The Modern Improviser

Kairos

Chester Harlan — Mon, 20 Jul 2026 09:02:25 GMT

The ancient Greeks had a word that every improviser should know: kairos. Unlike chronos, which expresses a chronological or measurable time, kairos underline the right moment. The instant in which an action assumes significance because it is performed at precisely the perfect time. The concept appears as early as Homer, where kairos refers to the critical point in battle, the precise opening where a weapon should strike. During the fifth and fourth centuries BCE, the Sophists, particularly Gorgias and Isocrates, transformed kairos into one of the foundations of rhetoric, arguing that persuasive speech depends not only on what is said but on when it is said. Aristotle extended this idea in both the Rhetoric and the Nicomachean Ethics, where successful action is inseparable from the ability to identify the most appropriate action in a given context

This notion resonates deeply with jazz improvisation. Great improvisers are not simply masters of harmony, scales, or vocabulary; they posses…

The Magic of The Köln Concert

Chester Harlan — Sun, 19 Jul 2026 13:47:33 GMT

On 24 January 1975, Keith Jarrett walked onto the stage of the Cologne Opera House (Oper Köln) and played one of the most celebrated solo piano concerts ever recorded.

The album that came from that night, The Köln Concert, is often described as a landmark in jazz. But it is more than a jazz record. It is a document of concentration, risk, endurance, and the strange way a limitation can shape a creative decision.

Jarrett, born in 1945, was only twenty‑nine years old. The concert, organized by the young German promoter Vera Brandes, began at around 11:30 in the evening, after an opera performance had ended in the same hall. The 1,300‑seat hall was sold out, and the audience knew they were coming to a completely improvised solo performance.

There was also a major problem: Jarrett was given the wrong piano.

He had expected a large Bösendorfer Imperial concert grand, but a smaller Bösendorfer baby grand used for rehearsals had been prepared instead. Its upper register was weak, its bass lacked…

How To Listen to Jazz: a 10-Step Guide

Chester Harlan — Tue, 14 Jul 2026 18:02:37 GMT

I was putting some order into a few old boxes recently and came across a printed-out copy of this article. It's "How To Listen to Jazz: a 10-Step Guide" by Luke Gillespie, originally published in DownBeat back in September 2019. I don't know how long it had been sitting there, but I read through it again and found it genuinely interesting, so I decided to transcribe it in full and share it here.

The Story of the Peacock Bird

Chester Harlan — Sun, 12 Jul 2026 20:07:43 GMT

This is a traditional folk tale from the oral cultures of southern Italy. It was recorded from a storyteller, Luigi Nigro, in Rossano, Calabria, in one documented version from 2006 and exists in many regional variations across the country. Professor Antonello Ricci, a professor of demo-ethno-anthropological studies in the Department of History, Anthropology, Religions, Art and Performing Arts (SARAS) at Sapienza University of Rome, collected and transcribed the tale through fieldwork and included it in his book Il secondo senso: per un’antropologia dell’ascolto(“The Second Sense: Towards an Anthropology of Listening”), published by Franco Angeli in its “Antropologia culturale e sociale” series. The tale appears in the section “Poetiche dell’ascolto” (“Poetics of Listening”), in the chapter originally titled “La storia dell’uccello pavone.”

Il suono come ordine simbolico

Chester Harlan — Sat, 11 Jul 2026 08:54:18 GMT

Ogni società ha i propri rituali. Spesso li pensiamo come modi per ricordare il passato, esprimere la fede o preservare la tradizione. Ma i rituali fanno anche qualcosa di più fondamentale: ricostruiscono il mondo in cui viviamo.

Gli antropologi hanno da tempo sottolineato che i rituali non sono semplici performance simboliche. Essi ripristinano l’ordine nei momenti in cui la vita diventa incerta. Questa idea era centrale nel lavoro di Ernesto de Martino, che descrisse il rito come una risposta a ciò che chiamava crisi della presenza, quei momenti in cui gli individui, o intere comunità, rischiano di perdere il proprio senso di orientamento nel mondo. Il rito non elimina il pericolo: restituisce la capacità di abitare la realtà.

Il suono svolge un ruolo notevole in questo processo.

Si pensi ai giorni tra il Venerdì Santo e la Pasqua. In molte tradizioni cattoliche, le campane delle chiese tacciono. Poiché le campane sono intese come la “voce” della Chiesa, il loro silenzio segna una sosp…

When Sound Rebuilds a Community

Chester Harlan — Sat, 11 Jul 2026 06:46:22 GMT

Every society has rituals. We often think of them as ways of remembering the past, expressing faith, or preserving tradition. But rituals also do something more fundamental: they rebuild the world we live in.

Anthropologists have long underlined the fact that rituals are not simply symbolic performances. They restore order at moments when life becomes uncertain. This idea was central to the work of Ernesto de Martino, who described ritual as a response to what he called the crisis of presence, those moments when individuals or entire communities risk losing their sense of orientation in the world. Ritual does not remove danger; it restores the capacity to inhabit reality.

Sound plays a remarkable role in this process.

Consider the days between Good Friday and Easter. Across many Catholic traditions, church bells fall silent. Since the bells are understood as the “voice” of the Church, their silence marks a temporary suspension of ordinary time. In many places they are replaced by wooden …

Listening Against the Eye

Chester Harlan — Fri, 10 Jul 2026 17:08:42 GMT

In Western thought, to know something has long meant to see it. We say “I see” when we mean “I understand,” and the metaphor is not incidental. Philosophy, science, and art have each been built on the model of perspective: a fixed vantage point from which the world can be surveyed, measured, and held at a manageable distance. This is the legacy of what scholars call oculocentrism, the quiet assumption that sight is the sense best suited to truth.

But vision is not a neutral instrument. It is the sense of separation.

The Architecture of Distance

To see something is to stand apart from it. Vision lets us classify, quantify, and study the world as an object before us rather than a medium we inhabit. The linear perspective that Renaissance painters formalized and the detached observer that the scientific method presupposes both rest on the same premise: that knowing requires distance, that the knower must remain outside what is known.

This has consequences beyond epistemology. A worldview org…

Listening to the World: Anthropology of Sound and Musical Improvisation

Chester Harlan — Sat, 04 Jul 2026 16:04:32 GMT

The anthropology of listening, or anthropology of sound, is a field within cultural anthropology that treats sound as a fundamental element in the construction of human experience.

It shares much with ethnomusicology, though its scope reaches beyond music toward the entire sonic environment, understood as something that shapes interaction, behaviour and the ways people are giving meaning to the world.

Western societies have tended to privilege vision as the primary path to knowledge. Reality is commonly imagined as something visualised, with the other senses relegated to a secondary role. But this hierarchy is definitively an historical and cultural construction. Many other cultures perceive and interpret reality primarily through listening. Even spiritual experience and relationships with invisible or transcendent realities are often mediated through sound before they are perceived through sight.

The American anthropologist Steven Feld introduced the term acoustemology, joining acousti…

Motor intentionality

Chester Harlan — Thu, 02 Jul 2026 07:00:48 GMT

Maurice Merleau-Ponty’s concept of motor intentionality provides an interesting philosophical framework for understanding expert improvisation. In Phenomenology of Perception (1945), he argues that skilled action is not the execution of a previously calculated mental plan. Rather, perception and movement form a single embodied process through which the body is already directed toward meaningful possibilities in the environment.

Maurice Merleau-Ponty

Rejecting both Cartesian dualism and the view that action is merely a chain of mechanical reflexes, Merleau-Ponty introduces le corps propre (the lived body) as the primary subject of perception. The body is not simply an object that the mind controls; it is the medium through which the world becomes immediately intelligible. As he famously writes, “The body is our general medium for having a world.” (Merleau-Ponty, Phenomenology of Perception, Part I, Chapter 3).

“Motor intentionality” describes this pre-reflective bodily orientation toward …

Never Play Alone

Chester Harlan — Wed, 01 Jul 2026 10:27:17 GMT

Some years ago, I came across Keith Ferrazzi’s book Never Eat Alone. Its central idea is simple: meaningful relationships are one of the greatest drivers of success. Musicians, however, have an even more compelling version of that principle.

We don’t just eat together. We play together.

Or at least we should. If I were to borrow Ferrazzi’s title for jazz, I’d call it Never Play Alone.

I immediately think back to my Berklee years in Boston. Many nights were spent with friends listening to CDs or tapes, one after another, stopping every few minutes to replay a solo, debate a harmonic choice, marvel at a phrase, and then move on to the next recording. We weren’t simply listening to music. We were learning together, feeding each other’s curiosity, and experiencing a kind of collective excitement in front of the extraordinary artistry we were discovering. Looking back, I realize those nights shaped my musicianship as much as any classroom ever did.

Jazz history offers countless examples. Geo…

The Psychology of Musical Confidence

Chester Harlan — Tue, 30 Jun 2026 08:51:05 GMT

Most musicians assume that progress depends on talent, better practice routines, or more advanced theory. Those things matter. But research in music psychology points to another factor that is often overlooked: self-efficacy.

Psychologist Albert Bandura defined self-efficacy as our belief in our ability to succeed at a specific task. In music, that belief can become a self-fulfilling prophecy. Students who genuinely believe they can master a difficult solo, improvise over unfamiliar harmony, or perform under pressure are more likely to persist, practice effectively, and ultimately succeed.

Albert Bandura

Michael S. Zelenak’s research highlights four foundations of musical self-efficacy:

• Previous experiences of success.
• Watching people like us succeed.
• Encouragement from teachers and peers.
• Learning to manage performance anxiety rather than being controlled by it.

What I find particularly interesting is that self-efficacy isn’t built through empty praise. It grows from carefully design…

The Logic of the Bebop Scale

Chester Harlan — Mon, 29 Jun 2026 13:19:37 GMT

The bebop scale is often presented as just another scale to practice. In fact, it is better understood as a way of organizing melodic movement. By inserting a single chromatic passing tone into a seven-note diatonic scale, an eight-note structure is created in which chord tones naturally coincide with strong beats during continuous eighth-note lines.

The added chromatic note is not arbitrary. It functions as a passing tone and is typically placed on the upbeat rather than the downbeat, preserving the metric placement of the underlying chord tones. This simple adjustment allows the melodic line to flow continuously while maintaining a clear relationship between rhythm and harmony.

The same principle extends across the major, dominant, minor, and half-diminished bebop scales. Rather than representing four unrelated scales, they are variations of a common concept: using a carefully positioned chromatic passing tone to organize melodic syntax.

For this reason, bebop scales are not merely tec…

Constraint as Method

Chester Harlan — Sat, 27 Jun 2026 14:16:53 GMT

Hello everyone,

I made this new backing track in Logic around a simple idea. Over Am7 and Dm7, play A Aeolian. When the harmony moves to Cm7 and Fm7, switch to C Aeolian. The challenge is not changing scales. The challenge is making the listener feel that your melodic line remains continuous despite the modulation.

A good way to practice this is to impose a limitation. Play only eighth notes from beginning to end. By removing rhythmic variety, you’ll naturally pay more attention to melodic shape, voice leading, phrasing, and the relationship between the two tonal centers.

I have always found that limitations produce better results than unlimited freedom. A simple constraint often reveals weaknesses in our playing, but it also encourages clearer musical thinking. Try to build ideas that evolve naturally rather than relying on speed or rhythmic complexity.

Here’s the 7 minute track below. Enjoy!

A Sound Worth Keeping: B Harmonic Minor Over Gmaj7(♯9)

Chester Harlan — Fri, 26 Jun 2026 09:56:18 GMT

There are certain sounds that seem almost accidental at first. You discover them while exploring the piano or the guitar, not because theory suggested them, but because your ear paused for a moment and refused to move on. Some disappear after a few minutes of curiosity. Others remain with you for years.

One of those sounds appears when a Gmaj7 chord is “disturbed” by a single unexpected note: A♯.

Play a Gmaj7 and let its familiar brightness settle into the ear. Then introduce the A♯ above it. The chord does not cease to be G major. Its foundation remains stable, yet something unexpected enters the picture. The harmony suddenly feels less resolved, less transparent. It acquires a quiet tension, neither dramatic nor dissonant in the conventional sense, but undeniably altered. It is a sound that seems to question itself while remaining beautiful.

The source of that A♯ is B harmonic minor.

From a theoretical perspective, the relationship is remarkably simple. B harmonic minor contains the not…

What Backing Tracks Can’t Teach You

Chester Harlan — Wed, 24 Jun 2026 15:31:51 GMT

First of all, backing tracks are a remarkable invention. They allow improvisers to practice virtually any chord progression, tune, or musical concept quickly and efficiently. In addition to the thousands of backing tracks available online, one of the finest tools available today, arguably the finest, is iReal Pro, created by a former colleague from my Berklee years, the outstanding bassist Massimo Biolcati. iReal Pro offers an impressive range of features and serves both professional musicians and students exceptionally well. Advanced performers can organize entire sets of charts for live performances using a tablet or even a smartphone, while students can use it to practice jazz standards and countless other musical materials.

For this reason, today’s post is not an argument against backing tracks, nor against technology more generally. Digital tools can be extraordinary companions for musicians seeking to practice scales, arpeggios, tunes, improvisation, or ear training. There are ma…

Mozart's Forgotten Student

Chester Harlan — Mon, 22 Jun 2026 04:11:52 GMT

Discovery of a Previously Unknown Mozart Autograph Manuscript in the Music Department of the Bibliothèque nationale de France

To be broadcast on France Musique, 22 June

The Bibliothèque nationale de France (BnF) has identified a previously unknown manuscript by Wolfgang Amadeus Mozart, composed during his 1778 stay in Paris. The document takes the form of a forty-four-page notebook containing composition lessons given to Marie-Louise-Philippine de Bonnières de Guînes (1759–1795), an accomplished harpist and daughter of the Duke de Guînes. Located in February 2026 in the BnF’s Music Department, the notebook constitutes a valuable source for understanding Mozart’s pedagogical methods.

Gilles Pécout, President of the BnF, characterized the find as among the most significant of recent decades, noting its dual importance: it documents Mozart’s final stay in Paris and reveals the daily activity of the young composer as teacher, in dialogue with his student. He observed that the BnF’s Music Dep…

Lennie Tristano and the Discipline of Hearing

Chester Harlan — Sun, 21 Jun 2026 11:28:30 GMT

The thing that keeps pulling me back to Lennie Tristano is how little of his teaching seems to be about the piano.

Students who studied with him often describe the same exercise. Before they were allowed to play a Lester Young or Charlie Parker solo, they had to sing it. Not approximately. Not enough to recognize it. They had to know it well enough that the line existed in their voice before it existed in their hands.

I’ve been thinking about that recently because it points to a problem that never really goes away. As improvisers, we can learn things faster than we can hear them. Our fingers are often ahead of our ears. We can execute patterns, quote language, even sound convincing, while remaining strangely disconnected from the music itself. Tristano seemed determined to reverse that order. The metronome work followed the same logic. He would often have students practice with the click slowed down dramatically.

Instead of marking every beat, the metronome might represent only beats 2…

The Melody as Duration

Chester Harlan — Fri, 19 Jun 2026 07:21:30 GMT

Bergson, Duration, and the Melody

Henri Bergson spent much of his philosophical career arguing against a particular illusion: that time is made of instants, lined up like beads, each one separable from the next. In Time and Free Will (1889), his doctoral thesis, he called this “spatialized time”. The time of clocks and calculus, useful for measurement but false to experience. What we actually live, he argued, is durée, duration: not a row of points but a continuous flow in which past and present interpenetrate, each moment swelling into the next rather than standing apart from it.

I keep returning to this idea because I think music gives it away more honestly than almost anything else does. A melody is the clearest case I know of something that simply isn’t there in its parts. Take Pavane pour une infante défunte, isolate any single note from its phrase, and you’re left holding nothing — a pitch, a duration on paper, but not the thing itself. The melody’s identity isn’t distributed acro…

Joe Pass and the Single Individual

Chester Harlan — Fri, 19 Jun 2026 07:18:52 GMT

Kierkegaard’s category of the single individual

Solo jazz guitar asks something most jazz doesn’t: that one performer be entirely self-sufficient, with no rhythm section to lean on and no one to answer. Joe Pass, on the Virtuoso albums of the mid-1970s, made a career out of this condition; walking a bass line, comping chords, and shaping a melody simultaneously, all from six strings under one pair of hands.

Kierkegaard’s category of the single individual (den Enkelte) comes to mind, though probably not in the way he intended it. For Kierkegaard, becoming a self meant a kind of radical aloneness before God, a refusal to dissolve into “the crowd” or to let one’s identity be underwritten by the social. The single individual stands without the comfort of being carried by others. Solo guitar seems to demand something structurally similar, if considerably less metaphysically weighted: there’s no crowd to dissolve into, no rhythm section to outsource responsibility to. Pass has to be the bass…

Villa Medici and the Sound of Rome

Chester Harlan — Fri, 19 Jun 2026 07:00:04 GMT

Villa Medici and the Sound of Rome

A building mostly known for its gardens and its view down onto the Spanish Steps has, almost as an afterthought, been one of the more important addresses in nineteenth-century French music. Since 1803 Villa Medici has housed the French Academy in Rome, and at various points its halls held Berlioz, Debussy, the later Ravel — though “held” might overstate it. Berlioz, for one, complained. He found Rome dull compared to the noise in his own head, and the Prix de Rome residency that brought him there reads, in his letters, more like exile than reward. Whether that restlessness made its way into the music is harder to say than I’d like Harold in Italy gestures at the landscape, but gesture isn’t the same as influence, and I’m not certain the connection is more than folklore.

What the villa actually gave these composers is something I can sense more than prove: distance from Paris, from the conservatory’s eyes, from whatever each was trying to outrun. I don’…
