Regondi's guitar compositions reflect not only his gentle nature but also the high romanticism of his period. The discovery by Matanya Ophee of 10 Etudes, previously thought to be lost, compelled a revaluation of Regondi's contribution. The two Airs Variés, Op.22, and Op.23, can only reinforce the new respect that ensued. Each begins with a slow introduction, followed by an Andante theme, slightly operatic in character, after which come a number of variations (four in Op.22, five in Op.23) that show off the resources of the instrument: brilliant passages of demisemiquavers (32nd notes), a minor-key tremolo, consecutive ninths and triplets.
