Hello! I noticed Music Theory isn't yet included on Khan Academy. As someone learning piano and violin by ear, I think the next step is definitely how to read sheet music fluently. I would love to see you guys introduce courses associated with music as I really admire Khan Academy's teaching style. Since music is also full of patterns, I think it would fit in nicely alongside the maths and sciences and of course in Arts and Humanities. Looking forward to hopefully seeing this course in the future! Best, Emily
