**Short answer:** this is a course in hearing EQ, in ten short lessons. Each one has a guide to read, a demo to play, and an exercise to pass by ear. Start at lesson 1 and go in order. The first four lessons are free and need no account.

## How a lesson works

1. **Read.** A short guide. The answer is in the first lines.
2. **Hear it.** Play the demo in the guide. Flip the EQ off and on.
3. **Do it.** Open the exercise and pass the level. That ticks the lesson off here.

## Questions

### Is the course free?

The first four lessons are free, with no account. So is lesson ten, every guide and demo, and the Daily Session. Lessons five to nine each have one question to try in their guide, once a day. The exercises in lessons five to nine are part of [Mix Chops Pro](https://mixchops.com/pro), which has a 7-day free trial.

### How long does it take?

A lesson is one short guide and one level. Do one a day and you finish in ten days. There’s no clock, so go at your own pace.

### Are there videos?

No. You read a little, then you listen and do. Each lesson ends on an exercise that scores what you hear.

### Do I need to know EQ already?

No. Lesson 1 starts with what an equaliser does.

### What will I be able to do at the end?

Name a boosted band by ear, find a resonance and cut it, and fix common tone problems with cuts. How far you get depends on practice, which is why lesson ten is a daily habit.

### How is my progress kept?

A lesson is ticked off when you pass its level. Progress saves in your browser, and a free account carries it to your other devices.

### What do I need?

A browser and headphones or decent speakers. It works on a phone.

### What music does it use?

Pink noise, drum kits and songs split into stems.

## Lesson 1: *What EQ does.*

Read the guide, play its demo, then name three bands by ear in Identify.
