App Description

Circle of 5ths is essential for all kinds of music. It is absolutely important for musicians to have a basic understanding of how the perfect 5th and intervals work in music.

If the interval of 5th (P5) goes further up or down from the key of C# (7 sharps) and Cb (7 flats), then there are more keys to explore than 7 sharps and flats. 
Any musical note or key signature can be named differently. For example, note C can be named as B#, Dbb and so on. 

Similarly with the key signatures, Major keys with 11, 12, 13, 14 flats are not named as Abb, Dbb, Gbb, Cbb, but they are simply called G, C, F, Bb. 
Audibly, they sound the same, but spelt differently because are needs to satisfy or adjust a musical rule (or many other reasons) in the particular situation. 

This version has enharmonic key spellings that show all key signatures clearly and how each key is related and dependent each other. 
Understanding these enharmonic spellings is very important. 

This App unlocks complete enharmonic key signatures that help to give a deep understanding of the circle of fifths and other related issues.
