Please give me some ideas for a jazzy but sombre chord progression.<|im_end|>
<|im_start|>assistant
To create a jazzy yet sombre chord progression, you could use the minor ii-V-I progression. This progression is often used in jazz and consists of a minor ii chord, a dominant V chord, and a minor i chord. You could also try using minor chords with a diminished 7th or half-diminished 7th added in, as this will create a darker, more mysterious sound. Additionally, you could try using a minor chord with a major 7th added in for a more bittersweet sound. Finally, you could experiment with adding some chromatic passing chords or tritone substitutions to your progression to further add to the sombre mood.<|im_end|>

I want to play this on a guitar. What are some good references for finger charts in various neck positions.<|im_end|>
<|im_start|>assistant
There are many resources available online for guitar chord charts in different neck positions. Here are a few that you may find useful:

Ultimate Guitar: This website has a comprehensive database of guitar chords, with finger charts for many different positions on the neck. You can search for specific chords or browse through their library to find ones that fit your needs.

Chordbook: This website offers a variety of chord charts, including ones for different neck positions. You can select the root note and chord type to see the finger positions for the chord in different positions on the neck.

Guitar Chalk: This website offers a range of chord charts, including ones for more advanced chord shapes in different positions on the neck. They also provide explanations of how to play each chord and tips for fingering.

Justin Guitar: This website offers a wide range of guitar lessons, including lessons on chord theory and chord progressions. They also provide chord charts for various chords in different neck positions.

Chordie: This website offers a comprehensive database of guitar chords, including finger charts for different positions on the neck. You can search for specific chords or browse through their library to find ones that fit your needs.

Remember, it's always a good idea to practice new chords slowly and carefully, paying attention to your finger placement and making adjustments as needed. Over time, with practice, your fingers will become more accustomed to the different positions and your playing will become more fluid.<|im_end|>

Write me a bass guitar part that would sound good under those cords. Suggest a time signature to enhance the sombre mood.<|im_end|>
<|im_start|>assistant
4/4 will work well if you want to emphasize strong downbeats, but since you're looking to enhance the sombre mood, try 6/8 time. The triplet beat will give you more notes between downbeats, which can make it sound either sombre or jazzy, depending on the tempo. Here's my suggested bass guitar tab to go with a slower 6/8 time signature:
```
