Music Theory I: Major/Minor Scale KS and Modes

What is the order of flats (1 flat —> 7 flats)

BEADGCF

What is the order of sharps (1 sharp —> 7 sharps)

FCGDAEB

How can I figure out what flat key I’m looking at (major flat keys)

2nd to last flat in the KS is the key name

How can I figure out what sharp key I’m looking at (major shart keys)

last # is the 7th scale degree/leading tone

Ionian mode

C (same as major scale)

Dorian mode

• Like D major but lowered the 3rd and 7th scale degree (the F# and C#)

• Add 2 flats

Phrygian mode

• LIke E major but lowered the 2nd, 3rd, 6th, and 7th scale degree

• Add 4 flats

Lydian mode

• like F major, but made the 4th scale degree higher

• add 1 sharp

Mixolydian mode

• Like G major but lowered the 7th scale degree

• add 1 flat

Aeolian mode

• same as natural minor scale

• Like A major but lowered 3rd, 6th, and 7th scale degree

• add 3 flats

Locrian mode

• Like B major but lowered the 2nd, 3rd, 5th, 6th, and 7th scale degree

• add 5 flats
