In music, a “major” key is a key with a major third distance between the first note – the “ root” note – and the third, creating music that carries a “happy” sound to our ears. There’s quite a bit more vocabulary to unpack, so we will do so now. An A flat major scale is one such scale set in the tonality of A flat major, a major key containing four flats.

Now a musical “scale” is a graduated sequence of notes dividing an “octave”, or set of eight notes.
