An incredibly light piece of fluff that just popped out of nowhere and pootles about at random.
A straightforward recipe:
Quantum Foam sticks to the recipe.
The first couple of bars contain a simple riff. The third bar plays a tweaked version of the first bar and repeats it in the fourth bar. The fifth and sixth bars repeat the tweaked riff a fifth higher.
A tried and trusted formula.
Repetition gets boring after a while. Then it is time to vary the material in some way. One approach is to change key and the piece briefly modulates from A to B then back again to A.
The simplest route from A to B is via a chord that is shared between both keys, a pivot chord, as it is called. Although A and B are distant keys, they do share two pivot chords in common, E major and C#m. The progression, A-E-B, I-V-II, does the job well.
Except the piece takes a different route. It deliberately uses the unusual chord progression, E-Eb-F#, where the contrast between each pair of chords is extremely marked. There is no theoretical justification for this, but so what. If it sounds good, do it!
