YouTube wasn't built for practicing
YouTube holds the world’s largest collection of music lessons. But hit play on the default player and you get exactly one speed, zero looping, and no idea whether the video is even at your level until you’re three minutes in and lost.
There is no speed control precise enough to slow a fast passage down without losing the timing you’re trying to learn, no A/B loop to repeat just the four bars that keep tripping you up, and no difficulty tagging to tell you whether a video is actually within reach before you press play.

Harmoniq is a practice layer built on top of that same catalog of lessons, not a replacement for it. Every video gets a precise speed slider from 0.25x to 1.25x, a frame-accurate A/B loop you set yourself, and a difficulty rating from Beginner to Virtuoso so you can find something that matches where you actually are, not just what’s popular.
Same lessons. The tools YouTube never gave you to actually practice them.
