standardized genres?

[steltz]

I've just done an edit on a page, changing "Duet" to "Single Instrument with keyboard accompaniment" because the work wasn't a duet in the sense of equal parts. I realize there is a lot of variation on how this is treated (e.g. "Single instrument with piano", "Single instrument with piano piece", etc.). Is there a page somewhere that gives recommended headings?

Thanks.
