Circle of Fifths software is your musical companion. It assists you in improvising, composing or studying tonal structures underlying Western music. With the Circle of Fifths you can quickly determine harmonious relationships in your favorite songs as well as in your own compositions.

This is how it works: simply move the rotating wheel in the desired position and read out the key with the correct accidental. The dominant, sub dominant and the parallel minor are being displayed immediately.

And the best of all: You can play sounds by pressing the appropriate play buttons. You may choose between 3 built-in instruments: piano, violin and guitar.

Are you looking for a specific tonality? In that case, it is much easier to know the number of accidentals for each key. And this is exactly what you can find by using the Circle of Fifths.

There are errors. Could have been better. Key Signitures could be bigger.

5/5 stars

Honesty is the best policy

This app is exactly what it says it is. It provides the entire circle of fifths: every key, the accidentals for that key, and even will play (in three instrument selections) the note out loud (as well as the dominant, subdominant, and relative minor). If you know what you want..it's perfect. If you don't, and you don't even know what circle of fifths is then don't get upset if this app isn't what you expect.

4/5 stars

Great reference tool

Does what it says. This app simply makes portable the paper chart you already have kicking around somewhere...if only you could find it. Since it's digital, you could add some features to be more useful. Perhaps a major scale graph along the bottom highlighting the notes that are being viewed in the circle? Maybe a keyboard/fretboard showing the notes?Also, the audio is helpful to hear the intervals, but sometimes the sound is an octave higher than it needs to be. Great app.
