Theory

Chordzy is built upon extensive research of music pedagogy.

Tracking

Chordzy keeps track of all your musical skills, including:

  • Every song you've played, including every measure
  • Every key signature you've encountered
  • Every melody

Over time, it learns what's hard and what's easy for you.

Spaced Repitition

How do you know when to practice what?

Chordzy uses Spaced Repitition, meaning it can make recommendations on what to study/review next. In other words, as you start to forget a certain skill/song, it will re-surface that content. This means you're always practicing the most relevant bits.
