Professor Phil Moriarty and YouTuber Dave Brown (
boyinaband) created a "math metal" song
based on the Gold Ratio (Phi).
Here's the track (with music video!):
Below, in his own words, is Phil's explanation of what they did:
BY PROFESSOR PHIL MORIARTY
(note timings are mapped to start of the song, not the YouTube videos)
Here are all the gory details for the musicians amongst you...
Guitar tuning: Bb F Bb Eb G C
(This is traditional “drop D” tuning, i.e. D A D G B E, dropped two tones in order to approximate the math metal/Djent sound without a seven string guitar.)
We stick almost exclusively to riffs derived from the Bb harmonic minor scale (although the chorus is based around the natural Bb minor scale).
I used Guitar Rig to record the riffs (both clean and effected) which I then sent to Dave who used his studio wizardry and musical acumen to arrange and structure the song.
This involved quite a number of e-mail exchanges to hone the structure of the song during which Dave had to rein in my old school metal tendencies on more than one occasion.
Riff-by-riff
0:00: We kick off with a clean picked piece which looks like this:
The digits of phi are “embedded” in the notes played on the 4th and 3rd strings.
I make use of octaves and finger picking to embellish the riff.
0:08: Dave comes in with sixteenth note “chugs” (on Bb) which are timed to match the digits of phi (as explained in the video).
00:16: All hell breaks loose. Same idea as for ‘chug’ pattern starting at 0:08, except this time matched by kick drums.
(All drum programming by Dave –
visit his website for tutorials on how he lays down those impressive drum tracks).
00:40: The riff for verse 1 is basically power chords given by the digits 161803398, as follows (where ^ represents a higher octave):
1 - Bb
6 - Gb
1 - Bb
8 - ^Bb
0 - ^Db
3 - Db
3 - Db
9 - ^C
8 - ^Bb
8 - ^Bb
00:55: The chorus is a similar idea but this time in Bb minor (not harmonic minor).
1 - Bb
6 - Gb
1 - Bb
8 - ^Bb
0 - [rest]
3 - Db
3 - Db
9 - ^C
8 - ^Bb
8 - ^Bb
7 - Ab
1:11: Here we switch to ‘encoding’ the [1 + sqrt (5)]/2 representation of phi in the riff.
It’s a much more old school metal riff and involves lots of use of the open sixth string (first note of the Bb harmonic minor scale) to incorporate ‘1’.
The digits of sqrt (5) are then encoded as shown in the tablature below.
I wanted to get a somewhat Mastodon-esque feel here so used lots of octaves (and slides into octaves).
I tried to down-pick as much as possible to ‘drive’ the riff . The ½ of (1+sqrt(5))/2 is built in as half-time on the drums.
1:27: I very much wanted to have a heavily Tool-influenced riff in the song. Tool are math metal pioneers and, as many of those who have watched the “Golden Ratio – Making a Math Metal Anthem” video have pointed out, their song Lateralus has lyrics which are based around the Fibonacci sequence. So, the following is my ‘homage’ to Tool...
The digits of phi are encoded in the notes on the sixth and fifth strings and I ‘pedal’ around Bb notes on the third, fourth, and fifth strings.
2:15: As explained by Dave in the video, his riff here is also derived from (1 + root 5 )/ 2.
Root 5 is embedded in the number of chugs again and the drums are half time.
The “1” is a sustained and ringing Bb note.
Lyrics
Irrational!
Real but uncountable
Non-transcendental!
At the root of the problem
Patterns will
Emerge from the equation
Golden Angle
Sprials out of control
Chorus:
The proportion is divine
You'll find your way
to Phi (to Phi) (to Phi)
The ratio defined
You can’t deny
it's Phi
The five-fold way
Forbidden symmetry
Crossing points define
Demonic geometry
--- Verse 1 is fairly self-explanatory. Verse 2 above is a little more obscure. It refers to the pentagram which, of course, is a key piece of metal ‘iconography’. The verse refers to five-fold symmetry which is directly linked to phi ---
Phi = root(1 + Phi = root(1 +Phi = root(1 +Phi = root(1 +...
--- This stems from the equation φ = sqrt (1 + φ) which, of course, is recursive – hence the looping lyric ---
