Publisher Desc. Impromptu No. 2, Opus 7 is a nice little piece in a 20th century style. Included are modern harmonies such as 7th, 9th, and 11th chords in addition to secundal and quartal harmony. The musical materials and concepts are advanced but the technique needed is at a medium level. This would be a great modern piece for a developing student or as a change of pace selection on an advanced recital.
