How do you locate the F flat on the staff?

Answer 1

Write a note (half note, quarter note or a whole note, it doesn't matter which) on any line or space where the "F" note in situated, then put a flat symbol in front of any note which sits on an "F line" or "F space".

Just above the first line on the treble clef is where "Middle F" is located, so you'd just write a music note on that space and put the flat sign directly before it.

Hope that helps.
