Lydian Dominant is pretty interesting! It's not quite uplifting, and it's not quite sad. But it IS good fun ;D If I did it right, it's actually simple to use. All you have to do is use a major scale, and then sharp the tonic note. You then begin the scale on the fifth scale degree... So C Major will have no sharps except for on C because it's the tonic note, and you start the scale on G, because G is the fifth scale degree. It would be G A B C# D E F G. The next one over, G Major, will have a sharp on F because it always does. Then you make G sharp because it's the tonic note, and begin the scale on D because it's the fifth scale degree. The scale becomes D E F# G# A B C D.
