Writting down or playing major musical scales

It should be good and instructive fun.


Beginning with one of the most difficult on out planet which is D flat major (has so many black keys, for example Chatiots of Fire - Vangelis).
Actually playing Chariots of Fire will teach you the nice and uncommon sounding scale.


Then moving up a perfect fifth ie A flat major which has one fact note less.


Then moving up to Eb major which has one flat less...


Until one gets to the familiar C major scale (all natural notes or white keys.


Then moving on a perfect fifth again to G major which has one sharp.


Then moving to D major which has 2 sharps.


....


And finally arriving to C sharp major which has so many black notes and is the same as D flat major which is the sale where we started from and the circle of 5ths completes.


What do you notice happening to the pattern of flat or sharp notes while visiting each consecutive scale or key?


Also notice that all minor scales are relatives to the major one a minor 3rd above. For example A minor and C major had all notes natural or white keys.
