Customer Service
Have an issue regarding a purchase? Please email us at the address below. We'll reply ASAP (usually within 48 hours).

YouTube Comments
We premiere a video every Saturday at 12 noon (PT), then we hang out on YouTube for an hour, replying to as many comments on that new video as possible. We'd love to meet you, so come say hello on our next video!

Theory / General
We read every email, and we're deeply grateful for your interest in Hack Music Theory. As we get hundreds of theory questions and general messages though, we're unfortunately unable to reply to these emails.

Social Media
We are not on any social media. If you're wondering why, you are in luck, cos we wrote a song about it! So, if you want more access to us, then join the Apprenticeship and you'll gain access to our private Network.
