Description

You can play a standard perfectly well while reading it. Then someone calls it at a jam, the chart is gone, and you're not sure what happens in the bridge.

Know the Changes takes the safety net away gradually, so the changes move out of the chart and into your memory.

How it works
• Study the full chart
• Hide 25%, 50%, 75% or every chord
• Fill in the missing bars from a set of choices
• Check each section, then work through the whole form
• Switch keys to find out whether you know the harmony or just a sequence of chord names

Learn the version you actually play
Share a song or playlist from iReal Pro and open it directly in the app. Musicians disagree about changes, so you should be practicing your version. Or start right away with the built-in library of jazz standards.

Different every session
Hidden bars change each time, so you can't get by memorizing the pattern.

One job, done well
No melodies, licks or solos, and it isn't a jazz course. It does one thing: recall.

Family Sharing supported. No data collected.

Know the changes. Leave the chart behind.

Know the Changes is not affiliated with or endorsed by iReal Pro.
