ChatGPT question and answering chord progressions

I analysed a question and answer progression with chat gpt

analyse chord progression : Csus4 | G | F | C | C | G | F | C  (question) | G | Dsus4 | C | G | G | Dsus4 | C | G (answer) 
 

The chord progression you've provided combines two sequences:

1. **Csus4 | G | F | C | C | G | F | C:** This sequence is 8 bars long and was analyzed in a previous response. It follows a tonic-subdominant-dominant pattern in the key of C major.

2. **G | Dsus4 | C | G | G | Dsus4 | C | G:** This sequence also spans 8 bars and starts with a G major chord. Let's analyze this part:

- **G:** This is a G major chord consisting of the notes G (root), B (third), and D (fifth).

- **Dsus4:** This is a suspended fourth chord built on the D root. It consists of the notes D (root), G (fourth), and A (fifth).

- **C:** This is a C major chord consisting of the notes C (root), E (third), and G (fifth).

- **G:** Another instance of the G major chord.

- **G:** Yet another instance of the G major chord.

- **Dsus4:** Another instance of the suspended fourth chord built on D.

- **C:** Another instance of the C major chord.

- **G:** Another instance of the G major chord.

In this second sequence, the chords also follow a tonic-subdominant-dominant pattern, similar to the first sequence.

Overall, when the two sequences are combined, the progression spans 16 bars and contains two instances of the tonic-subdominant-dominant pattern, each in a different key (C major and G major). This creates a sense of contrast and variation within the progression. The use of the Csus4 and Dsus4 chords introduces suspended chords, adding an element of tension and release. The resolution back to the tonic chords (C and G) in both sequences contributes to a satisfying and cyclical feel in the overall progression.

Just for fun, I had an early 8 bar progression of the orchestral example : construct -orch -a from Cognitone analyzed by Chatgpt  
analysis chord progression : Ebm | Gbmaj7 | B | Ddim | Ebm | Gbmaj7 | Ab(add9) | Bb7 |

In terms of harmonic analysis, here's an overview of the progression:

• The progression begins with an E flat minor chord (Ebm), establishing a minor tonality and a somewhat melancholic mood.
• It then moves to a G flat major 7th chord (Gbmaj7), introducing a major chord with added color tones.
• The B major chord (B) follows, creating a sense of brightness and departure from the previous chords.
• The progression then moves to a diminished chord (Ddim), which adds some dissonance and tension.
• The return to E flat minor (Ebm) brings a sense of resolution from the tension created by the diminished chord.
• The G flat major 7th chord (Gbmaj7) returns, creating continuity with the major chord tonality.
• The Ab(add9) chord adds another layer of color with the added ninth, enriching the progression.
• The progression concludes with a B flat dominant 7th chord (Bb7), which introduces a dominant chord that often leads to a resolution.

Overall, this progression features a mix of minor, major, diminished, and dominant chords, creating a sense of tension and release. The use of color tones in the Gbmaj7 and Ab(add9) chords adds depth to the progression's harmonic palette. The movement between different chord qualities contributes to the progression's dynamic and expressive character. 
 

Better is to ask for  
functional analyse chord progression : Ebm | Gbmaj7 | B | Ddim | Ebm | Gbmaj7 | Ab(add9) | Bb7 |  
Sure, let's analyze the functional harmony of the chord progression:

Ebm | Gbmaj7 | B | Ddim | Ebm | Gbmaj7 | Ab(add9) | Bb7

1. Ebm: This chord serves as the i chord in the key of E flat minor. It establishes the tonic, or home, chord.
2. Gbmaj7: This chord functions as the IIImaj7 chord. It adds a major color to the progression while introducing a sense of tension.
3. B: This chord functions as the V chord in the key of E flat minor. It has a dominant function and creates a strong pull toward the tonic chord.
4. Ddim: This chord functions as the viio chord. In the key of E flat minor, it's the diminished seventh chord built on the seventh scale degree. It introduces dissonance and acts as a passing chord leading to the next chord.
5. Ebm: Returning to the tonic chord reaffirms the key center.
6. Gbmaj7: Similar to the previous occurrence, this chord serves as the IIImaj7.
7. Ab(add9): This chord functions as the IVmaj9 chord. It introduces a major chord with an added ninth and contributes to the progression's tonal color.
8. Bb7: This chord functions as the V7 chord in the key of E flat minor. It has a strong dominant function, preparing the progression for a potential resolution.

In summary, the chord progression starts with a minor tonic chord (i), moves to a major chord with tension (IIImaj7), introduces a dominant chord (V), uses a diminished chord (viio) to create tension and movement, returns to the tonic chord (i), repeats the pattern with the major chord (IIImaj7), introduces a major chord with an added ninth (IVmaj9), and concludes with a dominant seventh chord (V7) that suggests a potential return to the tonic.

The progression plays with various harmonic functions, creating tension and release through the movement between tonic, dominant, and passing chords.
