Hopscotch

If you were to slowly thumb through the pages of a phone book (if you can even find a phone book), you’ll see the names gradually change, shifting one letter at a time until they become something completely different. If this same gradual modulation technique were applied to music, you’d end up with something like Hopscotch, where the keys gradually shift, one note at a time, until the end result is in a totally different harmonic area than where you started. If this all sounds too academic and cerebral, it may help to just think of it as a children’s game of hopscotch, with one instrument leaping over another until they arrive at a new destination.
