Intro

The opening section of a song, typically 4 to 16 bars. Its job is simple: establish the key, tempo, mood, and energy level before the main material begins. An intro can be a repeated guitar riff, a drum pattern, a synth pad, ambient field recordings, or even a single chord held under spoken words. Some intros are minimal - just a voice and a breath. Others preview the chorus melody in a stripped-down form. The intro answers one question for the listener: 'do I want to keep listening?' A good intro doesn't overstay its welcome. It invites you in, sets expectations, and then moves on. No chorus, no climax - just a handshake.
