Welcome to the Q&A Forum

Hi Jack! Thanks for asking a good question. Local listings are all about physical location - not about services or instruments. Google's guidelines (https://support.google.com/business/answer/3038177?hl=en) do a good job of describing this. So, your local listings represent your physical location and not the variety of services you offer. Because Moz Local relies on Google and Facebook for valid data, we'll want to find just one listing per location you operate from for the business on these platforms. You can, however, use the business description field to talk about your services, the instruments you teach, etc. Hope this helps!
