Adagio (2008) is based on the Lydian E-flat scale (E-flat, F, G, A, B-flat, C, D) and develops in a five-part canon (violins I, violins II, violas, cellos and double basses) a looped melodic cell (E-flat, A, C, G, D, F, B-flat) in which the duration of each note is calculated according to the Fibonacci series (2, 3, 5, 8 etc.) and the duration of each note is calculated according to the Fibonacci series using the quarter note as the basic unit. Gradually, the instruments move from the low to the high register, reaching an intense climax fortissimo towards the middle of the piece (bar 30). The tension then slowly decreases until the last chord of six sounds (C, G, E, B, F sharp, D) which makes us switch without transition to another harmonic and modal colour, like an open door or an open question. This work is dedicated in friendship to the great French composer Anthony Girard.
