i saw a few charts where they didn't specify the key of the song but the note of the scale like so: 1 5 5 2 1 1. how would that work for the chromstic scale? it wouldn't, right?
usually what you'd do is use flats or shartps to show how it deviates from a major scale. so for example, 1, #2, 2, b3, 3, 4, #4, 5, #5, 6, b7, 7, 1 and of course for any of those flat/sharps you can choose between which way you want to do it (#4 or b5) depending on which one you prefer at that time
