There’s a bug I found. Select E Lydian Result: shows key is from Bb major Expected: should be B major **Developer response:** Hi jacki, Glad you like the app. Good catch. Thank you. This will be fixed in the next update. Regards, John ### 5/5 — Great app *2020-06-25* It’s no frills, easy and quick. I wish it could play the tones bump I’m ok with it not doing so. It hard to find an app that teaches you mode that won’t change the core root note or make you dive into a menu to change mode. Thanks! You guys get it! **Developer response:** Thank You for your kind words. ## Frequently asked questions about Magic Circle of Fifths ### What is the Magic Circle of Fifths app?
