While fan-braced modern classical Torres and post-Torres style instruments coexisted with traditional ladder-braced guitars at the beginning of the 20th century, the traditional forms eventually fell away. Some attribute this to the popularity of Segovia, considering him "the catalyst for change toward the Spanish design and the so-called 'modern' school in the 1920s and beyond. " The styles of music performed on ladder-braced guitars were becoming more and more unfashionable; and, e. g. in Germany, musicians were in part turning towards folk music (Schrammel-music and the Contraguitar), but this only remained localized in Germany and Austria and became unfashionable again. On the other hand, Segovia 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.
