This page presents a novelty topic.
It may contain ideas which are less likely to find practical applications in music, or numbers or structures that are arbitrary or exceedingly small, large, or complex. Novelty topics are often developed by a single person or a small group. As such, this page may also contain idiosyncratic terms, notation, or conceptual frameworks. |

Mode 3,746,579 of the harmonic series, also known as 3,746,579 afdo or the Over the Hedge scale [idiosyncratic term], is a 3,746,579-tone octave-repeating subset of the harmonic series.
It is so named because if "hedge" is read not as a word, but as a base 26 number (where Z=0, A=1, B=2...), then converted into base 10, it would become 3,746,579.
Thus, since all intervals of 3,746,579 afdo are something-over-3,746,579, they are all "over the hedge".
The prime factorisation of 3,746,579 is actually 17 x 73 x 3019. This makes the Over the Hedge scale surprisingly interesting from a primodality perspective, because it contains a very unique set of intervals: millions of available intervals but with no Over-2, -3, -5, -7, -11 or even -13 intervals to be found anywhere.
Of course, the sheer number of notes does make the Over the Hedge scale impractical to explore in practice, at least without some way to eliminate most of the intervals and focus on a chosen few (something like a few-hundred-note neji perhaps).
1241afdo would make much more sense for practical use, being 17 x 73.
Or perhaps something like 2431afdo, which is 11 x 13 x 17.
Still, if you're daring and crazy enough to venture over the hedge, well, no one can stop you. 3 million intervals are waiting for you.
Approaches
Any approach to the Over the Hedge scale has to start with drastically cutting down the number of intervals in play.
One way to do that is to make a neji scale using a large edo of interest.
Another way is to try a polymicrotonal approach. The Over the Hedge scale contains AFDOs 17, 73, 1241, 3019, 51323, and 220387 above its root, without rotating to any other mode. So, you could use multiple of those AFDOs at the same time, and you would technically be playing within the Over the Hedge scale.
You could even combine this with the neji approach: make nejis from each of those smaller AFDOs, and then have music in multiple nejis playing at the same time.
1241afdo and 3019afdo are probably the best combination to use for this polymicrotonal approach, because they have a large but still sane number of notes, they are within the same order of magnitude as each other, and their lowest common multiple is 3,746,579, so they uniquely identify the Over the Hedge scale.
Algorithmic music is also one possible approach to large scales like Over the Hedge. You could have an algorithm randomly explore the pitch space of the Over the Hedge scale. You could even use sensors to measure the electrical activity of a plant's leaves, and use that to control a modular synthesizer tuned to the Over the Hedge scale: you could have the Over the Hedge scale be played by an actual hedge.
