Duet piano concerto for the piano beginner. Violinists have concertos in plenty for beginners – now pianists have one! PIANO EXPLORER – Stephen Baron. With a basic piano technique, the beginner will enjoy the inventiveness of these pieces – with forays into the black keys, whole-tone scale, and the church modes as well as the technical challenges of chords, pedals, crossing hands, counterpoint, harmonics and percussive effects on the piano lid.
