I use this in my own classroom (remote learning and in person) for rhythmic dictation, melodic dictation, note naming practice, time signature practice, ledger lines, finger number drills, and much more. It has treble, alto, and bass clefs in different colors so I can see at a glance that they are using the correct clef. Students just drag and drop the notes according to the purpose, and can copy and paste each item. Background is embedded, so only the items on top of the staff can be dragged around the screen.
