I’m a musician and an economist. Sometimes you will find me playing acoustic folk rock and blues on guitar, harmonica and voice. And at other times I will be at work, where I apply my expertise in game theory to the computer modeling of social phenomena. I create simulations of people interacting – such as how people decide which way to vote on an issue such as a tax levy, or how people learn to sort objects given to them in an experiment. In these simulations, the user can set up characteristics of the environment, such as the number of people and their individual goals. After things are set up, users watch these interactions unfold. The simulation is a little story, and one need only tweak the inputs to see how the story changes.

As a musician, I was curious if a program that generates social stories could be refashioned to generate musical pieces. I wanted to build a music-generation engine that the listener could tweak in order to get a different piece each time. But not just any tune – a piece with some flow, some story. I like that tension between randomness and structure. On one hand, I want every song to vary in unpredictable ways; on the other hand, I want to create music and not structureless noise.

I created a basic story of predators and prey, whimsically naming the prey “Peters,” represented by rabbits, and the predators “Wolves.” My simulation depicts a plain in the savannah with a green oasis. The prey seek the oasis and the predators seek the prey. Each character has its own goals and the closer they are to achieving them, the happier they are. Both predators and prey want to have stomachs full of food, so naturally they want to be close to their target (be it prey or oasis). As they travel through the savannah, they learn what choices (directions of movement) make them happier, and use this experience to guide them.

So how does this story become music? To this question there are two answers: a technical one and an intuitive one. The intuitive answer is that in real life the story of predators and prey plays out geographically on the savannah, but musically this is a story that plays out over a sonic landscape. To elaborate, I abstracted the movement of the prey and predator on the geography of the plain into the musical geometry of a sonic landscape. The farther north an agent travels, the higher the pitch. And, the farther east an agent travels the longer the duration. In other words, as an agent travels to the northwest, she makes longer-lasting tones that are higher pitched. I also mapped happiness to volume, so that happy agents make louder tones. Finally, so that each agent would have a distinct voice as they traveled through this space, I chose different instruments for each agent.

In the video below I assigned the “church organ” sound to prey, and the “brass section” sound to predators.

Ultimately, there are some things that I like about this piece and others that I do not.

As a harmonica player, I improvise by creating and resolving tension. I think this piece does that well. The predator will pursue the prey into a quiet, low-pitch corner, creating a distant, rumbling sound – only to watch prey escape to the densely polyphonic northwest corner. There is an ebb and flow to this chase that I recognize from blues harmonica solos. In contrast to my experience as a harmonica player, however, I have found that some of the most compelling parts of the dynamics come from the layering of notes. The addition of notes yields a rich sonic texture, much like adding notes to a chord on an organ.

Unfortunately, for largely technical reasons, there is a lack of coherent rhythm and pacing. The programming platform (agent-based modeling software called NetLogo) is not designed to have the interface proceed in real-time. Basically, the overall speed of the piece can change as the processing load increases or decreases. I found that as agents learnt more about their surroundings (and more system resources are allocated to this “memory”), they became slower and slower. To fix this, I capped the size of their memory banks so that they would forget their oldest memories. The closest I have come to a rhythmic structure is by ordering the way that the agents play. This technique makes the piece have a call-and-response feel. If only the piece to had a coherent rhythm,  then I could imagine playing harmonica along with it.

One last comment on pitch: while an earlier version of this piece mapped each step in space to a semitone, things sounded too mechanical. Even though this was the easiest and most intuitive decision from a technical standpoint, it was aesthetically lacking, so I have now integrated traditional musical scales. The minor scale, in my opinion, is the most interesting as it makes the predator/prey dynamic sound appropriately foreboding.

You can play this piece yourself. Simply go to this link with Java enabled in your browser (recommended: Google Chrome). Pressing “Setup” then “Go” will create your own run of the piece. As it is running, you can adjust the slider above the graphic window to change the speed. Press “Go” again to stop the model, adjust any parameters you wish and press “Setup” and “Go” again to see how the piece changes. Here are some parameters to try: instA and instB to change the instruments associated with prey and predators; PlayEveryXSteps to change the pace of the piece (higher results in a slower paced piece); Num-PackAs and Num-PackBs changes the number of prey and predators; the vertical PeterVol and WolfVol adjust the overall volume of prey and predators.

In regards to my version of “Peter and the Wolf,” I have a number of things that I’m curious about.

First, how does this relate to what you think of as music? Do you like listening to it? Which elements do you like and which do you dislike? For example, what do you think about about the tension and rhythm – do you agree the first works and that the second could be improved? Would you listen to this for enjoyments’ sake, and what would it take for this to be more than a novelty? What do you think about the narrative that drives the piece? I chose the predator and prey narrative, admittedly, on a whim. Do you think there might be some other narrative or agent specific goals that might better drive this piece? Is there any metaphor that might better describe this piece? As a listener do you enjoy the experience of being able to customize and configure the piece? What would you like to have control over that is missing here? Would you like more interaction with the piece or less interaction?

Finally, and perhaps most importantly, what do you think of the premise? Can simple electronic agents (albeit ones which interact socially) aspire to create music? Is there something promising in this act of simulation? Is music-making necessarily a human activity and is this kind of work destined to be artificial and uncanny?

Thanks for listening. I look forward to your thoughts.

Can Hip Hop sound Islamic? And conversely, can one listen to Hip Hop in a Muslim way? What is at stake when a contemporary musical form like Hip hop (or rock or punk) is introduced into the catalogue of recognized Islamic music genres? What impact do these genres have on longstanding Islamic traditions of ethical listening? In the process of creating new genres of Islamic music, which have not been previously connected to Muslim music traditions, norms are negotiated, border zones are walked upon, limits explored. At the same time, these Islamic music practitioners, even those who push established artistic limits within the Islamic movement, nevertheless intend to uphold the initial ethical project.

Considering music as producing sensual pleasure or extreme emotional excitement, Muslim scholars throughout the ages have been concerned with its capacity to hinder the exercise of reason and self-mastery as well as with its promises for spiritual benefit.  Roughly, one can say that those who have opposed the practice of listening to music feared that music’s force arouses worldly passions which distract from the remembrance of God, whereas those who were favourable toward this practice – generally speaking these voices came from thinkers and practitioners of the Islamic mystical traditions  –highlighted music’s capacity to impel the believer to seek the spiritual world while simultaneously being attentive to its potential dangers. Among these two sides, there is a wide range of theological opinions, from those that prohibit any kind of musical singing (considering Qu’ran recitation and poetry recitation not in terms of the category music) as well as all musical instruments, to those that allow for singing and certain musical instruments (i.e. drums permitted, stroke instruments not), and those who allow for all the array of musical expressions (given that specific moral conditions are fulfilled).

If the evolution of Islamic music toward the incorporation of modern music traditions has already been controversial within many Islamic revival contexts, it is not exaggerated to claim that Hip hop, at least in the UK, is probably the most contested and is until now the most marginalized of the different music genres within the Islamic popular culture scene. Today’s British Muslim Hip Hop is an occasion to think about the struggles of young Muslims to incorporate a music tradition that epitomizes black music culture like no other contemporary genre into the larger frame of Islamic music in Britain, which has been largely associated with South Asian and Middle Eastern music traditions.

Muslim Hip Hop takes many different sonic and stylistic directions in the UK. Some artists advance their Muslim identity in the context of religion and others take a more political standpoint; many blend both to varying degrees.  What connects these diverse orientations is the critique of contemporary mainstream commercial Hip Hop. Many Muslim Hip Hop fans and artists see this music as little more than a glorification of materialism and sexism. The thriving Muslim Hip Hop scene in the UK, which is deeply influenced by Afro-Caribbean converts to Islam, clearly situates itself in continuity with early Hip Hop, as defined by black awareness, political messages, and an underlying Islamic identity. Their own engagement in Islamic Hip hop is thus seen as holding true to the ‘authentic’ Hip hop traditions by purifying a corrupted Hip hop and renewing and reconnecting it to its Islamic identity.

While Aki Nawaz’ FUN-DA-MENTAL were Muslim Hip Hop pioneers in early nineties British hip hop, it was notably Mecca 2 Medina which opened the doors for Muslim rappers in the reticent U.K. Muslim community. Currently, the Mozambique-born rapper Mohammed Yahya, the female rap duo Poetic Pilgrimage, the sisters from Pearls of Islam, Muslim Belal, and Rakin Niass (formerly of Mecca 2 Medina)  headline many urban Muslim cultural events in Britain. Lowkey and Jaja Soze are two well-established names in the UK Hip hop scene who are also present within the more subcultural Muslim scene.

The Islamic Hip hop scene in Great Britain struggles to find a way to bring the tradition of Hip Hop in line with Islamic traditions, molding it to conform to Islam’s ethics of listening and sonic practices. Hip Hop can be especially problematic (from a certain Islamic point of view) because danceability is usually one of its prime objectives. The sensual dance style instigated by Hip Hop is notably achieved through amplified bass and repetitive beats that often drown the vocals.  British Muslim Hip hop artists emphasize, however, that it is not so much the beats, but the spoken word art that connects Hip Hop to the sonic-linguistic practices of Islam’s pronounced oral tradition. A minority of rappers (for instance, Muslim Belal) adhere to a specific Islamic interpretation according to which music instruments are forbidden, and therefore use no instrumentals, only human voices as background music. But the large majority of Muslim artists, including those who are outspokenly religious, do use instrumentation. Yet, a fine line seems to exist where beats begin transmuting into “nightclub” sounds. While neither clearly defined, nor necessarily articulated by the artists themselves, Muslim artists nonetheless avoid this musical point of no return so as not to marginalize the spoken word. Jaja Soze’s “Just Like Me” is a good example of such sonic practice. Soze plans to do exclusively spoken word in the future.

.Notably, according many Muslim Hip Hop artists in the UK, Hip Hop invokes important similarities with forms of recited or sung poetry, practices which were so cherished in the early Islamic community. For all these artists, reconciling Islam with Hip hop means recentering the spoken art form by sonically emphasizing the voice and the words. Thus, Islamic Hip hop is stylistically related to spoken word poetry, which frequently critiques the camouflaging of Hip hop lyrics behind beats. The lyrical content is also reflective of an Islamic ethic, often weaving explicitly pious Islamic themes with politically and socially conscious lyrics. Racism, Islamophobia, Neo-Liberalism and Imperialism in the age of the Global War on Terror are constant themes, as are critiques of the gang violence faced by minority communities in England’s major cities and cultural practices connected to the countries of origins of Muslim immigrants. “Silence is Consent,” from Poetic Pilgrimage, a female Hip Hop and Spoken Word duo and one of the few Muslim female Hip Hop artists in the UK highlights such socially conscious lyrics.

.

Lowkey’s lyrics in “Terrorist?” are an especially strident  critique of the War on Terror:

.

Far from constituting a vital unit with the lyrics (as is otherwise commonly assumed for Hip hop), beats and musical instrumentation are often treated as dispensable in Muslim Hip Hop. Even the artists who use instrumentation regularly perform their pieces a cappella on events that do not allow music instruments; many artists even offer their CDs in two versions: one with and one without instrumentation. Also, many artists switch easily from spoken poetry to Hip hop (the same lyrics can be performed, depending on the demands, as a spoken word or a Hip hop/rap piece), as they consider spoken poetry to be an intrinsic part of the broader Hip hop culture.

Such considerations are in line with Islamic traditions of listening, with their strong concern for listening to the voice and to the word. Listening to voices and words that carry spiritual and sacred contents or disseminate more broadly positive messages is reasoned through the paradigmatic experience of Qur’an recitation. The invocation of “beautification” (translated literally from the Arabic term tajweed, which refers to Qur’an recitation) has become a common trope among the British Muslim Hip Hop artists I have interviewed in order to defend their artistic activity (whether pertaining to voice and instruments or only to their vocal skills). As in Quran recitation, “beautification” is employed here as a tool to facilitate the reception and to reinforce the affective impact of the word.  “Clarity” by Rakin Niass, who started rapping with the British rap group Cash Crew and is one of the founding members of Mecca 2 Medina, clearly promotes a moral life style.

.

Hip hop, if it wants to be considered  legitimate within an Islamic context, must enable an ethical listening. Charles Hirschkind’s The Ethical Soundscape (2006) argues that listening in Islamic traditions, is “not a spontaneous and passive receptivity but a particular kind of action itself, a listening that is a doing” (34). It represents a form of active listening that involves both the intellect and the senses, promoting a specific way of being in the world. Consequently, I consider contemporary genres like Muslim Hip Hop, however modernized it might sound, does still bear the imprint of earlier da’wa traditions, encouraging an  virtuous life for listeners, and cultivating necessary ethical and political sensibilities through the ear.

These new musical styles are not only reflective of new sensibilities and subjectivities, they are, as notes Jean-Luc Nancy in Listening (2007), productive of subjectivity. It is for this reasoning that one should not underestimate the significance of the evolving music genres within the Islamic revival movement. Listening carefully to them will therefore provide crucial keys for understanding the possibilities for the development of specific ethical projects within a global mass culture.
