New work for oboe “Hobojo Op. 21” – Francisco José Valero Castells.

“Hobojo Op. 21” – Francisco José Valero Castells.



This composition, “Hobojo Op. 21”, is dedicated to all students who have attended my oboe classes over 30 years in which I have been teaching at the CSMM.

Fibonacci sequence has been used in this composition as the inspiration element with the aim of obtaining the germ of it.


Then, a section appears in which students, who have studied with me, have taken part, also, students who are studying with me as of today (63). Their contribution consisted in composing and recording their names to take part of the composition in an active way; 27 students have participated in this process.

At the end of this section, a short space has been given to the player to include his name and surname in the composition, if it is his wish.

As a final section, there is a Cadence that incorporates, as a summary, a set of three previous sections. The cadence is formed by three elements, two of them are a tribute as an ostinato (theme B-A-C-H and the note B of the Berio “Sequenza VII”). The third one corresponds to the Fibonacci scale. Small sections are articulated on these elements, as one of the whole composition. As the “last task”, the existence of a message hidden in the cadence has to be mentioned.
