Florence, self-proclaimed "New Athens," held a unique allure for artists in the 15th century. This vibrant city attracted philosophers, architects, painters, musicians, and creators from across Europe. Rising singer and composer Heinrich Isaac seized the opportunity to launch his career there in the 1480s. Lorenzo de' Medici, the city's secret ruler, personally brought him from Flanders to Florence, offering good pay, favorable working conditions, stimulating colleagues, and access to high societal and political circles. This partnership proved mutually beneficial: Isaac gained an international platform, while Florence acquired an exceptional musician to enhance its reputation as a leading hub of civilization.
Isaac served in Florence as one of the "Singers of San Giovanni," performing in masses at the city's major religious institutions. Beyond his church duties, he catered to the Medici's private and public musical needs. His work showcased involvement in these diverse spheres.
In "O decus ecclesiae," various facets of his multifaceted role converge. The piece, with its monumental proportions, exemplifies Isaac's craft at its grandest. It utilizes a fundamental element of Renaissance music—the natural hexachord, a series of notes from C to A. The motet's structure centers on the tenor gradually ascending and descending the hexachord. While it may hold educational elements, it likely carries symbolic meanings. With four voices surrounding this framework, the text glorifies the Virgin Mary in classical allusions, showcasing Florentine Renaissance humanism.
Lorenzo's genuine fondness for Isaac manifested in various ways. Isaac not only integrated into Florentine society but possibly composed poems for his patron and even taught his children. When Lorenzo passed away in 1492, Isaac commemorated him in several works, including the motet "Quis dabit pacem populo timenti?," following an ancient model from the tragedy "Hercules Oetaeus." This piece, honoring Lorenzo and the Medici family, discards previous material for a fresh composition, anticipating German hymn poetry of the following century.
Upon Lorenzo's death, Florence's golden era abruptly ended. His weak heir, Piero, lost power and was exiled in 1494, leading to the rule of the Dominican friar Girolamo Savonarola. Under Savonarola's strict regime, complex music, like Isaac's compositions, was prohibited. Fortunately, musicians of Isaac's caliber found demand elsewhere: by late 1496, he had become the court composer for the Habsburg Emperor Maximilian I, residing in Vienna and Innsbruck for a time. Isaac's appointment brought prestige to Maximilian's court, elevating its musical reputation. The emperor granted Isaac unusually generous working conditions. Following the unrest's subsiding, Isaac was allowed to stay in Florence, serving the court from afar.
Isaac's circles at the imperial court, while diverse like those in Florence, primarily focused on providing the court chapel with an extensive liturgical repertoire. This repertoire included masses and music based on Gregorian chants. Isaac revisited a mass he had composed in Florence, incorporating the popular song "Comment peult avoir joye?," possibly known to him through Josquin des Prez's version. Reflecting contemporary themes of misfortune and natural imagery, the piece achieves unity in its voices, concealing the canon structure within the composition.
Although "Comment peult" was originally French, a German version, "Wohlauff gut Gsell von hinnen," was also popular in Germany during the 15th and 16th centuries. Isaac's decision to revise his Florentine mass likely stemmed from this discovery. The revised "Comment peult" evolved into the impressive six-part "Missa Wohlauff gut Gsell von hinnen," showcasing Isaac's mastery with its intricate textures and varied canonic treatments.
Isaac's legacy outlasted him, a testament to his unparalleled talent. Posthumously, four motets attributed to him circulated in German sources, possibly dating to his service at Maximilian's court. These motets, including "Sive vivamus," show a blend of mournful expressions and liturgical depth, highlighting Isaac's lasting influence in the realm of sacred music.
In summary, Isaac's contributions to music history reflect a unique blend of innovation and tradition, bridging diverse cultural landscapes and leaving an indelible mark on Renaissance music.
