Aguado's major work Escuela de Guitarra was a guitar tutorial published in 1825.[1] As of 2011, it is still in print, with Tecla Editions releasing a reprint in 2005.[2] In the Escuela Aguado describes his use of fingernails on the right hand as well as his invention of a "tripodison": a device that held the guitar and thus minimized the damping effect of the player's body on the guitar's back and sides.[3] Aguado's other works include Trois Rondos Brillants (Opus 2), Le Menuet Affandangado (Opus 15), Le Fandango Varie (Opus 16), as well as numerous waltzes, minuets, and other light pieces.
