Even into the 20th century, lyra viol music was often misidentified in library catalogs. Some catalogs still retain these misattributions. Differentiating between tab for lute and lyra viol music requires careful examination of the music by an expert. Broken chords, and strings marked below the tablature lines are clear indications the music is not suitable for the lyra viol. Additionally, some catalogs lump lyra viol music with division music. Though this is a minor point, lyra viol music is traditionally set in tablature. Division music is traditionally set in staff notation.
