Gianmario Liuni began studying jazz piano at age 15. At the time, he also studied guitar with Maestro Mario Trama. He attended Maestro Arrigo Cappelletti's courses at the CDM music school of Milan. He participated in Siena 's summer jazz seminars, studying piano (Maestro Franco D'Andrea), ensemble music (Maestro Stefano Battaglia), and harmony. He studied advanced piano technique and classical repertoire with pianist Barbara Tripodi. He studied with Maestro Franco D'Andrea at the CPM European Music Institute in Milan, where he earned a diploma in jazz piano, receiving highest marks, in 1998. He pursued his studies in harmony, orchestration, and composition with Maestro Umberto Fusco. For some years until 2010 expanded the classical repertoire and studied the techniques of composition with Maestro Marco Iannelli (pianist, musicologist, and symphony conductor).

CD recordings of his compositions:

2019: "Gianmusicario" (publisher: Advice Music).  This possible self-portrait of the author is portrayed through a musical kaleidoscope where the whole image fragments into nine original pieces. The compositions present different ensembles, from more elaborate ones with a string quartet (Khora Quartet), winds (Giulio Visibelli), guitar (Luca Meneghello), piano (Gianmario Liuni), electric bass (Marco Ricci) and drums (Martino Malacrida) to the classic jazz trio. Rhythms, tempos and sonorities vary and, almost involuntarily, sum up the expressive world of the pianist-composer.

2016: "Stabat Mater" (publisher: Advice Music). In this sacred music composition, Liuni's unique and special homage is written for a chamber quintet, the members of which are Eleonora D'Ettole (mezzo-soprano), Giulio Visibelli (transverse flute), Sandro Ceccarelli (French horn), Stefano Dall'Ora (Contrabass) and the composer at the piano. The piece, based on the renowned poem-prayer by Jacopone da Todi, is in five movements. In addition, there is a "Salve Regina" and a piece titled "Dolce Signora", for which Liuni also wrote the lyrics.

2014: "Upriver" (publisher: Advice Music) is released. In this CD the ensemble welcomes a new addition: Gianluca Alberti on bass. The project explores electric jazz, introducing new rhythms and moods (Tango, Latin, Blues, Rock…). Its wide-ranging selection of elegant, dynamic and poetic pieces gives us a taste of the composer's musical world.

2012: "Happy Choice" (Ed. Advice Music). Liuni seeks new paths of expression, embracing the electric jazz-rock world with its unusual rhythms and sounds. His excellent band – featuring Luca Meneghello on guitar, Alessio Pacifico on drums, Marco Ricci on electric bass, Giulio Visibelli on soprano sax and Gianmario Liuni on electric piano and keyboards, ensures this splendid overall result.

2011: For the fourth edition of “Il libro della Passione” (Publisher: Ares), the "Quadri della Passione" CD, included with the book, is revised and updated. Excerpts are added of the poem read by Cesare Cavalleri, with new compositions by Liuni and the participation of Elio Marchesini on percussion.

2010: "Jazz Variations", is published by Advice Music: a unique work based on the classic form of variations on a theme. Alternating in the variations are a jazz trio (with Marco Ricci on electric bass and Alessio Pacifico on drums) and the string quartet of the La Fenice Opera House of Venice, which also performs the entire “Quartet for Strings N.1”.

2009: Rugginenti Editore publishes a score for two pianos with the title "Politango".

2008: Liuni releases a double CD in homage to the life and works of Florentine poet Alberto Caramella (1928-2007). The title, "Il Soggetto è il Mare"  (Ed. Advice Music; CDAM 014), comes from the collection containing all the poet's previous works inspired by or in some way alluding to the sea as the absolute protagonist. The songs are interpreted by the splendid voice of Maria Patti accompanied by the quintet with Liuni on piano, Alessio Pacifico on drums, Elio Marchesini on percussion, Marco Ricci on the electric bass, and Sandro Cerino on wind instruments.

2007: "Tricercando" published by Advice Music, a work entirely dedicated to the jazz trio and featuring faithful colleagues Tito Mangialajo Rantzer and Alessio Pacifico.

2006: "Conversation with Africa" , published by Advice Music. Although it features the same artists appearing in "Un soffio soltanto", this work is much different due to its strong rhythms and an African flavor inspired by jazz and not ethnic origins.

2005: Advice Music editions publish "Un Soffio Soltanto". The project, taking as inspiration the central texts of poet and theatrical author Mara Cantoni, with the participation of the singer Daniela Panetta and the winds of Sandro Cerino and Giulio Visibelli.
