Arsenio Rodríguez initially developed Son Montuno from
son. He added instrumental solos called montunos. He also added
guaguancó influence, increased the importance of the
trumpets and
tres, and added new instruments such as the
congas and
piano.
Benny Moré (popularly known as "El Bárbaro del Ritmo", which translates roughly as "The Fantastic Man of Rhythm") further evolved the genre, adding
guaracha,
bolero and
mambo influences, helping make him extraordinarily popular and is now cited as perhaps the greatest sonero.
