How To Tell The Key Of A Song With Flat Key Signatures

To tell what key a song is in when it has flats in the key signature, locate the 2nd to the last flat, and that IS the key. For example, if there are four flats in the key signature, they are BEAD. The second to the last flat is Ab, so that is the key – based on the scale of Ab which has four flats – BEAD.
