While improvements have been made in manufacturing processes, and many individual details of the instrument continue to receive attention, and a small number of acoustic pianos in the 2010s are produced with MIDI recording and digital sound module-triggering capabilities, the 19th century was the era of the most dramatic innovations and modifications of the instrument. Upright pianos are widely used in churches, community centers, schools, music conservatories and university music programs as rehearsal and practice instruments, and they are popular models for in-home purchase.
