1. ## Music with "Pi" in Mind...

So, I am gonna try an experiment. I want to try to write a piece inspired by the irrational number, pi. I've seen some examples of this, but most take the 3.14 in base 10 and apply this to the notes.

I'd like to take this a step further and have pi perform three functions at once, defining the rhythm, the melody lines, and the chords simultaneously. To do this, I am taking the the base 10 version of pi and carrying it out to its one-hundredth decimal place (3.14159265358979323846264338327950288419716939937 51058209749445923078164062862089986280348253421170 679), but then I am taking that base 10 interpretation and converting it to other bases, as defined below:

Rhythm (Base 16): I am taking a basic 4-beat measure and subdividing it into 16 pieces. This requires base 16 as the number system. The base 10 version of pi above becomes: 3973EB87E5D708... Then, I'll assign note durations to each 16th-note fraction of the measure.

Melodic Movement (Base 12): The Western chromatic scale is a series of 12 notes. In base 12, 0 is the first note of the scale. Instead of progressing upwards chromatically, I am progressing using the Circle of Fifths (0=Scale Root, 1=Scale Dominant, etc.). As a side effect of this, I used the first digit in pi (the 3 before the decimal) to determine the key of the piece... In base 12, if 0=C, 1=G, 2=D, then 3=A. The piece is in the Key of A Major (or F# minor, perhaps...depends on how things start to sound when put together).

 Notes (Base 12) 1 4 3 8 9 0 8 8 A 7 B 7 3 A 6 4 4 8 4 8 8 0 4 4 8 0 0 8 8 8 8 8 8 0 0 8 0 0 4 8 8 0 4 4 0 4 4 8 0 4 4 0 4 0 4 4 0 4 0 0 4 8 8 4 0 0 0 8 8 4 4 8 0 4 0 8 0 0 4 8 4 0 0 0 0 8 0 0 8 8 4 8 8 4 E C# F# F C A- F F G A# D A# F# G D# C# C# F C# F F A- C# C# F A- A- F F F F F F A- A- F A- A- C# F F A- C# C# A- C# C# F A- C# C# A- C# A- C# C# A- C# A- A- C# F F C# A- A- A- F F C# C# F A- C# A- F A- A- C# F C# A- A- A- A- F A- A- F F C# F F C#

Harmony (Base 7): I have to admit that I arbitrarily determined that this piece should be predominantly tonal. In keeping with that, I then convert pi into Base 7 to determine the chord sequence using the 7 chords of a diatonic scale.

 Chords (Base 7) 5 6 5 1 5 6 6 6 4 2 2 2 4 1 5 6 2 3 1 5 5 4 0 6 4 3 4 3 3 6 6 5 3 0 1 6 2 6 0 5 6 6 1 2 1 2 4 5 4 1 5 1 4 4 0 6 0 5 2 3 0 1 1 6 4 6 2 2 1 0 4 1 4 5 0 0 4 6 5 3 3 5 6 3 3 1 1 4 3 1 2 4 6 2 2 6 0 2 6 5 2 2 2 1 3 0 6 3 0 4 1 4 1 6 2 4 0 4 0 F#m Gdim F#m Bm F#m Gdim Gdim Gdim E C#m C#m C#m E Bm F#m Gdim C#m D Bm F#m F#m E A Gdim E D E D D Gdim Gdim F#m D A Bm Gdim C#m Gdim A F#m Gdim Gdim Bm C#m Bm C#m E F#m E Bm F#m Bm E E A Gdim A F#m C#m D A Bm Bm Gdim E Gdim C#m C#m Bm A E Bm E F#m A A E Gdim F#m D D F#m Gdim D D Bm Bm E D Bm C#m E Gdim C#m C#m Gdim A C#m Gdim F#m C#m C#m C#m Bm D A Gdim D A E Bm E Bm Gdim C#m E A E A

So, am I crazy, or might this work?

I have no idea. I'd have to hear the music!

Looks like you certainly put a lot of thought into it! Whether or not it works would be subject to the subjectivity of the listener

Would love to hear it either way, though!

Depends what you mean by "might this work"... lol.

Best,

FossMaNo1 - Ever since you put this up, I've been wondering if you went ahead with the experiment?
