Dylan\u2019s lyrics invite us to return again and again, each listen revealing a new meaning or shade. The biopic A Complete Unknown (2024) renewed public interest, but my reasons for a deep dive were already both personal and technical. My research uses AI to trace cultural messages across networks, and I wanted to test whether the same tools could illuminate Dylan\u2019s work as well. Could machine analysis measure the qualities that make Dylan\u2019s songs resonate \u2013 how complexity arises, how new images mix with the familiar, how ambiguity threads through songs?<\/p>\n
So I fed Dylan\u2019s official discography from 1962 to 2012 into a large language model (LLM), building a network of the concepts and connections in his songs. The model combed through each lyric, extracting pairs of related ideas or images. For example, it might detect a relationship between \u2018wind\u2019 and \u2018answer\u2019 in \u2018Blowin\u2019 in the Wind\u2019 (1962), or between \u2018joker\u2019 and \u2018thief\u2019 in \u2018All Along the Watchtower\u2019 (1967). By assembling these relationships, we can construct a network of how Dylan\u2019s key words and motifs braid together across his songs.<\/p>\n
To build that network, I passed every Dylan song through an LLM, one song at a time. The model treated each notable concept it encountered (such as \u2018wind\u2019, \u2018answer\u2019, \u2018joker\u2019, \u2018thief\u2019 and so on) as a node (the individual entities or concepts that surface in the songs). Two nodes were connected by an edge, representing the relationship between them. For instance, the LLM drew an edge between wind and answer in the line \u2018The answer is blowin\u2019 in the wind.\u2019 Each edge was then categorised as literal or metaphorical, and its emotional tone tagged as positive, negative or neutral.<\/p>\n
Because the model processes every line uniformly, it lets us measure (not just claim) how often, where and with what emotional charge any two ideas co\u2011occur, something no human analysis or close read has ever done at scale. After more than 500 songs, the process yielded roughly 6,000 unique nodes connected by about 9,000 edges. The resulting bird\u2019s-eye map shows, for example, how a metaphor in \u2018A Hard Rain\u2019s a-Gonna Fall\u2019 (1963) resonates with a later allusion in \u2018Not Dark Yet\u2019 (1997), or how a single biblical name reappears, but may be connected to a different concept and in a different mood.<\/p>\n
Network\u2011science tools similar to those used in epidemiology or social\u2011media analysis are increasingly common in humanities labs, yet Dylan offers a rare test case of a single author whose output is vast, poetic and varied. Free of the limits of any one reader\u2019s memory, the technique provides an objective framework to trace shifts in tone, thematic recurrence and metaphorical density across the entire body of songs. Our goal is not to replace the act of close reading, but to offer a fresh vantage point, so that we can see each lyric both in its own right and as part of a richly connected tapestry we might otherwise overlook.<\/p>\n
To make this abstract idea more concrete, consider Dylan\u2019s \u2018Jokerman\u2019 (1983), one of his most celebrated 1980s tracks. Figure 1 below is a network diagram for the song. Each node appears as a pink circle whose size reflects how often that concept shows up in the lyric, while arrows mark edges, indicating connections between ideas. At the centre, the Jokerman himself connects to a vivid set of nodes: the prince, the preacherman, Sodom and Gomorrah, and Michelangelo.<\/p>\n

<\/p>\n
Figure 1. Example network diagram: nodes represent entities or abstract concepts; node size = frequency; edges (arrows) represent connections between nodes<\/p>\n
The diagram hints at the song\u2019s dazzling variety: \u2018Jokerman\u2019 reaches into images of a biblical \u2018fiery furnace\u2019, a loyal little dog, the Book of Leviticus, a lurking rifleman and preacherman, and countless other details. These findings validate the linkages that longtime Dylan fans have observed. Critics have often noted Dylan\u2019s knack for blending the biblical with the everyday, casually dropping an Old Testament reference into a song that also mentions modern riot gear and tropical birds.<\/p>\n
Across six decades, Dylan\u2019s writing grows more figurative, his metaphors crowding out the plainspoken<\/p>\n
Stepping back from this song-by-song snapshot, we built the same network for every track in Dylan\u2019s catalogue, and then merged all the nodes and edges, decade by decade. Each edge \u2013 like the one linking \u2018Jokerman\u2019 to Michelangelo \u2013 marks a moment when one lyrical idea points to another. We asked the LLM to label each connection as literal (eg, \u2018the pump don\u2019t work \u2019cause the vandals took the handles\u2019) or metaphorical (eg, \u2018a hard rain\u2019s a-gonna fall<\/a>\u2019).<\/p>\n Figure 2 below makes the changes across time unmistakable: Dylan\u2019s lyrics move from a near balance of literal and metaphorical expression in the 1960s, to a catalogue where metaphor steadily takes the lead. In the 1960s, about 60 per cent of edges are metaphorical and 40 per cent literal. By the 1980s, metaphor pushes past two-thirds. By the 2010s, it swells beyond 75 per cent, leaving literal connections at less than a quarter. The trend is clear: across six decades, Dylan\u2019s writing grows more figurative, his metaphors crowding out the plainspoken. Critics had long sensed that Dylan grew more oblique, but the AI lets us put a number on it: metaphor\u2019s share climbs 1\u20132 percentage points per album, a change too gradual for the naked eye to track.<\/p>\n Figure 2. Percentage of edges (connections between entities in Dylan\u2019s lyrics) that are metaphorical rises steadily; literal statements fall across six decades<\/p>\n Why does this matter? Metaphor is often where an artist\u2019s emotional truth comes out. Interestingly, I find that Dylan\u2019s metaphorical expressions tend to carry a more negative emotional tone on average than his literal statements. For example, when Dylan sings \u2018the emptiness is endless, cold as the clay\u2019, from \u2018Mississippi\u2019 (2001), or \u2018evening\u2019s empire has returned into sand\u2019, from \u2018Mr Tambourine Man\u2019 (1965), the LLM tags these as metaphorical edges, and finds that they convey melancholia or loss. By contrast, more literal lines like \u2018may God bless and keep you always\u2019, a line from \u2018Forever Young\u2019 (1974), tend to be more positive or neutral, according to the model.<\/p>\n Dylan\u2019s overall emotional expression shifts as his life and art unfold. His early 1960s protest songs often mix anger at injustice with an undercurrent of hope; take \u2018Blowin\u2019 in the Wind\u2019, which highlights pain (\u2018how many times must the cannonballs fly\u2019) but also insists the answer is still blowing in the wind. By the mid to late 1960s, Dylan\u2019s lyrics in songs like \u2018All Along the Watchtower\u2019 or \u2018Desolation Row\u2019 (1965) had grown more surreal and cynical, reflecting the tumults of the era with imagery of jokers and thieves and a world gone wrong. In the 1970s, after a retreat from political anthems, Dylan wrote more about personal relationships. The album Blood on the Tracks (1975) is bittersweet, soul-baring, and infused with metaphors of weather and water to describe heartbreak. Then came the born-again period around 1979-81, which takes on an urgent, sermon-like literalness about salvation and sin (though even these are couched in biblical metaphor). By the 1990s, Dylan\u2019s work turned darker and introspective, with mournful masterpieces like \u2018Not Dark Yet\u2019. The late 1990s see an uptick in concepts related to mortality and a prevalence of negative-sentiment words (dark, cold, end, etc), corresponding to Dylan\u2019s age and the reflective, sometimes bleak outlook of albums like Time Out of Mind (1997). And yet, true to Dylan\u2019s volatile nature, the 2000s also feature playful romps (he won an Oscar for the wry \u2018Things Have Changed\u2019 in 2000) and historical sagas (the 14-minute \u2018Tempest\u2019 in 2012 recounts the Titanic sinking in vivid detail).<\/p>\n Commentators often divide Dylan\u2019s career into distinct eras: the young folk troubadour of the early 1960s, the electric rock poet of the mid-1960s, the country crooner of the late 1960s, the introspective songwriter of the 1970s, the passionate gospel preacher around 1980, and the reflective sage from the 1990s onward.<\/p>\n Unlike the neat eras described by traditional criticism, the AI graphs below are driven by data: they emerge from 9,000 connections between concepts, not from my preconceptions. By tracking thematic patterns across these phases with the help of an LLM, we uncover how Dylan\u2019s changing concerns align with his age, experiences, and the broader cultural currents of his times.<\/p>\n The protest\/political theme surges dramatically in the 1960s<\/p>\n Ultimately, the model turns sentiment into timelines with peaks and troughs. The emotion in Dylan\u2019s music has always been dynamic, not static, and the LLM\u2019s sentiment analysis reflects that, showing rises and falls in average song sentiment that align with major chapters of Dylan\u2019s life and six-decade career (see Figure 3 below).<\/p>\n Figure 3. Evolution of themes in Dylan\u2019s lyrics across the years<\/p>\n In the mid-1960s, journalists were hailing Dylan as the voice of a generation. That reputation is borne out in the data: the protest\/political theme surges dramatically in that decade, driven by iconic songs such as \u2018Masters of War\u2019 (1963) and \u2018The Times They Are A-Changin\u2019\u2019 (1963). The theme of violence, unsurprisingly, tracks alongside the era\u2019s unrest. By the decade\u2019s end, however, Dylan\u2019s pivot to electric rock and his step back from overt commentary coincide with a sharp drop in protest imagery. In its place, themes of love\/romance and emotion rise to the fore, mirroring both Dylan\u2019s turn inward and a broader cultural shift from mass movements to personal reflection.<\/p>\n It helps enormously to see Dylan\u2019s body of work, and the networks they generate, decade by decade. The diagrams below show the 50 most prevalent nodes for each decade along with the edges between them. As you look through the diagrams, remember that node size reflects connectivity, and colours mark broad node types, from abstraction to individual people. The point is to compare changes over time. The 1960s network (see Figure 4 below) shows protest and reportage as the main hubs, with a surreal collage threaded through a few bridge concepts.<\/p>\n Figure 4. Top 50 concepts network, 1960s: the model shows two dominant clusters: a protest cluster (\u2018masters of war\u2019, \u2018Oxford town\u2019, named figures such as Hattie Carroll and William Zantzinger) and a surreal\u2011literary cluster (\u2018desolation row\u2019, Ophelia). A small set of bridges connect these worlds, such as \u2018death\u2019, \u2018highway\u2019, and the wind \u2192 answer hinge. This makes visible how reportage and myth are wired together in the early work rather than living in separate registers<\/p>\n Meanwhile, the 1970s, as diagrammed in Figure 5 below, see Dylan fully immersed in personal themes. The decline of explicitly political and violent imagery continues, coinciding with Dylan\u2019s retreat from the public eye into family life and personal reflection (he married Sara Lownds in 1965 and settled in Woodstock). Romantic, emotional themes peak during the mid-1970s, especially notable on the album Blood on the Tracks (1975), widely interpreted as being inspired by Dylan\u2019s marital strife, producing intimate classics such as \u2018Tangled Up in Blue\u2019 and \u2018Shelter from the Storm\u2019. Nature imagery also rises, reflecting Dylan\u2019s introspective turn and his increasing use of pastoral and environmental metaphors.<\/p>\n The centre shifted in the 1970s to second\u2011person address and intimate themes<\/p>\n In the late 1970s to early \u201980s, Dylan experiences a dramatic thematic reversal. Themes of protest and violence return prominently around 1980, aligned with political critiques such as \u2018Union Sundown\u2019 (1983) and \u2018Neighborhood Bully\u2019 (1983). Simultaneously, mythic\/biblical imagery sharply increases as Dylan undergoes his highly publicised evangelical Christian phase, marked by albums like Slow Train Coming (1979) and Saved (1980). During this period, movement and travel themes reach their lowest point, perhaps reflecting Dylan\u2019s inward, spiritual journey rather than outward wandering.<\/p>\n The shift from love and emotional introspection toward broader social and spiritual concerns defines this tumultuous period. Indeed, the centre shifted in the 1970s to second\u2011person address and intimate themes (see Figure 5 below). In the 1980s, explicitly religious vocabulary becomes central and linked directly to geopolitical language (see Figure 6 below).<\/p>\n Figure 5. Top 50 concepts network, 1970s: the centre of gravity shifts to second\u2011person address and private life. A single hub around \u2018you\u2019 pulls in love, life, truth, light, money, and named figures such as Sara; distinct story clusters (\u2018Hurricane\u2019, \u2018Idiot Wind\u2019, \u2018Jack of Hearts\u2019) hang off that hub. The topology quantifies the decade\u2019s turn inward: more edges converge on address and relationship terms than on public themes, a change that is easy to miss without a macroscope<\/p>\n Figure 6. Top 50 concepts network, 1980s: religious vocabulary becomes structurally central (Jesus, lord, covenant woman, resurrection, righteous king) and links directly to worldly nodes like licence to kill and neighbourhood bully, and to the metaphor\u2011rich \u2018Jokerman\u2019 cluster. The network shows not two vocabularies but one mesh. It also reveals that religious terms act as bridges rather than islands, connecting moral language to political critique with high betweenness<\/p>\n The 1990s see another thematic shift, this time marked by Dylan\u2019s return to the role of the wandering observer. Protest themes recede once more, while travel and nature imagery rebound. This revival is illustrated in songs like \u2018Tryin\u2019 to Get to Heaven\u2019 (1997) and \u2018Highlands\u2019 (1997) where movement, journeys and natural imagery are central. Romantic imagery remains subdued, continuing to decline from the emotional intensity of the 1970s. Songs about love reach their lowest ebb as Dylan\u2019s narratives increasingly take on a more detached, reflective stance, perhaps mirroring his personal stage of life and cultural introspection at the millennium\u2019s end.<\/p>\n By the 1990s, the network fragments into smaller clusters tied to memory and self\u2011scrutiny<\/p>\n Finally, from the 2000s up to 2012, Dylan enters a phase defined by reflection and emotional complexity. Love and romance imagery notably rise to the highest levels, indicative of a late-career openness to personal reflection and emotional candour, evident in albums like Modern Times (2006) and Together Through Life (2009). At the same time, mythic imagery along with themes like protest and violence fade, suggesting reduced engagement with external controversies or spiritual fervour. Movement and travel remain persistently high: Dylan never stopped moving, both figuratively and literally (he\u2019s famously toured relentlessly since the 1980s on his Never Ending Tour).<\/p>\n Notably, by the 1990s, the network fragments into smaller clusters tied to memory and self\u2011scrutiny (see Figure 7 below). In the 2000s, the centre loosens again into modular Americana, with fables and historical images informing the narrator\u2019s voice (see Figure 8 below).<\/p>\n Figure 7. Top 50 concepts network, 1990s: the network fragments into smaller modules tied to inward themes: self\u2011deception, uncertainty, ghost of our old love, temporal markers today\/yesterday, and long\u2011walk images from \u2018Highlands\u2019. The loss of a single address hub and the rise of time and memory nodes quantify the decade\u2019s introspective turn and help explain why the sentiment of metaphor edges skews darker here<\/p>\n Figure 8. Top 50 concepts network, 2000-12: the structure settles into modular Americana. Clusters such as Tweedle Dum and Tweedle Dee, high water, and a general narrator hub sit beside archetypes (thief, captain, poor boy) and philosophical tags (noble truth). The network shows a return to collage, but with looser centrality than the 1970s address hub, and tighter motifs than the 1960s sprawl, which is easy to miss without a consistent decade\u2011wide measure<\/p>\n One theme steadily rises over the entire course: time. Its persistent ascent through the decades aligns intuitively with Dylan\u2019s own ageing and increasing preoccupation with legacy, and the passage of years.<\/p>\n What\u2019s striking is how Dylan\u2019s thematic tides mirror both his life stages and wider cultural shifts: the Cold War and civil rights turmoil of the early 1960s, the inward turn to domestic and romantic subjects in the mid-1970s, the spike in evangelical imagery around 1980, and the reflective, legacy-minded tone of the 1990s.<\/p>\n Underlying all these patterns is that enduring quality of Dylan\u2019s art: reinvention. He never stays the same. The line \u2018a complete unknown\u2019 \u2013 taken from the song \u2018Like a Rolling Stone\u2019 (1965), and the title of the 2024 biopic \u2013 is a fitting epithet for an unpredictable artist like him. In mid-1965, the up-and-coming folk artist who defined protest music at Newport Folk Festival stunned folk purists by going on stage with an electric band. A few years later, just when many expected another rock record, he surprised fans again with Nashville Skyline (1969), a gentle country album. In the late 1970s, he turned from secular poet to born-again Christian, only to veer back toward rock, blues and flirtations with hip-hop in the late 1980s. Each transition drew howls from some fans and critics, yet Dylan always moved on.<\/p>\n In his essay<\/a> \u2018On Bob Dylan\u2019 (2022), the legal scholar Cass Sunstein describes this restless shape-shifting as \u2018dishabituation\u2019: the deliberate disruption of expectations that keeps an audience awake and alive to what comes next. Since unpredictable stimuli trigger dopamine release, this neurochemical payoff may explain why Dylan\u2019s wildest phases remain so addictive.<\/p>\n Sunstein points to Dylan\u2019s expressions of delight in the off-kilter, or as Dylan himself puts it, his \u2018songs about roses growing out of people\u2019s brains and lovers who are really geese and swans that turn into angels.\u2019 Dylan, Sunstein notes, mocks \u2018rote or routine\u2019, and refuses to clap dutifully at protest slogans. That irreverence, Sunstein argues, explains everything from Dylan\u2019s refusal to become a 1960s movement mascot to the rootless exhilaration of \u2018Like a Rolling Stone\u2019.<\/p>\n The data support this interpretation. Think of the network of nodes as a subway map of Dylan\u2019s mind: with Grand Central stations named Love, Time, God at the centre; and branch-line stops called Nightingale or Fiery Furnace on the fringe. In network theory, the bustle around each station (a node) is called its centrality: the more connections a node has to other nodes, the more \u2018central\u2019 it is.<\/p>\n Variance spikes in the 1980s, when Dylan was darting from gospel rock to folk revival to synth-tinged pop<\/p>\n Now imagine measuring how much a song wanders between its central ideas. If the imagery circles only a few familiar hubs, the variance is low. If it leaps unexpectedly between the common and the rare, the variance is high. That spread serves as a rough \u2018dishabituation index\u2019: high variance means Dylan jolts us with a mash-up of the familiar and the unexpected, while low variance means he\u2019s moving through well-worn territory. Similar measures of variation have even been used to capture<\/a> the element of surprise in jazz solos, suggesting a bridge between Dylan\u2019s lyrical experiments and musical improvisation.<\/p>\n Plotted decade by decade (see Figure 9 below), the index for variance spikes in the 1980s, precisely when Dylan was darting from gospel rock to folk revival to synth-tinged pop. After that, it drifts downward, pointing to the more unified voice that emerges on albums like Time Out of Mind (1997) and beyond. After 1997 it settles \u2013 not tame, but tempered \u2013 the improviser growing into his groove.<\/p>\n Figure 9. Dishabituation index over the years: the higher the index, the more Dylan is mixing core nodes (ones with high centrality) with peripheral ones<\/p>\n Quantifying unpredictability may sound paradoxical, but the result offers the first hard-number confirmation of something fans have long intuited: Dylan\u2019s appetite for surprise reached its wildest heights in the 1980s, then gradually settled into a seasoned but still restless maturity. Musicologists have long called the 1980s Dylan\u2019s most wayward decade; the dishabituation index is the first numeric proof.<\/p>\n Sceptics might ask: do we really need an AI to tell us that Dylan wrote protest songs in the 1960s, gospel songs in the 1980s, and introspective laments in the 1990s? At one level, no. But as the historians Jo\u202fGuldi and David Armitage argue in The History Manifesto (2017), quantitative evidence and visualisation let historians test received wisdom and engage public debate with arguments that circulate beyond the academy, helping to arbitrate between falsity, myth, and noise.<\/p>\n The value lies in the detail and the confirmation. The model can pinpoint exactly which biblical names surge in the gospel period, how often \u2018rain\u2019 recurs across six decades, or how train imagery rises again in Dylan\u2019s 21st-century records. It shows, for instance, that lines tagged love\/romance grow more ambivalent in their emotional tone with age, quantifying a shift from youthful idealism to mature complexity. These empirical signposts don\u2019t replace human interpretation; they spark new questions. Why did Dylan\u2019s metaphors multiply so sharply? Was it artistic strategy, the influence of age, or simply the culture of the MTV era pushing lyrics toward abstraction?<\/p>\n Dylan\u2019s personal turns often mirror broader cultural currents: his protest songs echo the civil rights era; the gospel phase aligns with a nationwide religious revival; his late-career meditations reflect a generation grappling with legacy. This observation, which we usually understand anecdotally, becomes clearer as we visualise lyrical trends over decades. Digital humanities scholars like Ted Underwood caution<\/a> that data never replace close reading, but can offer a \u2018macroscope\u2019, re-framing familiar works in surprising, illuminating ways.<\/p>\n![\"Graph](\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2025\/11\/picture-2.png\"\/)
