EQ stands for equalization, which is a plug-in intended to manipulate the frequency content of recordings and help all of the elements of music production work together sonically. Every note an instrument plays has a fundamental frequency and overtones above it, which give it a specific timbre and make it recognizable. EQ allows you to adjust the volume level of a frequency or range of frequencies within a sound, which in turn allows you to cure a sound of its imperfections by cutting unwanted frequencies and/or boosting others, all to balance out sounds so they work well with one another.

Here are some tips on how to use EQ in music production:

• Be tasteful and judicious in applying EQ.
• Work with the EQ on soloed tracks, making sure that they do not compete for fullness, clarity, or depth.
• Don’t over EQ.
• Be intentional with every part of the mix.
• Use EQ to manipulate the frequency content of the mix so that everything is balanced and clear.

EQ is a powerful tool that can easily do more harm than good, so its important to have a solid foundation for how to use it.
