God only knows
After writing Translations from the Original I was aware of certain things.
Firstly that my 'Original' theme was limited to stepwise movements of
chords with no sense of passing modulation to other keys so I wondered
how a more organic and developed chord progression would sound.
Secondly I had opted for 4 note chords which had given me 43 translations
quite a lot so a piece based on 3 note chords was an obvious
next step.
Finally I had gone for a simple linear presentation of the translations
with no sense of reviewing or previewing ideas, and there had not been
any faster progression through chord types.
The technique used in 'God Only Knows' is the same as for Translations
from the Original. There are 19 distinct 3 note chords within equal
temperament. For traditional major and minor (which account for two of
these) I also gave translations with the roles of x & y reversed.
At this point I would have had 21 translations available. I reduced this
- for all but traditional major and minor triads I treated inversions
as equivalent to one another and this left me with 15 available
translations. It was a manageable number and it felt more in tune with
the proportions of the harmonic series (there was a greater significance
given to simpler ratios).
I divided these 15 translations into 4 groups with previews etc. in the
following way:
Group 1
Intro [preview of 15, 9, 14, 6, 8]
Theme [1 major]
Interlude [10, 9]
Theme continued [1]
Translation [2]
Group 2
Minor theme [3]
Minor theme but with x & y reversed [4]
Group 3
Translations [5, 6]
Major theme but with x & y reversed [7]
Translation [8]
Group 4
Translation [9]
Link [4]
Translations [10, 11]
Translations of opening riff [12, 13, 9, 4, 1, 2]
Translation [14]
Translation [15]
Link [9, 14, 6, 8]
Recap Theme [1]
Coda [10, 12, 11, 14, 15, 6, 13, 5, 2]
There are passages where chord types follow one another in quick succession
the opening, the end where translations are recalled floating over
a repeated chord change, and the passage in Group 4 based on the opening
riff of the song.
Two other things worth pointing out - firstly, I make a more conscious
use of different time signatures. For example, the minor version that
begins group 2 is in 5/4, and the recap of the theme is translated to
3/4 (heard in this extract) [this is achieved by the tune retaining
its ordinary rhythm but the duration of the underlying chords expanding
by 4/3].
Secondly, the shape of the original melody is often retained within the
scales arising from the new harmonies.
One final point I had no need of a computer programme. Once you
appreciate the process (that is, the link between linear and vertical
intervals in relation to the harmonic and inverse harmonic series) you
can work out the chord sequences in a more traditional musical way by
using inversion and transposition. A person learning these techniques
from an early age would probably become very fluent in spontaneous translation.
