The first flat key signature is the key of F, or its relative minor, which is D minor (Dm). These keys have a single flat note: B flat (Bb). The other six pitches are natural.
What does 2 flats in the key signature mean?
A double-flat is the equivalent of two flats, and lowers a note's pitch by two half steps. The double-flat symbol (♭♭) is placed before a note like other accidentals.
