Bach: Partita for keyboard No. 5 in G Major, BWV 829Beethoven: Cello Sonata in G minor, Op. 5, No. 2Today, we’ll hear pieces by two great composers that reflect instrumental developments in their time. Bach was a dedicated keyboardist and composed for nearly every keyboard instrument. His Partita No. 5 in G Major was written specifically for a single-manual harpsichord; therefore, there are very few sustained notes. Instead, Bach uses intricate counterpoint and fugal relationships between the voices to create a densely textured and swirling set of dance movements. Beethoven, a gifted keyboard player himself, was also a pioneer in utilizing the cello as a solo instrument. In his Cello Sonata in G minor – one of the very first cello sonatas ever written – we hear the young composer beginning to realize the full potential of both instruments. He skillfully matches the sustained tones of the cello with rhythmic articulation and cascading notes in the piano. And in the final Rondo-Allegro, the piano and cello take turns carrying the lyrically playful melody and adding sparkling embellishment.
