This note E is written in the fourth space of the staff.
Practice the high F note by changing octaves between this note and the low F note. The only fingering change required is the movement of the left thumb between completely covering the hole (low F) and half covering the hole (high F). It may take a bit of practice before you can get the high F to sound consistently. Practice it for a short time each day and be patient. In time, you will have no trouble playing this note.
