Unlike regular audio files like MP3s or WAVs, these do not contain any actual audio data and are therefore much smaller in size. Instead, they explain what notes are played, when they are played, and how long or loud each note should be.
Files in this format are basically instructions that explain how the sound should be produced when connected to a playback device or loaded into a particular software program that knows how to interpret the data.
