I want to know the answer to the following question:
Keyboard instruments included the pip organ, harpsichord and what other instrument?
All the background I'm provided with is that "Whereas a classical era string quartet consists almost exclusively of two violins, a viola and a cello, a Baroque group accompanying a soloist or opera could include one of several different types of keyboard instruments (e.g., pipe organ, harpsichord, or clavichord), additional stringed chordal instruments (e.g., a lute) and an unspecified number of bass instruments performing the basso continuo bassline, including bowed strings, woodwinds and brass instruments (e.g., a cello, contrabass, viol, bassoon, serpent, etc.).". Is that enough to answer the question?
Answer: yes
