I teach at my home in Mottingham SE9. I always teach one-to-one but encourage chamber music playing. I am fairly flexible with times although I try to teach primarily at the weekend. I charge £40 per hour (or part thereof). Youngsters are fine with 30 minute lessons but as a player becomes more advanced lessons need to be longer. Learning to play a musical instrument is a great discipline. I would not encourage learning below the age of 6. Having said that, it is never too late to learn. I do get quite a few adults who want to learn or who want to pick up where they left off as teenagers etc.
With the covid crisis, I have been teaching online for some while others are happy to come to my house where I implement distancing and other measures to reduce the possibility of transmission.
