Yamaha used some technological trickery to enable Siri to play a concerto on a Yamaha Disklavier Grand Piano.
By converting a MIDI songfile into an audio file that the iPhone can play and connecting the audio output of an Airport Express to the analog input of a MIDI-enabled Disklavier piano, the iPhone can "play" the MIDI file via AirPlay and control the multi-thousand dollar piano.
As explained to The Loop's Jim Dalrymple:
Then, you simply ask Siri to play your favorite song from your iTunes library, and Siri responds immediately, by making the Disklavier’s keys and pedal move up and down, recreating the performance, including full orchestration.
