Giovanni Battista Martini,
(24 April 1706 - 3 August 1784),
also known as Padre Martini, or
Giambattista Martini, was an Italian Conventual Franciscan friar, who was a leading musician and composer of the period.
Giovanni Battista Martini was born at Bologna, in that era part of the Papal States.
His father, Antonio Maria Martini, a violinist, taught him the elements of music and the violin and later learned singing and harpsichord playing from Padre Pradieri,
and counterpoint from Antonio Riccieri
and Giacomo Antonio Perti.
Having received his education in classics from the priests of the Oratory of Saint Philip Neri,
he afterwards entered the novitiate of the Conventual Franciscans at their friary in Lago, at the close of which he professed religious vows and received the religious habit of the Order on September 11, 1722.
Most contemporary musicians speak of Martini with admiration, and Leopold Mozart consulted him with regard to the talents of his son, Wolfgang Amadeus Mozart. The latter went on to write the friar in very effusive terms after a visit to the city.
