Intervals helps you break out of repetition, understand what makes music work and discover what sets great writing apart.
Access a huge library of chord types, discover which ones are closest to the chord you are using, and shape them until you land on exactly the sonority your music needs.
Apply modal operations, harmonic substitutions, and other advanced ideas in a simple way to turn a basic progression into something with more direction, tension, and personality.
Intervals explores voicing combinations and ranks them by their intervals, so you can choose shapes that feel cleaner, tenser, or more open depending on what the music needs.
See a progression from a theoretical and musical point of view, understand its function, its modal context, and the logic between chords so you know why it works and where to take it next.
Improve the voice leading of an entire progression and transpose the sequence into other modal contexts to discover new versions without losing its musical logic.
Work on a harmonic map, compare alternatives, keep useful branches, and develop an idea until it becomes real material instead of getting lost in disconnected experiments.
