About this site

This is a searchable, browsable database of classical and concert-music composers, spanning the Medieval era through the 21st century. "Concert-music composer" is used deliberately—the scope is instrumental/vocal art music (symphonic, chamber, choral, operatic, and related traditions), not popular or commercial music, even where a composer's home-country Wikipedia list draws that line loosely.

Alongside search, composers can be browsed by era, genre, nationality, instrument, and tag, and—where the relationships are known—by teacher/student lineage.

How the data is built

The starting point is Wikipedia: era-based composer lists (Medieval, Renaissance, Baroque, Classical, Romantic, 20th- and 21st-century) plus dedicated national lists for languages/countries with a lot of composers not well covered by the English-language lists alone (Hungarian, German, and others).

From there, each composer is cross-referenced against Wikidata, which supplies structured facts: birth/death dates (including which calendar the date was originally recorded in—Julian dates that predate a given country's switch to the Gregorian calendar are flagged, roughly for dates between the 1582 Gregorian reform and Russia's 1918 switch), nationality/citizenship, family and professional relationships, instruments, notable works, and links to Wikipedia articles in other languages.

That combined data is then cleaned by hand: duplicate entries for the same person arriving under different-language spellings are merged; nationality is tracked carefully—distinguishing citizenship from ethnicity from a birthplace-only origin, and flagging inferred-rather-than-confirmed tags—since Wikidata and Wikipedia often blur these together, especially for composers who lived before the modern nation-state made "citizenship" a well-defined status at all.

Zdroje

• Wikipedia—composer lists (by era and by country/language) as the initial source of who's included, plus the linked articles themselves.
• Wikidata—the primary source for structured facts once a composer is identified: dates, relationships, nationality claims, works, and images.
• Occasionally, a specific gap or disagreement between Wikipedia and Wikidata is checked against another verifiable, independent source (e.g. a record label's liner notes, a specialist reference work) rather than guessed—always noted as an exception, not the default sourcing method.

A note on accuracy

This is an independent, actively maintained project, not an official or institutional reference. The dataset keeps growing and getting corrected as gaps and mistakes are found—it does not claim to be complete or error-free. If something looks wrong, it probably reflects a genuine gap or disagreement in the underlying sources rather than a deliberate claim.

Feedback

Spotted an error, or have a suggestion?

Even better: fix the data directly on Wikidata, then ping me and I'll fetch the corrected version.

Or if you can help me on Wikidata, you can find a list that needs to check and change there.

None of this would exist without the volunteer editors of Wikipedia and Wikidata, whose ongoing work—writing articles, sourcing facts, and maintaining structured data—is the foundation this whole site is built on.
