Using the chat function, you can use the attachment button or drag any file into the chat window to share it with your teacher/student.
Your chats are available during the lesson and in between lessons using Forte Chat.
You can access your chat outside of the lesson in the top right corner of your Forte screen and from the Students section of the Teaching Hub.

Teacher tip: remember that the Materials tab in your account is a great way to make files like music clips, video clips, and PDFs available to all students in your studio between lessons.
