AI Music Theory Assistant for Composers

Let your AI agent handle harmonies, melodies, and arrangement checks, so you can focus on composing music instead of wrestling with theory details.

You spend hours in Sibelius, Finale, or Logic Pro, second-guessing chord choices and fixing voice leading. As a composer, you’re stuck referencing theory books and double-checking every motif, instead of actually writing music. The constant back-and-forth between your DAW and music notation apps drains your creative energy and slows your output.

An AI agent that helps composers create harmonies, melodies, and arrangements by applying music theory instantly to your projects.

What this replaces

Reviewing arrangements for errors in Sibelius
Handwriting motif variations in Finale
Cross-referencing theory books for each section
Editing voice leading transitions by ear in your DAW

The hidden cost

What this is really costing you

In the media and entertainment industry, composers and arrangers lose valuable time manually testing chord progressions, analyzing tonal structure, and rewriting motifs in notation software like Finale or Sibelius. Each revision means toggling between theory references, DAWs, and spreadsheets to check for errors or inconsistencies. This repetitive work not only delays project delivery but also saps creative momentum.
