Nadia Boulanger’s fame as a 20th century music pedagogue is iconic. She has been described as ‘the most influential teacher since Socrates’ and her list of former students reads like a Who’s Who of professional musicians today. Boulanger taught what she described as a ‘draconian technique’ but she never published any teaching materials. Boulanger’s technique can be best understood, through the voice of her students, as musicianship skill development with singing at the core. Boulanger’s convictions about teaching technique echo that of Kodály’s on musicianship. Interestingly, although they were contemporaries it would appear they never met during their lifetimes. This paper will be a practical presentation which gives insight into Nadia Boulanger’s musicianship world in order to rediscover her genius and timeless relevance to quality music education today.
