ABSTRACT:
Keyboard practice glasses to be worn over the eyes of a student who is learning to sight-read sheet music, which completely prevent the keyboard student from accidentally looking down at his hands on the keyboard while allowing the student full view of the sheet music. The glasses comprise paired lens portions each of which is divided substantially in half to produce a clear region for viewing the sheet music and an opaque or translucent region which prevents viewing of the hands on the keyboard.
