user: Please give me some ideas for a jazzy but sombre chord progression.

assistant: Sure, here's a jazzy but sombre chord progression you might try:

Am7b5 - D7b9 - Gm7 - C7b9 - Fm7 - Bb7#11 - Ebmaj7 - Edim7

Here's a breakdown of the chords and their functions:

. Am7b5: This is an A minor 7 flat 5 chord, also known as a half-diminished chord. It creates a tense and dissonant sound, which makes it great for sombre moods.
. D7b9: This is a D dominant 7 flat 9 chord, which has a similar dissonant and tense sound to the Am7b5. It leads naturally to the Gm7 chord.
. Gm7: This is a G minor 7 chord, which provides a sense of resolution after the tension of the previous chords. It also has a sombre quality to it.
. C7b9: This is a C dominant 7 flat 9 chord, which creates tension and sets up the Fm7 chord.
. Fm7: This is an F minor 7 chord, which has a dark and melancholy sound. It's a great choice for a sombre mood.
. Bb7#11: This is a B flat dominant 7 sharp 11 chord, which creates tension and sets up the next chord, Ebmaj7.
. Ebmaj7: This is an E flat major 7 chord, which provides a sense of resolution after the tension of the previous chords. It also has a jazzy quality to it.
. Edim7: This is an E diminished 7 chord, which adds a bit of dissonance and tension to the end of the progression.

Overall, this chord progression has a sense of tension and release, with some sombre and jazzy elements mixed in. You could try experimenting with different rhythms and tempos to further develop the mood and feel of the progression.
