The two Piano Sonatas in G major (Hob. XVI:6) and E major (Hob. XVI:31) occupy a special place in Haydn’s sonata output. The G major sonata is one of the most expressive of the composer’s early piano sonatas, while the E major sonata seems to have become a very popular work immediately after it was written. Their moderate technical demands make them particularly welcome teaching materials. Their fresh musical approach and contrasting variety of expression make them equally worthwhile repertoire pieces for concert performance.
