Your PI pun in the title is very PI’nful! Nicely done.

My track for Pi Day, simply named “Pi”, is derived from the number Pi in several ways.

The first 109 digits are pulsed by the rhythm instruments (3 pulses for the digit 3, 9 pulses for the digit 9, etc.).

The first 10 digits of Pi are used to determine the pitches of the pulses and chords. The pitch is based on a chromatic scale of 10 semi-tones (0 through 9). The duration of each pitch is also determined by the first 10 digits of Pi. The higher the digit, the higher the pitch and the longer the duration. For example, the digit 9 has the highest pitch and longest duration, which lasts for 9 measures, the digit 3 is six semi-tones lower than 9 and only lasts for 3 measures, etc.

The result is a pleasant ambient track, with a slowly changing “melody” marking the first 10 digits over the full length of the track, created from the faster pulses of the first 109 digits.

The cover art is a photograph I created several years ago. How did they stuff all the digits of Pi into that fortune cookie?

Turning the assignment in early, for once, since I’m going to be away from home for a few days.

I took the first 64 digits of pi to produce the score.
I mapped the digits 1-5 to a Db pentatonic scale. Digits 6-0 were mapped an octave higher. This gave me an 8-bar phrase of 8th notes at a moderate tempo.

I created a second layer, mapping all digits to the same octave this time, and twice as slow. Then a third layer, four times as slow, and an octave lower. The first layer is played 4 times, the second one twice, and the third one only once. I added a three-bar intro playing a Gb, for the “3” before the decimal point, of course.

I selected three patches for Blamsoft’s Expanse synthesizer, EQ’d them to make sure they remained distinct, and assigned them to each layer. There’s a fair amount of reverb to give a sense of space. And that’s it!

For this challenge, §I made up the theme by using the first 30’ish digits of Pi (as many of us did!). They are played by a virtual Buchla at 314bpm.

The theme is doubled through different instances of more orchestral instruments with very different envelopes - and finally, everything is sprinkled with effects and other rhythmic​ elements.

Here’s mine!

Music to celebrate Pi day!

For this week’s Junto I made a track using 3.141592654 in several ways.

The main melody is in C major and literally plays Pi - 3rd note of scale, followed by first, followed by fourth etc. Added some harmonies and a bassline.

The main beat also uses Pi. 3 kicks, one snare, four hats in the first bar, 1 kick, 5 snares, 9 hats in the second. Added a bit of probability based hits for good measure and there you go!

All created on the Synthstrom Deluge.

Title: Octopuses on Saturn Singing the Pi Number for disquiet0376.
ID: TEFE-22-disquiet0376-2019-03-16-09-47-01
Author: Miquel Parera
Date: 2019-03-16

Duration: 00:09:00.19

Composition: It’s an improvisation with code (livecoding), using samples recorded during the week. All the algorithmic processes involved in numerical decisions have been replaced by the number pi.

hello all

I very much enjoyed this project
I chose chords based on Pi in the key of CMajor
up to about 30 or so places
so for example 3.14 turns into
chord 3 is Eminor
chord 1 is CMajor
chord 4 is Fmajor
and I played those chords on my newly gifted pedal organ
(featured in Pedal Putty disquiet371)
I then added drums, bass, and a melody on the electricity guitar
(which is a strange guitar like instrument I made last year)
I hope the tune makes you feel like eating pie
hence the title “Pie Time”

I am not exactly happy how it turned out compositionally but I liked the timbre that I achieved so I decided to share my entry nonetheless.

About the process:
I used Monte Carlo technique to approximate PI. The digits of this approximated value were treated as scale steps. These steps developed the short motif and in the style of Prolation Canon I added two higher melodies with the same notes as the original motif but played two and three times faster. I used TAL U-NO, VintageVerb and Reaktor ensambles (VHS degradation suite and grainstates FX) to transfer these notes into sound.

I love freestyle Latin disco from the 80s. That’s probably not surprising :slight_smile:

The hits that open the song and recur throughout are in Pi formation, i.e., three hits, one hit, four hits, etc.

Thanks for listening :+1:

I made this as thick as a pie. And it is round. There are some pi-like ratios in there, but I mostly played around them.

Wow, thats a really nice outcome :smiley:

The Soma Ether looks great too

A small metal ball (Pi!) rotates (circular, ergo Pi) on the inner walls of a gong to which a Korg CM-300 contact microphone is attached. Track one of two delivers this relatively realistically with reverb (lighter tones), a second track (darker tones) alienated by an DIY Clouds (all parameters controlled by an Doepfer Quad-Sinus-LFO, Pi again).

All these circular movements (especially my hand movement of the gong to make the ball circulating) are not perfect … so they are just an very rough Approximation Of Pi.

This piece is a generative modular patch triggered by a gate sequencer pattern of 3 steps on, 1 step off, 1 step on, 1 step off, 4 steps on, 1 step off, 1 step on, and so on to create a representation of Pi.

There is a lot of really great listening here this week. Nice challenge.

As I started to think on pi first thing came up to mind were Euclidean rhythms since they tend to be visualized in circular shapes. From then on it was a very natural step to take rational approximations of pi and then employ divided as Euclidean length and divisor as Euclidean division.

π = 3.141 592 653 5…
22 / 7 = 3.142 857 142 8…
355 / 113 = 3.141 592 920 3…
52163 / 16604 = 3.141 592 387 3…
86953 / 27678 = 3.141 592 600 6…
102928 / 32763 = 3.141 592 650 2…

What I wanted to go for was using these Euclidean rhythms play simultaneously and hoped the small differences past the decimal point would put these sounds out of sync.

102928…
86953…

Pamela’s New Workout at most allows you to enter numbers up to 32 so I started to look into Puredata patches and found some, and I don’t know why but 86953 / 27678 and 102928 / 32763 just seems to be stuck or not working when those values entered into the Pd patch. I didn’t have a way to convert that MIDI into my modular and since Pd is very new to me I got lost along the way.

At this point, I have used two 22 / 7 Euclidean rhythm, while Maths is offsetting one of them, this is how far I’ve gotten by Monday, but I will definitely come back to this idea later on, this made me see Euclidean rhythms in a new perspective and now I’m quite excited about them.

clicked give me a random sound on freesound 3 times, then another 3 times, and another 3 times. these 3 sounds i plugged into protoplasm.
(swedish singing/halloween ambient/kettle sounds)
all the levels i had at 3.14 where possible. recorded for 3 minutes 14 seconds. in audacity i applied lots of fx with values of 3.141, -3.141 31.41 etc finally paulstretched by 3.1 and time resolution of 3.141

I had some trouble with inspiration this week :upside_down_face:

I took some audio samples from this old Open University video which proves why the area of a circle is pi * r^2, some was PaulStretched for texture and little bits used as one shots and through a granular synth.

I used the Digitakt to add percussion (but nothing really related to Pi).

Tau day believers instead celebrate 2*pi (tau) day on June 28th and recognise this number as the proper “circle constant”. 31.4 bars in I gradually up the tempo from 98bpm to 196bpm which moves the song in a more dancey direction, but the shift is a bit messy.
