Yes, you can teach piano online by using Payhip's coaching features that integrate with Calendly to easily set up private piano lessons over Zoom. As a beginner, you will need to invest in some basic equipment such as a top-down camera or a tripod that allows you to hold your phone for a top-down recording. You will also need to invest in a decent quality microphone to ensure that your students will be able to hear you clearly. You may also need to purchase a paid version of Zoom to conduct a private lesson that is longer than 40 minutes long.
