Query: Musical Doorbell

This is a delightful item, giving you many options to greet visitors at the door. From reading reviews before purchase, we did add anauxiliary speaker (actually the existing one from our old musical doorbell-- different kind). We aren't musically inclined but look forward, when we have the time to figure out the process, to programing in our own songs on the keyboard. It was easy to install.
