Spectrum for Piano Duet is a unique collection of contemporary works for piano, four hands. The newly commissioned pieces range in standard from Grade 3 to Diploma and are suitable for pianists of all ages. Seven pieces have easier Secondo parts, for teacher-student and mixed level pairs. Alongside the established composers represented are six young composers, who have each contributed a variation on Howard Skempton's theme, 'Primary Colours'. A CD is included, containing recording of all pieces, performed by Thalia Myers, Timothy Salter and Edward Liddall. The CD also includes recorded parts for the three pieces composed for piano duet and soundtrack. The highly successful Spectrum series was established by ABRSM and Thalia Myers in 1996, and now includes volumes for piano, cello, clarinet and string quartet. The aim of the series remains unchanged: to commission some of the finest composers to writes pieces of modest length and difficultly, while preserving the essential characteristics of their compositional style.
