Carulli was among the most prolific composers of his time. He wrote more than four hundred works for the guitar, and countless others for various instrumental combinations, always including the guitar. His most influential work, the "Method, op. 27", published in 1810, contains pieces still widely used today in training students of the classical guitar. Along with numerous works for two guitars, works for guitar with violin or flute, and three concertos for guitar with chamber orchestra, Carulli also composed several works for guitar and piano (in collaboration with his son, Gustavo).
