The F major scale starts and ends on the note F, and it contains a Bb note instead of a B note. The high F note uses the same fingering as the low F. As with other notes, you simply blow harder.
Play the F major scale and listen for the Do Re Mi Fa So La Ti Do sound. The F major scale is shown using the key signature of F major which is indicated by the Bb symbol placed after the treble clef.
