EnglishHow Musicmap Organizes Popular Music Genres
Updated
Musicmap organizes popular music genres as a genealogy: a single interactive chart that arranges genres by time (roughly the 1880s to the 2020s) and draws lines of descent between parent genres and the subgenres that grew out of them. Instead of listing genres alphabetically or by popularity, it treats them like a family tree, so you can trace how, for example, blues and gospel feed into rhythm 'n' blues, and how that in turn branches into rock 'n' roll, soul, and other styles. This makes it useful if you want to understand relationships between genres, not just look up a single definition.
The two organizing axes
Musicmap's layout combines two dimensions at once:
- Time (horizontal): decades run along the map, from the 1880s through the 2020s. Older roots sit on one side, and newer offshoots appear as you move forward.
- Genealogy (vertical/structural): genres are positioned so that a parent genre sits "above" or "before" the subgenres derived from it, with connecting lines showing the derivation.
The result is a dynamic map rather than a static list. A genre's position tells you both when it emerged and what it came from.
Major genre families
The map groups individual genres into larger families, each of which then splits into subgenres. The broad categories visible in the map include:
| Family | Examples of subgenres shown |
|---|---|
| Blues | Rhythm 'n' blues, rock 'n' roll roots |
| Jazz | (feeds into rhythm music and later styles) |
| Gospel | Roots for soul and R&B |
| Country | Country, folk revivals |
| Jamaican | Reggae, ska, dub |
| Rap / Hip hop | Rap rock, funk metal crossovers |
| Rock | Punk, metal, alternative, indie, grunge |
| Electronic | House, techno, trance, drum 'n' bass, breakbeat |
| Pop | Pop & rock, contemporary pop |
| Metal | Heavy metal, metalcore, grindcore |
| Industrial | Industrial, gothic, wave |
Each family is not a closed box — the map deliberately shows cross-links, which is why you see hybrid labels like "rap rock / funk metal" or "industrial metal."
How parent–child relationships are shown
The core mechanic is the derivation line. A genre that descends from another is connected to it, so the map answers questions like:
- What did drum 'n' bass come from? (It branches from the breakbeat / hardcore techno area.)
- Where does grunge sit? (Under the rock/alternative lineage, alongside post-grunge and noise rock.)
- How did synthpop relate to punk? (It appears in the new wave / post-punk region.)
This is why the map is described as a genealogy rather than a taxonomy: it emphasizes origins and evolution, not just neat categories.
Reading the map in practice
- Start with a genre you know and locate it on the chart.
- Follow the lines backward to see its ancestors (the genres it derived from).
- Follow the lines forward to see its descendants (subgenres and later mutations).
- Use the decade axis to check when a branch appeared relative to others.
The map also includes a compass-style orientation guide (the site refers to a "Carta" and a compass for how to use it), which helps you navigate without losing your place.
What Musicmap is not
- It is not a ranking of genres by popularity or sales.
- It is not exhaustive at the level of every micro-genre; it focuses on the main genealogical lines.
- It is ad-free and states it does not use personalized ads, and it collects only anonymous statistical data via cookies (with an accept/decline option).
If your goal is to see how one style grew out of another across more than a century, the genealogy structure is the whole point — and the fastest way in is to pick a genre and trace its lines in both directions.
