What does MIDI data include?

MIDI data, or Musical Instrument Digital Interface, is a protocol that allows electronic musical instruments, computers, and other equipment to communicate with each other. One of the key features of MIDI data is its ability to transmit performance information such as notes played, timing, and various control signals. Among these many details, tempo settings are critical as they dictate the speed of the music being created or performed. This means that MIDI data not only includes the pitches and durations of notes but also timing information that determines the tempo at which the music is played.

Other options do not measure up to the scope of MIDI data. Instrument price points and player biographies involve commercial and biographical information, which MIDI does not address. Likewise, live concert recordings are audio files capturing performances rather than data about the performance itself. Thus, the inclusion of tempo settings in MIDI data is what makes it essential for shaping and controlling the music.
