“Tandernaken, al op den Rijn” (sometimes also spelled T’Andernaken, or Tandernack) is the title of a popular 15th c. Middle Dutch tune, which was used as the slow-moving tenor line for virtuosic polyphonic settings by several 15th and early 16th century composers in Dutch, Italian, English, and German sources. In this 5-week series kicking off our 2024-2025 notation sessions, we will explore 5 of these wonderful settings, focusing at first on the ones transmitted in manuscript form, but also including some of the ones in early prints. Composers of Tandernaken settings include Tijling, Jacob Obrecht, Antoine Brumel, King Henry VIII, Paul Hofhaimer, Petrus Alamire, Ludwig Senfl, Alexander Agricola, and Erasmus Lapicida.
