4GSE: S1-R1 S1-R2 S1-R3 S1-R4 S2-R1 S2-R2 S2-R3 S2-R4
Dear reader, I hope you find this interesting. There is much more to explore of course and I'm continuing on to outline how this might be applied. Melodies like these GS can be acquired and re-fashioned into endless melodies with a fresh approach and yet retain the essence or foundation of the original. Lots to look here but working a few of these changing patterns into tunes is surprising fun.
