Some years ago, while discussing the music of Olivier Messiaen with my students, the immense oratorio La Transfiguration de Notre Seigneur Jésus-Christ1 (1965-1969) caught my attention. The Calouste Gulbenkian Foundation commissioned Messiaen in 1965 to compose a new work. This work was performed in 1969 at the 13th Gulbenkian Music Festival and was entitled La Transfiguration de Notre Seigneur Jésus-Christ. La Transfiguration is Messiaen's single oratorio, scored for instrumental soloists and a huge orchestra and chorus. Only his opera Saint Françoise d'Assise (composed 1975-1979, orchestrated 1979-1983) is more extensive.
In La Transfiguration Messiaen uses all the different composition techniques typical of his work until the late 1960s. In a way, this piece gives perfect access to Messiaen’s universe. After listening to a recording and playing the score of Choral de la Sainte Montagne, the 7th movement of La Transfiguration, I was moved by the extraordinary harmonies of this chorale. The 14th movement of La Transfiguration is also a chorale. Since both chorales are completely homorhythmic, my experience as a listener is strongly oriented towards the harmonic language. In Traité de rythme, de couleur, et d'ornithologie,2 Tome VII, Messiaen explains the colours he associates with each chord of Choral de la Sainte Montagne. Messiaen has a very strong sound-colour experience according to his well-documented synaesthesia. After reading this colour-based analysis, I became curious about other approaches of analysing the harmonies and voice leading in those two chorales.
The goal of this research is to develop my own approach to the analysis of the harmony and voice leading in the two homorhythmic chorales of La Transfiguration, in relation to existing approaches, from the perspective of a theorist and performer.
Main question: How to analyse harmony and voice leading in the two homorhythmic chorales from Messiaen’s La Transfiguration de Notre Seigneur Jésus-Christ?
Sub question 1: What role does the chorale play in Messiaen’s orchestral and ensemble repertoire and what are Messiaen's views on the chorale, homorhythmic writing, harmony and voice leading?
Sub question 2: In which ways have Messiaen's harmony and voice leading been analysed over the past decades?
Sub question 3: How can the harmony and voice leading of the two homorhythmic chorales from La Transfiguration de Notre Seigneur Jésus-Christ be analysed in a way that takes into account the listening experience?
