Unquestionably Manuel María Ponce stands as one of the composers for the classical guitar of all time. Rare would be the virtuoso who does not acknowledge his brilliance. However, to reach such heights, history had to gift us a providential encounter with the greatest ambassador of the guitar in the 20th century: Andrés Segovia. Their profound relationship of friendship, respect, and admiration, evidenced through a fraternal correspondence and declarations, began in 1923. Manuel Ponce composed the Sonatas between 1923 and 1929, all commissioned and dedicated to Andrés Segovia. They constitute the first collection of Sonatas written in the 20th century by a non-guitarist composer, forming a fundamental and unique corpus in the concert guitar repertoire. Each Sonata possesses stylistic and formal characteristics that Segovia himself detailed.
