Carl Philipp Emanuel Bach (1714-1788) was the fifth child of great composer Johann Sebastian Bach. He was an important composer in the transitional time between the Baroque and Classical periods. These pieces were composed by CPE Bach for the annual meeting of the Captains of the Hamburg Citizens Guard. Composing for this meeting was an honor, and only the most sought-after composers were commissioned. Each year the commissioned composer would compose an oratorio and a cantata. Here, we have CPE Bach’s Oratorio Hebt an, ihr Chore der Freuden, and his Serenata Der Trommeln Schlag, der Pfeifen Spiel.
