Music Glossary

Plain-language definitions of the terms you encounter in vocal training and songwriting. Each entry links to the relevant Main Act school so you can train the skill, not just read about it.

Studio Mix

EQ (Equalization)
A process for boosting or cutting specific frequency ranges to shape a sound or fit it into a mix.
Compression
A dynamics process that reduces the loudest parts of a signal so the overall level can be raised, evening out a performance.
Reverb
The persistence of sound in a space after the source stops, simulated digitally to add depth and a sense of place to recordings.
Sidechain Compression
A compression technique where one signal triggers the compressor on another, most famously, kick drum ducking the bass to create separation.
Gain Staging
The practice of setting appropriate levels at every stage of the signal chain so nothing clips or chokes the next process.
