Minor scales

  1. Natural minor scale can be located by finding the 6th note of its relative major. What's more, it strictly uses notes from its relative major (Aeolian mode).
  2. Harmonic minor scale are all the same notes (as the natural minor) except for the 7th note which becomes a half-step relationship between the 7th note and the (next) root note
    • So, A-B-C-D-E-F-G#-A instead of A-B-C-D-E-F-G-A (with A being the next root note)
  3. Melodic minor scale which is different when going up the scale as compared to when going down the scale
    • Going up the scale becomes A-B-C-D-E-F#-G# (so, the 6th and 7th notes are raised a half step)
    • Going down the scale, however, reverts to the natural minor scale: G-F-E-D-C-B-A

Chords (technically) out of key

Chords:

  • IV major chord in, for example, the C Major scale: F-A-C (major chord) becomes F-A♭-C (minor chord)
  • vii° diminished chord in for example, the C Major scale: B-D-F (diminished chord) becomes B♭-D-F (major chord)... a flat 7 major

Key changes (or, modulation)

Key changes:

  • A (whole) step-up key change
  • Useful when, for example, you get to the end of a song and it sounds a bit too repetitive, then do a step-up key change... for example, a 6-4-1 (vi-IV-I) in C Major becomes a 6-4-1 (vi-IV-I) in D Major:
    • C Major: A-C-E (A minor, 6), F-A-C (F major, 4), C-E-G (C major, 1)
    • D Major: B-D-F# (B minor, 6), G-B-D (G major, 4), D-F#-A (D major, 1)
  • Works well when the two keys share a (common) chord to help with the transition
    • For example, in C Major, the G major (5) chord G-B-D coincides with D Major, the G major (4) chord G-B-D
