Teacher of accordion at the Musical Institute of Valle d'Aosta, Dellarole studied with Emanuele Spantaconi and Sergio Scappini and then he specialized in the performance of the ancient repertoire with Marco Farolfi, Emilia Fadini and Luca Oberti.

Through his concert activity he has brought the accordion to very important concert venues where he has performed all over Italy, in Europe (France, Germany, Switzerland, Austria, Poland, Romania, Greece, Czech Republic, Slovakia) and in China, Africa and United States. His performances have also been recorded for the Italian broadcaster Rai1 and Radio 3 (“La stanza della musica” and “Piazza Verdi”), for the African International Television and for Polish and Greek national broadcasters.

He has recorded as soloist and with chamber ensembles from duo to sextet, performing early music (he has recently recorded some Sonatas by Domenico Scarlatti for Velut Luna), and contemporary and Tango repertoires.

He has been awarded prizes in international competitions and has been selected by ARAM and Gioventù Musicale d'Italia.

Dellarole has played as a first execution, among others, pieces by Nicola Campogrande and Angelo Gilardino and he often collaborates with musicians such as Michele Andalò, Fiorella Andriani, Luigi Attademo, Bruno Cavallo, Gabriele Geminiani, Lorenzo Micheli, Alessandro Palmeri, Rocco Parisi, Emanuele Segre and Alessandro Tampieri.

Through his activity he intends to enhance the manifold performing possibilities of the modern accordion, trying to free it from the folk context it has always belonged to.

In the last years he has devoted himself mainly to the study of the baroque and classical repertoire, being one of the first to bring the accordion to the experts' attention. At the same time, through the courses and master classes he holds, he tries to diffuse the idea of a rigorous philological and stylistic research applied to early music among the accordionists.

Dellarole plays an accordion by Bugari, model Bayan ACTIVA of 2009, tuned at 415 with “Vallotti” system.
