The voice of Giovanni Martinelli, a tenor mainly remembered as a great interpreter of the lyric and spinto-dramatic repertoire, had special features which allowed him to perform a wide range of interpretations. The vocal extension, which in the high pitched register reached D-flat, enabled him to go from operas like Gioacchino Rossini's "Guglielmo Tell" and Giacomo Meyerbeer's "Les Huguenots" to Giuseppe Verdi's "Otello" and also "Lucia di Lammermoor" where, in the role of Edgardo, he achieved unforgettable success both in New York's Metropolitano Opera, his home, and at the Colon Theatre of Buenos Aires.
His voice, which was of great beauty and resistance, had the seducing sharp sound typical of the "theatrical" voices, which microphones or recordings of that time do not do him justice. Giovanni Martinelli had an athletic body, he was born in Montagnana on 22nd October 1885, in the Veneto region, from a family, like many in the late '800's, of humble origin.
At a very early age he started working hard in the workshop of his father, a skilful cabinet maker. With the early manifestation of his vocal qualities, the young man was entrusted to the master Giuseppe Mandolini who was able to define and guide in a worthily manner that voice which revealed extraordinary skills.
The debut of the promising tenor took place on 2nd December 1910, with Rossini's "Stabat Mater". On 29th December of the same year, at the Dal Verme Theatre in Milan, he was proven a distinguished interpreter in Giuseppe Verdi's opera, "Ernani", where his role as lead character, enabled him to express and emphasise his characteristics of power and vocal extension, typical of the dramatic and heroic tenors.
