Discover the D Flat Major Scale

The D flat major scale has five flats giving us B, E, A, D and G flatted in this scale. The scales are easy to remember if you know the circle of 4ths. With each key we added one more flat.

This major scale is made from the tetra-chords from the G flat and A flat scales.

The D flat, G flat and A flat are all related to each other this is why you see the same notes and chords in them.

These scale names are also the names of the major chords in the D flat scale.

The D Flat Major Scale Numbering

The major scales have numbers that go with the notes for easy identification. You will find out later that this way of referring to numbers makes it possible to refer to all scales and chords no matter what key you are in.

Usually this is used to refer to the chords but it is also our way of building our chords from scales. When referring to chords the numbers are usually written in Roman numerals, upper case for major chords and lower case for minor chords.

The D Flat Major Key signature

This is how the key signature will look if you are in the key of D♭. The flat symbol circles the B, D and G lines and the E and A spaces in the staff.

Other flats and sharps will be marked in the music itself but the B, E, A, D and G won’t be so you have to remember them.

The flat keys spell little words as you cycle through the 4ths starting with B then BE then BEA then BEAD then BEADG and so on. This might help you remember the flats in the keys.
