If you have ever searched for music to study or relax to, you have almost certainly met lo-fi: mellow beats, warm chords, a soft crackle in the background, often paired with an illustration of someone working by a window at night. In little more than a decade it has gone from an internet niche to one of the most listened-to sounds in the world, playing in bedrooms, libraries, offices and cafés. Yet many people who listen to it every day would struggle to say exactly what it is. This guide answers the basic questions in one place: what the word means, where the genre comes from, what makes it sound the way it does, and how to start exploring it.
What does “lo-fi” mean?
Lo-fi is short for low fidelity, the opposite of hi-fi. For most of the twentieth century, fidelity described how faithfully a recording reproduced the original sound. A high-fidelity record was clean, detailed and full-range; a low-fidelity one was noisy, muffled or distorted, usually because it had been made with cheap equipment or in less than ideal conditions. The term was a technical judgement, and rarely a compliment.
Over time its meaning changed. Musicians recording at home on cassette machines, independent bands releasing rough demos, and listeners who loved the intimacy of those recordings began to treat the sound of modest equipment as a quality rather than a flaw. Today lo-fi describes music that chooses to sound warm, soft and slightly imperfect, even when it is made with professional tools. We explore that reversal in detail in our piece on how lo-fi became a sound.
Lo-fi as a genre
When people talk about “lo-fi music” today, they rarely mean any old low-fidelity recording. They usually mean a specific style, often called lo-fi hip-hop, together with its close relatives: instrumental tracks built on short loops, with relaxed drum patterns, jazz or soul harmony and a deliberately worn texture.
The genre grew out of sample-based hip-hop production. Producers built beats from fragments of old jazz and soul records, and those fragments carried the warmth and noise of the vinyl they came from. Two beatmakers are almost always cited as its forefathers: J Dilla in Detroit, whose loose, human drum programming changed how hip-hop grooves felt, and Nujabes in Tokyo, whose melancholic, jazz-based beats reached a global audience through the soundtrack of the anime series Samurai Champloo. In the 2010s, producers on platforms such as SoundCloud and YouTube took that template, made it softer and simpler, and YouTube live streams turned it into a daily habit for millions of people. For the full story, with sources, read our short history of jazz lo-fi.
What does lo-fi music sound like?
Lo-fi is easy to recognise within a few seconds, because most tracks share a handful of traits.
The tempo is relaxed: slow enough to feel unhurried, with a gentle pulse rather than a driving beat. The drums are soft and loose: muted kicks, rim clicks or brushes instead of loud snares, hi-hats with their brightness rolled off, and hits that fall slightly early or late instead of perfectly on the grid. That looseness, inherited from sample-based hip-hop, is what gives lo-fi its gentle sway.
The harmony is rich. Instead of the simple three-note chords of most pop, lo-fi borrows seventh and ninth chords from jazz, usually played on piano, electric piano or guitar. Those extra notes give each chord a wistful, warm or unresolved colour, which is why a two-chord loop can play for minutes without feeling empty. If you want to try them yourself, our guide to jazz chords for lo-fi spells out five progressions.
Then there is texture: vinyl crackle, tape hiss, gentle saturation, filters that roll off the high frequencies, a slight wobble in pitch. These effects soften the sound and push it slightly into the background. Finally, lo-fi usually has few or no vocals and is built on repetition: loops that evolve slowly, so the music never demands attention.
Is lo-fi the same as jazz?
No, though the two are closely related. Lo-fi borrows jazz harmony, instruments and swing, then simplifies them into loops and wraps them in a soft production style. Jazz is traditionally about improvisation, interplay and individual expression; lo-fi is about atmosphere and consistency. A jazz record invites you to listen closely to what each musician is doing. A lo-fi track invites you to let it play while you do something else.
Jazz lo-fi, the style at the heart of Mondolofi, is the branch that stays closest to jazz. It keeps the Rhodes and the upright bass, the brushed drums and the occasional muted trumpet, and focuses on the warm, late-night colour of the music rather than on virtuosity. Our guide to harmony, rhythm and space in jazz lo-fi explains how the two worlds meet, and our list of ten classic jazz albums shows where much of the sound comes from.
Why do people listen to lo-fi?
Above all, because it is easy to live with. Lo-fi is designed to sit in the background: it fills silence without competing for attention, which makes it a popular companion for studying, working, reading, cooking and winding down. It is predictable in the best sense. You can leave it on for hours without being jolted by a sudden drop, a loud chorus or a change of genre.
It also carries a strong mood. Lo-fi is gently nostalgic and cosy, associated with rainy windows, desk lamps and late evenings. Many listeners find that atmosphere comforting in itself, and for some the music has become a small ritual that marks the start of a study session or the end of a long day.
A word of caution on the many promises made online. Lo-fi will not, on its own, make anyone smarter, calmer or more productive, and claims that it “boosts focus” are usually marketing rather than evidence. What research does suggest is more modest and more useful: experiments on reading comprehension have found that music with lyrics tends to interfere more than instrumental music, which is one reason why instrumental genres such as lo-fi suit tasks involving words. We summarise that evidence, with references, in our article on studying with music.
The main types of lo-fi
Lo-fi has grown into a family of styles, each with its own tempo, colour and best use.
- Jazz lo-fi (jazzhop): jazz chords, Rhodes and piano, soft swung drums. Versatile and sophisticated.
- Chillhop: a little brighter and more groovy, with more melodic hooks.
- Ambient and sleep lo-fi: the beat recedes or disappears, leaving pads, slow piano and space.
- Lo-fi house: house rhythms with the same dusty texture; faster and more physical.
- Synthwave-tinged lo-fi: retro synthesisers and a neon, 1980s colour.
Our listener’s guide to the moods of lo-fi compares them side by side and suggests which suits which activity.
Common questions
Is lo-fi music made by AI?
Lo-fi existed long before AI music tools, and most of the genre’s history was built by human producers sampling and playing instruments. Today AI-generated music exists in many genres, lo-fi included, which has led platforms and listeners to pay more attention to who makes what. As with any music, the best guide is the artist’s or label’s own information.
Can I use lo-fi music in my videos or my business?
Not automatically. Lo-fi tracks are protected by copyright like any other music. Using them in videos, streams or public spaces requires the appropriate permission or licence, and personal streaming subscriptions do not cover public or commercial use. Our guide to background music for cafés and restaurants explains the basics for venues.
How do I make lo-fi myself?
All you need to start is a computer, free or inexpensive software and some patience. Our beginner’s workflow for jazz lo-fi walks through the process step by step.
Where to start listening
The easiest way to get to know the genre is to let it play. The Mondolofi live stream runs jazz lo-fi 24 hours a day, without talking or interruptions. If you prefer to choose by situation, our moods page suggests where to start depending on what you are doing: studying, working, relaxing, sleeping or enjoying an aperitivo. Give it a few sessions, at low volume, and you will quickly understand why so many people keep coming back to it.
