Alfonso Rendano (1853–1931) was an Italian pianist and composer. He is mostly renowned for inventing the "third pedal", which augmented the interpretative resources of the piano.
Rendano was born in Cosenza. He was particularly precocious and at the age of ten he was admitted to the Naples Conservatory, where he was noticed by Sigismund Thalberg who sent him to Paris, recommending him to Rossini.
In 1866 he studied under Georges Mathias, Chopin's pupil. For about 15 years, he carried out an intense musical activity; he then devoted himself to teaching: first in Naples, then in Rome.
Rendano wrote the opera Consuelo, successfully staged in Turin and in Germany. He held his last concert at Rome's Teatro Valle in 1925. He died in Rome in 1931.
The main theatre of Cosenza is named after him.
