Triads with Doublings and Suspended 4ths (Harmonized Scale: “D” Harmonic Minor)

The following examples show various four-note triadic constructions with doublings and suspensions moved through a “D” Harmonic Minor scale.

The first chord is a commonly played triad with a duplicated root. The intervals, stacked vertically, are as follows: 5th, 4th, & 3rd. The intervallic construction is maintained and moved through the harmonized scale:

Next, the 3d is suspended (replaced with a diatonic fourth) and the resulting 5th, 4th & 4th construction is moved through the scale:

The second voicing type is a triad with a duplicated 3rd. The intervals, stacked vertically, are as follows: 3rd, 4th, & 3rd. The intervallic structure is maintained and moved through the harmonized scale:

Next, the upper 3d is suspended (replaced with a diatonic fourth) and the resulting 3rd, 4th & 4th construction is moved through the scale:

The third construction is a triad with a duplicated 5th. The intervals, stacked vertically, are as follows: 4th, 3rd, & 3rd. The intervallic structure is maintained and moved through the harmonized scale:

Next, the 3d is suspended (replaced with a diatonic fourth) and the resulting 4th, 4th & 2nd construction is moved through the scale:

Try finding additional four-note triads with duplicate notes or “doublings.” Here are two other possible starting chords:

Also, try transferring these voicings onto other string sets. Here is one of the previous chords transposed down an octave and placed on string set 5432:

Finally, experiment with various scales. Harmonic Minor is particularly useful, however, as it contains Major, Minor, Diminished, and Augmented triads.

6th & Diminished 7th Chord Passages: Bebop Major and Minor

These chord passages are constructed from inversions of 6th chords (Major and Minor respectively) with Fully Diminished 7th chords interspersed.

This is a harmonization technique that is often associated with the pianist Barry Harris.

Remember to analyze these from other roots, reinterpret the harmony and use your imagination to find less than obvious substitutions.
