  • The lowest horizontal line represents the thickest string (Low E). The top horizontal line represents the thinnest string (high E). 
  • The vertical lines represent the frets on the guitar (thin metal lines on your guitar fretboard)
  • The numbers inside the circles tell you what fingers to use to press down on your fretting hand (see the fingering chart in the following section)

Minor 7th b5 progression examples

Finally, let’s apply these chords in a progression. The half diminished chord is typically used as the “2 chord in a minor progression” or the “7 chord” in a Major progression. See the examples below to better understand this.

The audio examples are included under the notation. You’ll hear the regular tempo and a slower tempo to help you learn each example.

Chord progression 1

Progression 1 chords are B half diminished, E 7, and A minor 7. This is would labeled as a “2 5 1” in the key of A minor. This progression is one of the bread and butter progressions used jazz.

Chord progression 2

Progression 2 chords are Bb Major 7, A minor 7 b5, D 7, G minor, G minor/F#, G minor/F, and E minor 7 b5.

In this example, the A minor 7 b5 in measure 2 is the “7 chord” in the key of Bb Major or “2 chord” in G minor. The E minor 7 b5 chord in measure 4 finalizes a cliché chord movement starting on the G minor in measure 3.

Side note: G minor 6 and E minor 7 b5 share the same notes so they can be used interchangeably.

Chord progression 3

The chords in this last progression are C# minor 7 b5, C minor 7, B minor 7, E 7 (b9,13), A minor 7, F# minor 7 b5, and G Major 6 (9).

The F# minor 7 b5 in measure 3 acts as substitute for a D 7 (9) chord because it shares most of the notes.

This is a typical jazz chord progression ending. The function of the C# minor 7 b5 acts like a “2 chord” of the 3 chord in the key of G Major. We’re using a Bossa Nova rhythm to switch things up here.
