CEKM 48 is a five-volume edition of the principal sections of two organ manuscripts which presumably originated in Valencia circa 1695, but eventually made their way to Mallorca. Most of the contents are by the well-known composer Juan Cabanilles, yet approximately half of the edition consists of previously unpublished music. Volume 3 contains mostly large works; all of these are previously published, but in some cases from other sources or in inaccurate editions. The other four volumes comprise mostly shorter liturgical versets, grouped by church modes. Cabanilles devoted great care and imagination to the composition of such versets, although they have been relatively neglected by modern editors; this edition thus fills an important gap in our knowledge of the foremost organ composer of the Iberian baroque.
