Lessonface connects music students with friendly, knowledgeable teachers for face-to-face practice sessions. What's more, they do it via video-conference software, so it doesn't matter if clients are too busy to schedule an appointment in person, or if they're a sentient program trapped in a desktop computer. The choices are staggering: teachers are on hand for four kinds of guitar playing, full string sections, percussion instruments from drums to djembes, and vocal lessons from opera to hip-hop. For those that love music but don't want to play, they even offer mixing and digital-mastering lessons and music theory.
