I meant more or less as in "Shady Grove" writing 1-7 instead of G-F or D-C--anyway--

The 1-6-2-5 chord progression is a common way of harmonizing a melody that runs back quite a ways, in fact, it(and many of the other popular chord changes) are found in those old ballads that we speak of in other threads--The Maid of Bedlam follows that chord progression (although some sticklers would say that it really moves to an Em with a B in the bass, at which time I'd say that that was really a Cmaj7, at which point someone would say that if I said that, why not say just say that the Am is really a C6, at which point someone else would jump in and say that it is a simple scale-wise decending line in the bass, at which point everyone would start posting insults in other threads and finally quit the group)--

Anyway, the point here is that the chord progression has been around since way before the "Four Seasons"(well, Frankie Valli and the... anyway, it probably wasn't used for very long before Vivaldi) but to also point out that one can stick an Em in between the C and the Am--Or if you want to play Jazz, an E7, so you'd have a C-E7-A7-D7-G7 progression to add to your "predictable" chord progression book--I gotta go!
