MIDI (Musical Instrument Digital Interface) is a technical standard that describes a communications protocol, digital interface, and electrical connectors that allow a wide variety of electronic musical instruments, computers, and other related devices to connect and communicate with one another. Unlike MP3 or WAV files, MIDI files do not contain actual audio data. Instead, they contain instructions or 'messages' that tell a hardware or software synthesizer how to produce sound. These messages include note pitch, velocity (how hard a note is played), volume, vibrato, panning, and clock signals to set tempo. Because they only store instructions rather than sampled sound, MIDI files are incredibly small in size compared to digital audio recordings. They are widely used in music production for sequencing, scoring, and controlling virtual instruments. They allow composers to edit individual notes, change the instrument sound after recording, and easily transpose music to different keys without losing quality. This format remains a cornerstone of digital music creation, live performance setups, and video game soundtracks due to its flexibility and efficiency.
