Short answer

How can I use AI to check my chord progressions?

Your AI uses this MCP to parse chord strings and determine the exact harmonic role each chord plays in your chosen key. This ensures your progressions follow the musical logic you intend. You'll get a breakdown of functional roles for every chord provided.

The results you get

What the analysis provides

The AI processes your input to produce these specific outcomes.

FUNCTION

Defined harmonic roles

The AI identifies if a chord is a tonic, dominant, or subdominant. You get the specific function for every chord in the sequence.

CONSISTENCY

Key alignment check

The AI compares your chords against the target key. This shows you exactly where a chord might feel out of place.

STRUCTURE

Progression mapping

The AI maps out the movement between chords. You see the functional relationship between each step in the sequence.

HUMAN

Creative direction

The AI provides the data, but you decide if the tension or resolution fits your song. You make the final call on the musicality.

The workflow

What your AI does when you provide a chord sequence.

The AI handles the heavy lifting of music theory math so you can focus on composing.

  1. Read the chords

    The AI takes your text-based chord notation and converts it into a format it can process.

    parse_chord_string

  2. Assign functions

    The AI looks at each chord in the context of your specified key to find its role.

    determine_harmonic_role

  3. Verify the key

    The AI checks the relationship between the chords and the tonal center to ensure they belong.

    determine_harmonic_role

  4. Report findings

    The AI presents the functional analysis back to you in your chat interface.

FAQ

How this task behaves

  • 01

    Can the AI write the actual music for me?

    No. The AI only analyzes the harmonic roles of the chords you provide.

  • 02

    Does the AI change my original chord files?

    No. The AI only reads the chord strings you send in the chat to perform the analysis.

  • 03

    Can it analyze MIDI files?

    No. You must provide the chords as text strings for the AI to parse them.

  • 04

    Will it tell me if a chord is 'wrong'?

    It identifies if a chord deviates from the expected harmonic role in your chosen key, but you decide if that deviation is intentional.

  • 05

    Does it work with any musical key?

    Yes, as long as you specify the key in your prompt, the AI will determine the roles based on that key.
