I have taken this video from my favourite classical guitar teaching site, Bradford Werner’s Thisisclassicalguitar.
This what Bradford writes concerning this performance:
Lorenzo Bernardi Plays Confesiòn by Paraguayan guitarist and composer, Agustín Barrios Mangoré (1885–1944). This comes via Bernardi’s Youtube Channel. Guitar made by Philip Woodfield. Some nice musical playing by this young Italian guitarist. “Also known as Confesión de Amor (Confession of Love), Confesión is an example of the genre known as romanza, a slow, melodic piece in duple metre expressive of romantic feeling. Barrios wrote this work in 1923 and recorded it on 21st June, 1928. Here he places the melody in the bass register with the harmonic accompaniment in the upper voices. A profound knowledge of the instrument is necessary to achieve this type of textural writing, and Confesión, together with his Romanza en Imitación al Violoncello, is a masterful display of virtuosity and skill.
I have posted Barrios’ Confesion before but I particularly like this interpretation.
