Only two hours after I had posted the latest Milk Carton (“A nameless cantus fragment”) the answer came via facebook: Julien Taurand had found that the fragment of mensural notation in the top line of CZ-Pu XI.E.9, fol. 248v is in fact the cantus line of the entire A-part (with the ouvert ending) of the ballade “Sans joie avoir”, for which the only other concordances are to be found in Codex Chantilly (fol. 23) and Pit (P-Bn f.it. 568, fol. 27v-28). I would like to thank Mr. Taurand for sharing his identification. Here is a transcription of the A-part of said ballade with the surviving notation from the fragment in black notation and the emendations taken from Codex Chantilly in grey:
A-part of the anonymous ballade “Sans joie avoir” with the surviving notation from CZ-Pu XI.E.9 (amended by using the transmission of Codex Chantilly—grey notation).
Marc’s Milk Carton: Fragment of an Ars Nova cantus line
The famous Strasbourg codex CZ-Pu XI.E.9 (see DIAMM source description), which contains a number of ars nova pieces and German tenor-songs, features on the top line of fol. 248v a nameless fragment of mensural notation. It sounds very familiar to me and everyone I’ve asked thought the same—but no one so far could quite put the finger on it. Therefore my question is: Who knows this bit of cantus and can attach it to a composition? My guess is that it is a piece of a cantus line of a three voice ars nova or ars subtilior composition:
CZ-Pu XI.E.9, fol. 248v—fragment of an Ars Nova cantus line.
PS: The puzzle is already solved! Julien Taurand found the fragment to be the beginning of the ballade “Sans joie avoir” from Codex Chantilly. See next blog for a transcription.
