Cantabo Domino in vita mea

This chant is also found in the Leon Antiphoner fol. 121r (link to the digital edition here: http://bvpb.mcu.es/es/catalogo_imagenes/grupo.cmd?posicion=247&path=26408&forma=&presentacion=pagina ) and in Madrid, Real Academia de la Historia, Aemil. 56, fol. 48v ((link to the digital edition here: http://bibliotecadigital.rah.es/dgbrah/i18n/catalogo_imagenes/descargar_imprimir_form.cmd?path=1000098&presentacion=pagina&registrardownload=0&posicion=100&posicion=100&destino=..%2Fcatalogo_imagenes%2Fgrupo.cmd%3Fpath%3D1000098%26presentacion%3Dpagina%26registrardownload%3D0%26posicion%3D100 ). These two manuscripts are representative of the 'Leon' and 'La Rioja' tradition and the palaeographical comparison between the two notated versions of chant h00015 has showed indeed some differences in the neumatic choices (melodic contour and number of notes).
