The Types of the Scandinavian Medieval Ballad: A Descriptive Catalogue is the designation for a cataloguing system for Scandinavian ballads. It is also the title of the underlying reference book: The Types of the Scandinavian Medieval Ballad: A Descriptive Catalogue, edited by Bengt R. Jonsson, Svale Solheim and Eva Danielson, in collaboration with Mortan Nolsøe and W. Edson Richmond, published in 1978 in two places: as volume 5 of the series Skrifter utgivna av svenskt visarkiv, and as volume 59 of series B of Oslo's Instituttet for sammenkignende kulturforskning . It attempts to classify all specimens of traditional ballads known in one or more of the Scandinavian languages.
Cognate ballads are assigned the same "TSB No." such as "A 38", "A 50", or "A65". It is somewhat analogous to the Aarne–Thompson classification system or motif-index for folktale studies, except that each ballad can only have one TSB No., whereas any given folktale can exhibit several motifs. The TSB divides its list of types into six groups, as below. The division essentially follows the one by A. I. Arwidsson, and Svend Grundtvig's original division in Danmarks gamle folkeviser ; however, many of the ballads Grundtvig placed in group C have been reclassified. The number of ballad types in each group in the second printed edition of TSB from 1978 is given within parentheses. Since then, more types have been added to group F. Each ballad type is given a shortdescription, including a summary of the differences of the variants of the ballad and how they differ, and comprises a list of appearances in various Nordic ballad collections. Almost all of the ballad types given in the Danish, Faroese, Icelandic, or Swedish ballad type listings also have a specific TSB type listing. Norsk visearkiv, which is responsible for the corresponding Norwegian ballad project, has decided to employ the TSB classification directly. Many Scandinavian ballad types are also easily recognised in ballad collections from other languages. E.g., the aforementioned type TSB A 38 corresponds to Child 10.
