TYPE (English)a work in two or more voice parts without independent accompaniment; (however, some works may be accompanied). The problems with this type of composition continue to be unresolved. The first problem is the form of the name of the type. Until a definitive policy is issued, use the spelling the composer used. The second problem is medium of performance. Although "part song" is not included in the list of types of composition with implied medium of performance in 220.127.116.11 exception, the New Grove definition of the type lends credence to applying 18.104.22.168 exception. Examples in the authority file are inconsistent in stating the medium of performance. Until this problem is resolved, follow the treatment in established headings for a composer's works.
