Questions about Chord Constructor.
The practical details behind the request, access and result.
Can Chord Constructor help me write a jazz progression?
Yes, it can help you build complex progressions by identifying the harmonic roles of your chords and suggesting different inversions to fit your melody.
How does Chord Constructor handle different types of voicings?
It can generate both closed and open voicings. This helps you choose the right note spacing for different instruments, like making a sound wider for strings.
Can I use Chord Constructor to check if my chords are in the right key?
Yes, you can ask your agent to determine the harmonic role of any chord within a specific key to ensure your progression follows the correct theory.
What kind of music notation does Chord Constructor understand?
It understands standard chord name strings. It can take a label like Cmaj7 and break it down into its roots, intervals, and other musical components.
Does Chord Constructor generate actual audio files?
No, it provides the musical data structure. It gives you the notes and voicings you need, which you can then use in your preferred music software.
Is Chord Constructor good for music theory students?
It's an excellent capability for students because it handles the heavy math of music theory, allowing you to focus on understanding how different chords function together.
What kind of chords can I parse?
You can parse over 80 types of chords, including major, minor, augmented, diminished, and extended chords like 7#11 or 9th chords.
How do I generate different musical textures?
Use the generate_voicings capability and specify either 'closed' or 'open' as the voicing style to arrange your notes.
Can this help with harmonic analysis?
Yes, the determine_harmonic_role capability identifies if a chord functions as Tonic, Subdominant, or Dominant within a specified key.
