Fifths and equivalents

All columns are equivalent pitches. Each cell is a perfect fifth above the cell to its left.

Ebbbb Bbbbb Fbbb Cbbb Gbbb Dbbb Abbb Ebbb Bbbb Fbb Cbb Gbb Dbb
Dbb Abb Ebb Bbb Fb Cb Gb Db Ab Eb Bb F C

Rules and Guidelines

The 1.____ scale a perfect fifth 2.____ the current scale contains the same notes but the 3.___ in the current scale is 4.____ to become the 5.____ of the new scale.

1 2 3 4 5
major above P4 sharped M7
minor above M6 sharped M2
major below M7 flattened P4
minor below M2 flattened m6

Equivalent Pitches for Scales Below/Above by Interval

Modulating from any major scale to a new major scale that is ___ interval above/below the original key has ___ same pitches and #/b per note:

Interval Above Root Uni m2 M2 m3 M3 P4 d5 P5 m6 M6 D7 M7
Interval Below Root Uni M7 D7 M6 m6 P5 d5 P4 M3 m3 M2 m2
Example Major Key vs C Major C C# D D# E F F# G G# A A# B
Number of Common Pitches 7 2 5 4 3 6 2 6 3 4 5 2


Which means the most harmonic key changes are:

Common Notes Diatonic Keys Non-Diatonic Keys
6 P4, P5
5 M2 D7
4 M6 m3
3 M3 m6
2 M7 m2, d5

* Note: All intervals in above table are above the root note
