There is no E#. Please change the diminished chord in the key of F# to F dim. Thanks.

A helpful App that gives a useful introduction to this aspect of music theory. Would be even better if it could also show the notes for major & minor pentatonic.

Great tool to learn the circle of fifths I’ve been told by high status producers that the circle of fifths is one of the most important things to know.

I really appreciate this app, but I would like to see other triad variants for each chord in the key as you tap on the chord, and maybe she’ll voicing for chords like 7s.

I have bad vision and have the text on my phone set to large. The app does not fit on my screen and gets cut off. Please fix.

I absolutely love this APP it’s incredible. For $1.49 you never need a book of paper to check the Key or Chord progression you want. Not only is it simple but you can listen before you even play your guitar to see if you like the progression. Thank you

There’s a book called ‘The Chord Wheel’ published by Hal Leonard that illustrates the same concept as this app. While it’s a good book to have on hand it has one important deficiency: it doesn’t show any fingerings or even the notes for the particular chords. For someone who isn’t very familiar with music theory, this can make it difficult to use the book properly, potentially requiring lots of cross referencing, googling, and general research into theory. This app solves that problem by presenting the circle of fifths/chord wheel side by side with sample fingerings for each chord. Simple, effective, and useful. Well worth the trivial cost of the app. Thanks to the developer for making this one.
