Aiva Try it →Watch full video →Gavin Leeper · Mar 2025

Demo summary

The user demonstrates the iterative process in AIVA by identifying a 'weird' chord in a generated Northern Lights track, manually fixing the chord, and regenerating the composition.

Step-by-step

Select a style such as 'Strings and Woodwinds' or 'Mystical Northern Lights'
Generate the initial track to review the chord progression and melody
Identify specific chords or timing issues in the editor
Manually remove or adjust the problematic chords
Click generate again to create a new version based on the corrected progression

Options

Arrange the instruments yourself instead of relying on the default presentation

Watch out for

The AI may continue to generate 'trash' melodies even after chord corrections

Tips

Use the generated track as a 'B+' foundation to write your own melody on top of
Focus on the chord progression and prompt stage as these most influence the musical material

Highlights

“pretty cool that I can just come back here fix that and now we're going to generate again”
