Classical guitar was playing in concerts around the world, popularizing his modern classical guitar, as well as a new style of music in the 1920s: Spanish romantic-modern style with guitar works by Moreno Torroba, de Falla, etc. Some people consider it to have been this influence of Segovia which led to the domination of the Torres instrument. Factories all over the world began producing them in large numbers. It was the 19th century classical guitarist Francisco Tárrega who first popularized the Torres design as a classical solo instrument. Composers of the Renaissance period who wrote for four course guitar include Alonso Mudarra,
Classical guitar it is my constant companion in all my travels". He also said, on another occasion: "I do not like this instrument, but regard it simply as a way of helping me to think" The guitarist and composer Francisco Tárrega (b. Vilareal, Spain in November 29, 1852-d. December 15, 1909) was one of the great guitar virtuosos and teachers and is considered the father of modern classical guitar playing. As professor of guitar at the conservatories of Madrid and Barcelona, he defined many elements of the modern classical technique and elevated the importance of the guitar in the classical music tradition.
