What does “B.” followed by a number mean in regards to classical music?
Question by Cameron L: What does “B.” followed by a number mean in regards to classical music?
I know that “Op.” is the opus number, but I noticed in some of the music I downloaded recently that many of the pieces have “B.” followed by a number. All of the pieces have this, but many lack an opus number. Have any idea what this means?

Usually that method is used for older music that wasn’t published; it refers to the name of the person who categorized the music. So you have K 331 for Mozart (Köchel), D for Schubert (for Deutsch), and BWV for Bach (Bach Works Catalogue). You rarely see it after Schubert- after that music was generally published in opuses. I don’t know who “B” is, but if this label is applied to a particular composer, it’s probably the person who categorized it.
If the B applies to a bunch of different composers, then I don’t know what it is.
Perhaps it is a numbering system the place you downloaded from uses. You can ask them.
It’s a catalog number
Jarmil Burghauser cataloged Antonín Dvořák’s works, so they are assigned a B. number.
Op. 95, The New World Symphony is “B.178″
“Impromptu in D minor (for piano)” has no Opus number, but is “B.129″
