Musical temperament is an evaluation of the quality of intervals between sounds. It is at the centre of musical creation today, especially in the Mediterranean region. Between the modality of Maqams and their subtle micro interval changes (commonly known as a quarter tone) from one region to another and the even temperament of western music with its theoretical division of the octave in 12 equal parts, several different methods have developed over time. Whether through juxtaposition or superimposition, the coming together of these styles often results in friction because of the very nature of the instruments used. The oud and the piano are two well-known examples of instruments that symbolise this desire to come together but who must overco >>>me their very nature to do so. The even temperament of J-S Bach’s piano pieces allowed for the emergence of a vast musical heritage anchored in musical scores as well as in improvisation. His creations gave us the necessary tools to modulate harmonies by transposition. The development of the counterpoint and the discovery of previously unheard of polyphonies also multiplied expressive possibilities. Uneven temperament, on the other hand, contains a variety of modes ranging from the countless melodic details in Arabic music from the Balkans or the Maghreb region, all the way to India, regions of Africa or of China. Since ancestral times, these styles are the carriers of memories that continue to produce new melodies, colours, and feelings. These creations carry stories that are constantly being renewed and transcended. Reflecting on how to bring together these different temperaments is an important issue in the world of music in the 21st century. Uneven temperament is faced with the challenge of harmonisation just as temperate harmony is faced with the challenge of microtonality. ‘Harmonising Maqams’ offers a dynamic experience between the composer, and trumpet and santur player Amir Elsaffar, and Medinea musicians. Through this module, we can follow the process of instant collective composition from its early stages right up to its official unveiling in concert. All along the journey, we will see aspects of the process of harmonizing Maqams thanks to the unique experience of Amir Elsaffar. Far from being concerned with dogmatic theory, this module allows us to share the fruits of this unique experience. The collective composition and the concert can be listened to via the link the Medinea session in Istanbul’s page.  <<<
