French horn (F and B flat) double has MANY notes with synonymous fingerings, your embouchure (your mouth/lip position) must be specifically tuned to get ALL of that right for correct note to come out, PLUS your right hand to soften/brighten the sound. PLUS the F horn doesn't sound like a dying litter of baby squirrels. Except I'm Scots/Irish. Still bag pipes was NOT an option in band.
