Pietro degli Antonii (16 May 1639 – 25 September 1720) was an Italian composer.
[1] Pietro degli Antonii, son of a trombonist, spent his entire life in Bologna where he was born and died and around 1670 became a member of the prestigious Accademia Filarmonica, of which he was elected chairman several times.
With his brother Giovanni Battista degli Antonii [de] (1636-1698) and Giovanni Battista Vitali, he is regarded as an important representative of the Bolognese School [de] after Maurizio Cazzati.
His preference for slow, melodious movements based on singing is particularly noteworthy.
In addition to instrumental compositions, he created numerous cantatas.
