1. Background Vocals: This is the most common meaning. Sub vocals are essentially backing vocals that are used to add depth and texture to a song. They often complement the main vocal line, creating a fuller sound. These can be harmonies, counter melodies, or simply layers of sound behind the main vocal.
2. Hidden Vocals: Sometimes, artists will use sub vocals that are almost undetectable in a mix. These might be whispers, murmurs, or even just a faint echo of the main vocal. They can add a subtle atmospheric element to the music.
3. Hidden Messages: In some genres, like hip hop or electronica, sub vocals can be used to embed hidden messages or lyrics within the track. These might be subtle enough to be missed on the first listen, but are meant to be discovered upon repeated listens.
4. Vocal Effects: Sub vocals can also refer to vocal effects like reverb, delay, or chorus that are used to create a more atmospheric or ethereal sound. These effects can be used to enhance the main vocal line, or create a separate sub vocal track.
