Many professional musicians use number charts (aka Nashville Numbers) to perform their songs. Similar to the chord charts you may be familiar with, but instead chord names are replaced with numbers. Each number represents the scale degree of the chosen key signature.
So for instance, in the key of Cmajor, where C is the first degree, would be represented by the number 1. D by the number 2, E by the number 3, and so on.
One of the benefits to using number charts is that they can be transcribed into any key instantly. Whereas chord charts have to be re-written every time the key is changed.
You'll find this system quite indispensable if you work with one of 'those' singers who likes to pull a key change on you at the very last minute... or every two minutes (Providing you know your keys well enough).
Key Degrees has been created with number charts in mind. Displaying a random, yet playable 4 bar chord progression that can be generated over and over again with just a tap. The idea is for you to play through this progression on your instrument, in your own time, even repeating it if you like, then moving onto the next one. Once you feel comfortable with everything that your difficulty setting has thrown at you, step it up to the next one.
Varying levels of difficulty:
'Beginner' starts you off with just 3 keys (C,F and G Major) and progressions only containing the degrees 1,4 and 5.
As you work your way through the levels more degrees are added along with even more keys to test yourself on.
'Expert' Contains all major and relative minor keys.
You don't even need your instrument in front of you to practice. Although it is ideal to play along in order to familiarize yourself with how the chords relate to each other on your instrument, you can still practice your knowledge while sitting on the bus, or waiting for your train. Any time you have a spare minute.

Keyfur shows the Ionian(Major), Dorian, Phrygian, Lydian, Mixolydian, Aeolian(minor), and Locrian scales.
While showing you the scale, Keyfur capitalizes the major chords that can be played with the notes and lowercases the minor notes. The symbol for the diminished chord is º.
This is my first app. I tried to make it as simple and functional as possible. I tried to reduce the extra crap(no ads, no splash screen) because I know how frustrating it is to use some apps that slow you down from song writing.
Good luck and please leave your feedback in the comments.
