Most online lessons are delivered using Zoom. Just make a free basic account at and download the software.
On the most basic level, any camera or microphone will work. Usually the built in camera and microphone on a laptop works well. However, you can also use a smart phone for both audio and sound using the zoom app if you need.
Due to delay issues it isn’t possible for me to accompany you live over zoom. Instead, I have found backing tracks very useful. These will need to be played from your end, ideally from a device separate to the one you’re calling from (this could be an external speaker or just your phone).
