, F#, A
- From the B major scale (B, C#, D#, E, F#, G#, A#), add A to create B7.

Dominant chords are versatile and can be used in various ways in chord substitution, passing chords, and chord progressions:
1. **Chord Substitution:**
- Replace a major chord with its dominant counterpart to add tension and create a stronger sense of resolution. For example, in a C major progression (C - F - G), you can substitute G with G7 to intensify the resolution back to C.
2. **Passing Chords:**
- Insert dominant chords between two diatonic chords to create smooth transitions. For instance, in a progression like C - Am - Dm - G7 - C, the G7 acts as a passing chord between Dm and C, enhancing the movement.
3. **Chord Progressions:**
- Use dominant chords to lead to the tonic chord (the chord built on the first scale degree). In a basic II-V-I progression (Dm7 - G7 - C), the G7 leads smoothly to C, creating a strong resolution.
4. **Secondary Dominants:**
- Introduce dominant chords that are not diatonic to the key to create tension and drive the progression. For example, in the key of C major, you can use A7 (the V chord of D, the ii chord in C) before resolving to Dm7 to add extra momentum.
5. **Extended Dominants:**
- Extend the dominant function by adding additional dominant chords before resolving. For example, in a jazz progression, you might see a series of dominant chords resolving to the tonic, like Dm7 - G7 - Cmaj7, followed by Em7 - A7 - Dmaj7.
6. **Modal Interchange:**
- Borrow dominant chords from parallel modes to add color and complexity. For instance, in a progression in C major, you might use G7#5 (borrowed from the parallel C harmonic minor) to create a unique sound.
These applications showcase the versatility of dominant chords in enhancing chord progressions, providing tension, and creating harmonic interest in music. Experimenting with these concepts can lead to creative and compelling musical arrangements.
