The String Quartet no. 4, subtitled "Dedication", was commissioned by the CNDM of Madrid to celebrate the 250th Anniversary of Beethoven and was written for, and dedicated to, the Cuarteto Casals (2017). This one-movement work,lasting some 11 minutes, is based on a small motif from the op quartet. 130 as a tribute to the German master. The work, that explores the full range of the technical, musical, and emotional scope of the quartet medium, has aternary arrangement, with a slow introduction and a conclusive stretta on the B-flat note (like the one that opens Op. 130). Its course includes marked contrasts between the contemplative, lyrical, static and suspensive sections -in the manner of stagnations - and those with a more lively tempo, playful and occasionally festive.
