This waltz by Sor op. 39 no. 2 is full of rhythm with high notes for both of the guitars. The dance-floor should be kept firmly in mind throughout.
This is no. 2 from Sor’s Six valses op. 39 for two guitars which he published in Paris in about 1829-30. You can hear it here played by Claudio Maccari and Paolo Pugliese.
