I made a short analysis video on Carlo Gesualdo‘s Miserere from his Responsories for Holy Saturday. The chord progressions at the beginning, enriching modal harmony with chromaticised voice-leading, can be regarded as transformations according to Neo-Riemannian theory, and made visible as triadic relations in an Eulerian Tonnetz. This is a rather simple yet fascinating example that suited me well for a first approach to teaching transformational theory.
Also, for those of you who are interested in my compositions, there are some new recordings available on SoundCloud: a folk song duet from my Lyric Diptych for two voices and piano, and two excerpts from the suite At the Forest Verge for guitar and marimba duo.
