Chord progressions

An audience, listening to a film score, rarely picks out every musical instrument, chord progression, or key shift. The listener simply feels moved. 

In this book, key progressions are distinct from chord progressions (which are discussed later in this chapter). Key progressions involve only changes from C to Eh to F and so on, while chord progressions involve changes from major to minor (among other harmonics). 

The pattern illustrated in Figure 3.26 is frequently referred to as a blues chord progression, but in reality it is only a key progression The chord structure remains a constant dominant seventh. ACID does not automatically allow you to select the type of chord used, hut if you throw in some loops (especially a good bass line) from a blues loop CD or bass lines with blues in the file name, you should get excellent results. The pattern works well with many jazz and pop hass lines as well, so go ahead and experiment. Again, the prevalence of this phrase (and even its inclusion in this book) may suggest that it is not the most creative blues pattern in the world, so feel free to funk it up.

Lasentec Partec 100 was found to give reasonably accurate data for the chord length distribution of sherical particles but the accuracy deteriorated progressively as the shape became more ellipsoidal [123],... 

You can feel this time-based complexity when you listen to music. Music propels your expectation forward, carrying your perception forward through the progression of chords. Music requires the flow of time. It is a conversation between your brain (shaped by your past) and the sounds you hear (in the present), taking place as you move into the future. Over history, in different cultures, music cycled from periods of simplicity to periods of complexity, and its progression is anything but Darwinian in nature. 

Chords and harmony are very complex topics that extend well beyond major and minor descriptions and well beyond the scope of this brief chapter. Although changing a loop from major to minor is impossible from within AQD, some simple mono-tonal loops can be used to create chords and these chords can be modified and progressed.
