Kinds of edition · From Zero to Mozart

The same piece of music comes in different editions, and they are not interchangeable. This is a reference card — know which kind you're holding, and what that means for how much to trust the page.

The four kinds

Kind	What it is	Who it's for
Facsimile	a photograph of the composer's manuscript or the first print	scholars
Urtext	the composer's text, rebuilt from all the reliable sources, with any editorial additions clearly flagged	players who want to decide for themselves
Performing / "artist" edition	the text plus a named soloist's fingerings, bowings, dynamics and phrasing	learners; following a particular school (Flesch, Auer, Joachim, Oistrakh)
Critical edition	Urtext plus a full report of every source and every editorial decision	the reference standard — e.g. the Neue Mozart-Ausgabe

What "Urtext" really means — and doesn't

German for "original text." The aim: the music as the composer wrote it, free of an editor's fingerings and interpretation.
Urtext is not the manuscript. The autograph is usually the best source but not always the last word — it can be lost, unfinished, or replaced by a corrected first edition. The editor weighs all the sources to decide the most reliable reading.
Urtext is not infallible. Where the sources disagree, the editor makes a call — and two Urtext publishers can reach different answers for the same bar.

The same phrase, two editions

80 bpm

An Urtext prints it clean like this — just the notes and whatever the composer marked.

80 bpm

A performing edition adds a soloist's fingerings, a slur, and bow directions. Helpful for learning — but every one of those marks is somebody's opinion, not Mozart's.

K.216 specifically

The reference text is the Neue Mozart-Ausgabe. The concerto's cadenzas and lead-ins are not by Mozart — the common ones are by Joachim, Auer, Franko and others, printed in a supplement. Which cadenza you play is a choice, and the page should say whose it is.
