The Sonatina canonica for two guitars, opus 196, by Mario Castelnuovo-Tedesco (1895–1968) was composed in 1961 for the legendary guitar duo formed by Ida Presti (1924–1967) and Alexandre Lagoya (1929–1999). It was the first episode of a collaboration which led to a rich series of fine works. Conceived as a canon, the three movements in the Sonatina are a veiled homage to Domenico Scarlatti and his harpsichord music in the Spanish idiom. We have adopted Castelnuovo-Tedesco’s original score, carefully reproducing all the many annotations and indications found in the manuscripts.
