CAMBRIDGE – Blue Heron’s Ockeghem@600 project has steadily worked its way through much of the composer’s repertoire. On March 9th at First Church, one of the most special evenings of this series was performed: Johannes Ockeghem’s Missa Prolationum. The mass is constructed almost entirely out of a set of double canons, presenting imitative counterpoint throughout and at every scalar interval (a feat only matched by Bach’s Goldberg Variations, but Bach’s include single, not double, canons). The jaw-dropping intricacies of this work’s construction, and the comparative irregularity of its presentation on concert programs, made me more than happy to make the trip from New Jersey to Boston to experience it live.
Johannes Ockeghem, who died in 1497, was during his lifetime highly esteemed as both a composer and singer (some say the low bass lines one sees in his music would likely have been performed by Ockeghem himself). A number of composers and theorists referenced his music, employing it in paraphrase and parody works and holding it up as a paragon of craftsmanship. One of Josquin’s most affecting pieces is Nymphes des bois, a Déploration on the death of Ockeghem. So why isn’t he a household name today among choral enthusiasts? The challenges posed by pieces like Missa Prolationum keep them beyond the reach of any but the most skillful and dedicated ensembles. This is where Blue Heron’s Ockeghem@600 project comes in, raising both awareness for the composer and demonstrating that, while formidable, his is eminently singable music.
Scott Metcalfe, Blue Heron’s director, carefully curated the program both to elucidate and to entertain. The concert opened with a brief canonic work by Jean Mouton, Ave Maria gemma virginum, which served as a talking point for a brief but animated lecture by Metcalfe. The singers of Blue Heron helped him to illustrate several musical examples that explicated the process of canon and how it was used by Ockeghem. Further demonstration of canonic procedure was provided by Prenez sur moi, one of Ockeghem’s most famous songs.
The program continued by interspersing some of Ockeghem’s songs with movements of the mass. Given the compositional rigor of Missa Prolationum, the inclusion of other music smartly broke it up into more manageable chunks for listeners. It also served to demonstrate the composer’s versatility; the chansons may not include double canons like the mass but are equally inventive in their own respective ways.
Throughout, Blue Heron sang with impressive tone, flawless intonation, and incisive rhythmic clarity. Indeed, the latter characteristic was particularly efficacious. One of the chief rewards of their rendition of the mass was being able to hear, clearly delineated, a veritable labyrinth of interlocking rhythms. As is their practice, Blue Heron shifts around the members of the ensemble (numbering nine singers plus Metcalfe directing and playing harp) from number to number. The upper part features both male and female voices and the rest of the singers, when singing solo, are heterogenous in tone color as well. However, when they join voices, the group adopts a resonant and supple blend.
The performance was inspiring, and the onstage remarks were spot-on in terms of content, level of detail, and duration. In addition to memories of the fine music-making, audience members left with another keepsake: a lovingly curated and detailed program book that was remarkably in-depth for such a document. It was yet another indication of the level of commitment that Metcalfe has brought to the Ockeghem@600 project. Blue Heron’s forthcoming recording of Ockeghem’s complete songs is not to be missed.
