The SMA and the editors of Music Analysis were sorry to learn of the passing of Philip Lambert. Through his work on Charles Ives, transformation theory, as well as music theatre and popular music, Lambert has left a profound mark on our discipline. Adding to his important catalogue of books and articles, he recently published a ground-breaking essay in Music Analysis (39/iii) entitled “Half-Diminished Seventh Chords and Their Contexts”. The article has now been made available on an open-access basis for a limited period. Please feel free to download and read it here:
