<h2 id="Introduction">Introduction<a class="anchor-link" href="#Introduction">&#182;</a></h2><p>The goal of this notebook is to investigate and explore a method of time-stretching an existing audio track such that its rhythmic pulses become expanded or contracted along the Fibonacci sequence, using Euclidean rhythms as the basis for modification. For lack of a better term, let's call it <strong>Fibonacci stretch</strong>.</p>
<p>Inspiration for this came initially from Vijay Iyer's <a href="https://www.theguardian.com/music/2009/oct/15/fibonacci-golden-ratio">article on Fibonacci numbers and musical rhythm</a> as well as his trio's renditions of "Mystic Brew" and "Human Nature"; we'll use original version of the latter as an example throughout. We'll also touch upon Godfried Toussaint's work on <a href="http://cgm.cs.mcgill.ca/~godfried/publications/banff.pdf">Euclidean rhythms</a> and <a href="https://ics-web.sns.ornl.gov/timing/Rep-Rate%20Tech%20Note.pdf">Bjorklund's algorithm</a>, both of which are intimately related.</p>

<p>We can convert that into a sequence of <strong>bits</strong>, with each <code>1</code> representing an onset, and <code>0</code> representing a rest (similar to the way a sequencer works). Doing so yields this:</p>

<pre><code>[1 0 0 1 0 0 1 0]</code></pre>

<p>Note that both the music notation and the array are <strong>symbolic</strong> representations of the rhythm; the rhythm is abstracted so that there is no information about tempo, dynamics, timbre, or other musical information. All we have is the temporal relationship between each note in the sequence (as well as the base assumption that the notes are evenly spaced).</p>
<p>Let's hear (and visualize) an example of how this rhythm sounds in more concrete terms:</p>

<p>The Fibonacci sequence is closely linked to the <strong>golden ratio</strong> in many ways, including the fact that as we go up the sequence, the ratio between successive numbers gets closer and closer to the golden ratio. (If you're interested, Vijay Iyer's article <a href="https://www.theguardian.com/music/2009/oct/15/fibonacci-golden-ratio">Strength in numbers: How Fibonacci taught us how to swing </a> goes into this in more depth.)</p>
<p>Below is a plot of Fibonacci number ratios in <span style="color:red">red</span>, and the golden ratio as a constant in <span style="color:blue">blue</span>. You can see how the Fibonacci ratios converge to the golden ratio:</p>

<p>We might classify it as a <strong>Fibonacci rhythm</strong>, since every one of its pulse lengths is a Fibonacci number. If we wanted to <strong>expand</strong> that rhythm along the Fibonacci sequence, what would that look like?</p>
<p>An intuitive (and, as it turns out, musically satisfying) method would be to take every pulse length and simply replace it with the Fibonacci number that follows it. So in our example, the <code>3</code>s become <code>5</code>s, and the <code>2</code> becomes <code>3</code>.</p>

<p>Part of the beauty of working with rhythms in a symbolic fashion is that once we set things up, we can apply them to any existing audio track.</p>
<p>To properly map the relationship between a rhythmic sequence and an audio representation of a piece of music, we'll have to do some <strong>feature extraction</strong>, that is, teasing out specific attributes of the music by analyzing the audio signal.</p>
<p>Our goal is to create a musically meaningful relationship between our symbolic rhythmic data and the audio track we want to manipulate.</p>

(We can see that the tempo we've estimated differs by approximately 1BPM from the tempo that we've hard-coded from prior knowledge.

It's often the case that such automatic feature extraction tools and algorithms require a fair bit of fine-tuning, so we can improve our results by supplying some user-defined parameters, especially when using them out of the box like we are here. The variables `hop_length` and `tempo` are two such parameters in this case.

However, the more parameters we define manually, the less flexible our overall system becomes, so it's a tradeoff between accuracy and robustness.)

<p>The clicks for measures, pulses, and steps, overlap with each other at certain points. While you can hear this based on the fact that each click is at a different frequency, it can be hard to tell visually in the above figure.

<p>In the below figure, each measure is denoted by a large <span style="color:red">red</span> line, each pulse by a medium <span style="color:green">green</span> line, and each step by a small <span style="color:blue">blue</span> line.</p>

<p>Basically what we want to do is: for each pulse, get the audio chunk that maps to that pulse, and time-stretch it based on our calculated pulse ratios.</p>
<p>Below is an implementation of just that. It's a bit long, but that's mostly due to having to define several properties to do with rhythm and audio. The core idea, of individually stretching the pulses, remains the same:</p>

<p>(Note that while we're expanding our original rhythm along the Fibonacci sequence, this actually corresponds to a <em>contraction</em> when time-stretching. This is because we want to maintain the original tempo, so we're trying to fit more steps into the same timespan.)</p>

<p>This gets to the heart of the problem: when we time-stretch an entire pulse this way, we retain the original pulse's internal rhythm, essentially creating a polyrhythm in the target pulse's step (i.e. metrical) structure. Even though we're time-stretching each pulse, we don't hear a difference because <em>everything</em> within the pulse gets time-stretched by the same amount.</p>

<p>Listening to the rendered track in <a href="#4.5-Overlaying-target-rhythm-clicks">Part 4.5</a>, you can hear that aside from the beginning of each measure and pulse, the musical onsets in the modified track don't really line up with the target rhythm's clicks at all.

<p>The concept of Euclidean rhythms was first introduced by Godfried Toussaint in his 2004 paper <a href="http://cgm.cs.mcgill.ca/~godfried/publications/banff.pdf">The Euclidean Algorithm Generates Traditional Musical Rhythms</a>.</p>
<p>The algorithm for generating these rhythms is actually <strong>Bjorklund's algorithm</strong>, first described by E. Bjorklund in his 2003 paper <a href="https://ics-web.sns.ornl.gov/timing/Rep-Rate%20Tech%20Note.pdf">The Theory of Rep-Rate Pattern Generation in the SNS Timing System</a>, which deals with neutron accelerators in nuclear physics. Here we use Brian House's Python implementation of Bjorklund's algorithm; you can find the source code on <a href="https://github.com/brianhouse/bjorklund">GitHub</a>.</p>
<p>It turns out that our <em>tresillo</em> rhythm is an example of a Euclidean rhythm. We can generate it by plugging in the number of pulses and steps into Bjorklund's algorithm:</p>

<p>We can define both a custom target rhythm as well. In addition, neither <code>original_rhythm</code> nor <code>target_rhythm</code> have to be Fibonacci rhythms for the stretch algorithm to work (although with this implementation they do both have to have the same number of pulses).</p>
<p>Let's try that out with the same verse, going from an original rhythm with 8 steps (i.e. in 4/4 meter) to a target rhythm with 10 steps (i.e. in 5/4 meter):</p>

<h2 id="Part-7---Final-thoughts">Part 7 - Final thoughts<a class="anchor-link" href="#Part-7---Final-thoughts">&#182;</a></h2><p>This notebook started out as an answer to the question "What if we applied rhythmic expansion methods, based on the Fibonacci sequence, to actual audio tracks?"</p>
<p>It quickly grew into more and more, and we now have a working implementation of what I've dubbed Fibonacci stretch. Along the way I've come to a few conclusions that I'll go over:</p>
<h3 id="7.1-Fibonacci-stretch-as-a-creative-tool">7.1 Fibonacci stretch as a creative tool<a class="anchor-link" href="#7.1-Fibonacci-stretch-as-a-creative-tool">&#182;</a></h3><p>I think there's certainly a case to be made for Fibonacci stretch as an interesting and useful means of musical transformation; it's rooted in mathematical processes that have been shown to produce interesting artistic output, and <a href="#6.-Fibonacci-stretch-implementation-and-examples">Part 6</a> shows that Fibonacci itself can produce musically interesting results.</p>
<p>However, it has its limits as well, the main one being that the Fibonacci sequence grows at an exponential rate (with the rate actually being equal to the golden ratio). This means that above a certain <code>stretch_factor</code> value, Fibonacci stretch starts to feel somewhat impractical. For example, stretching <code>[1 0 0 1 0 0 1 0]</code> by a factor of 6 gives us a target rhythm with 144 steps, which isn't something we can easily perceive when crammed into the space of our original 8 steps.</p>
<p>One solution to this imperceptibility is to allow for the length of the modified measure to change as well. For example, a 2-second measure with 8 steps (4 steps/second) could be stretched into a 24-second measure with 144 steps (6 steps/second). The longer time span might yield more interesting results, but it might also obscure the relationship between the modified track and the original track.</p>
<h3 id="7.2-Rhythm-perception">7.2 Rhythm perception<a class="anchor-link" href="#7.2-Rhythm-perception">&#182;</a></h3><p>I gleaned a lot of insight from experimenting with different parameters. As shown in <a href="#2.2-Using-Fibonacci-numbers-to-manipulate-rhythms">Part 2.2</a>, the greater the <code>stretch_factor</code>, the closer we get to the golden ratio; with regards to rhythm perception, I found that this made the resulting rhythm sound more and more "natural", in an almost uncanny valley manner. This relates back to the limitations of Fibonacci stretch as a creative tool as well. Perhaps it would be worth examining the space of results that lie between stretch factors of 1 and 3, as those seem to be where the most musically interesting rhythmic shifts occur.</p>
<p>Similarly, plugging in different patterns for the <code>original_rhythm</code> and <code>target_rhythm</code> parameters yielded differing results, with some seeming more closely related to others. It's possible that there are some underlying rhythmic principles that more clearly explain how the relationship between the original and target rhythms affects how we perceive the stretched result.</p>
<p>In addition, the initially disappointing results of using naive time-stretch also indicate the importance of considering different perceptual levels of rhythm. We explored a solution using subdivision of pulses, but haven't dealt with perceptual levels of rhythm in a rigorous manner at all.</p>
<h3 id="7.3-Implementation-improvements">7.3 Implementation improvements<a class="anchor-link" href="#7.3-Implementation-improvements">&#182;</a></h3><p>The current implementation of Fibonacci stretch works well enough, but it also leaves a lot to be desired.</p>
<p>One of the biggest issues is the handling of tempo. Firstly, the built-in tempo detection almost never gives us the correct value, which is why for the examples we've had to pass in tempo values manually. Looking into alternate tempo detection methods could mitigate this. More importantly, however, the current implementation doesn't allow for variable tempo, which is a real problem with tracks that weren't recorded to a metronome. Simply using a dynamic tempo estimate (which <code>librosa.beat.tempo</code> is capable of) would go a long way into improving the quality of the modified tracks.</p>
<p>This implementation of Fibonacci stretch also doesn't work too well when <code>stretch_factor</code> &lt; 0. As with the "Chan Chan" example in <a href="#6.2-Examples:-customizing-stretch-factors">Part 6.2</a>, we don't get the results we expect. It might just be a quirk in the step length conversion in <code>euclidean_stretch()</code>, but it's also possible that an adidtional level of subdivision might be needed.</p>
<p>We might also want to explore using onset detection to improve the actual time-stretching process. Instead of choosing stretch regions purely based on where they fall in relation to the symbolic rhythm parameters, we could define regions in accordance with the sample indices of detected onsets as well, which could yield more natural sounding output.</p>
<h3 id="7.4-Future-directions">7.4 Future directions<a class="anchor-link" href="#7.4-Future-directions">&#182;</a></h3><p>There are a ton of avenues to explore further, some of which we've touched upon. For example, some of the most interesting results came from stretching a track so that the performance was converted from one meter to another (e.g. 6/8 to 5/4). Sometimes this occurred as a happy coincidence of Fibonacci stretch, but most of the time we had to pass in custom <code>original_rhythm</code> and <code>target_rhythm</code> parameters. I think it would be worthwhile to explore a version of the stretch method that could convert meter A to meter B without explicitly defining the rhythm patterns.</p>
<p>On a related note, exploring the possibilities of Euclidean rhythms, outside of their relationship to Fibonacci rhythms, could be worthwhile as well. In addition, we could allow each measure to be stretched using different parameters by passing in a list of arguments, each corresponding to a measure or group of measures. This would allow for more flexibility and creative freedom when using Fibonacci stretch.</p>
<p>Finally, I could see this stretch method being used in the context of a digital audio workstation (DAW), with both the symbolic meter data for a project and the raw audio signal for a track being modified. If embedded directly into a DAW, this would open up possibilities for rapid experimentation of rhythm in a music production setting.</p>
