How to Not Suck at Half-Diminished Chords

Half diminished chords are generally overlooked. They are the neglected partner of a V7 chord in a minor two-five, that never gets the attention it deserves.

The result: we suck at them. Think about it. Are you as comfortable on Bb half diminished as Bb major? I’m guessing not. But there really is no reason you can’t be…

Common ways we get through them now

Part of the reason we do not perform as well over these type of chords as we would like is that we have adopted standard ways to get through them and have not moved past our tried and true methods. These techniques sound correct, were played by the masters, and are legitimate, the only problem being…they get boring.

This is what I call the  ‘harmonic minor scale trick.’ You simply play the harmonic minor of the minor tonic you are headed to over the minor two-five. Bird used this concept constantly and you probably do too.

Another common way people get by on half diminished chords is by arpeggiating the chord. Again, not a bad place to start, but at some point you’re going to want to move beyond this.

Half Diminished Arpeggio

Always knowing a few sure-fire ways of getting through a chord or set of chords is important, but it is just a starting point. The goal is freedom. If you are truly free over chords, then you are not limited by the number of phrases you know that ‘work’ over them. In other words, you have gathered a fair amount of workable knowledge that you can  implement, that allows you to freely create.

Determine where you’re at

Do a quick test in your mind to see where you are at. It may be surprising.

Pick a half diminshed chord that you feel fairly comfortable with. Now,think of yourself playing over that particular chord. Continue in this manner for about ten seconds…

Now move up a half step and repeat. Continue in this manner until you’ve gone through all twelve keys.

What did you notice? Were some easier than others? What was the transition like when I asked you to move up a half-step? Did you have to stop for a second and think about what you would play?

When i did this experiment, it dawned on me that there were four or five that I felt pretty comfortable on and the rest were a shot in the dark. Could it really be that over half of these chords I barely knew? Most standards tend to hang around certain keys and therefore, use the same few half diminished chords. What we end up with is seeing the same four over and over, while rarely encountering the other eight, making for a world of pain when we do.

Starting out

When you play the following exercises, do not learn them to reproduce them when you perform. Although they may come out at some point, their purpose is to increase you comfort level and familiarity with the sounds and fingerings over the chords, thereby giving you freedom on the chords to create your own original melodies. As you know, I’m a big fan of transcribing and I highly suggest you transcribe lines you like over half diminished chords. Use the exercises here to supplement your transcribed lines, not to replace them.

A great way to practice these exercises is to hammer down the chord on the piano and hold the sustain pedal, while you play through the exercise. Pay close attention to how the notes sound against the chord. Practicing in this manner overtime, you will hear the chord in your mind and how each note you are playing functions against that chord, making it unnecessary to have the chord sounded while you play the exercise.

Basic Warm Ups For Half Diminished Chords

Start by playing the Locrian mode up from root to root, and back down again. Train your ear to hear the notes in the context of the locrian scale. In other words, make sure to hear the tonic of the Locrian scale as the tonic, not the tonic of the parent major scale.

Now play the scale full range of your horn. Remember, this is just to warm up and get the feel for the scale. Only spend a minute or two refreshing yourself on these.

Next play 1234531. Take this pattern up chromatically through all the keys. This exercise will help you get familiar with the diminished triad (ie. B-D-F).

After you play the previous pattern for a while, follow it immediately by 5432135 in the same key. Then take the whole pattern through all the keys.

When I do these type of exercises, not only do I frequently accompany myself with the chord on the piano, but I also make sure to visualize the chord symbol while I’m playing through each key.

Getting to the Meat of the Chord

This exercise will help solidify the most important notes of the chord into your mind, ear, and fingers (The 3rd, 5th, and 7th). It will also help you get comfortable on half diminished chords, which really is the key to being able to improvise over any chords.

Play 3456753 followed by 7654357. This is easy if you think of the minor chord based on the starting pitch. So, for B half diminished, think D minor. First your brain will construct shortcuts like this little minor-trick, but after a while the notes will translate to the chord you are working on and you won’t need the shortcut anymore.

Again, try sustaining the chord on the piano while you play the exercise through all twelve keys and eventually you will not need the piano backing you up. The chords will naturally begin to function in your ear, allowing you to hear and create your own original melodies.

Transitioning to the altered dominant chord

This exercise will help your ear learn to connect half diminished chords to the chord that typically follows them: the V7alt. chord.

Play 34567537 on the half diminished chord, to 37 on the  V7 chord. Continue in this manner, resolving each dominant chord. This will get you through half of the keys, make sure you do the other half.

Not Sucking at Half Diminished Chords

Learning not suck at these chords takes time. Practice these exercises diligently for twenty minutes a day and within just a couple weeks you will find yourself feeling comfortable in all keys on half diminished chords. Remember, these are exercises to assist in your ability to hear how these chords sound in context, while laying the ground work for your fingers to know where these sounds lay on your instrument. They are not meant to be reproduced verbatim in your solos. Go slowly and let each sound ring in your ear as long as it takes to get it to permeate into your musical mind.

Where to go from here:

  • Make up your own exercises similar to these using various combinations of chord tones and scale pieces and remember their purpose.
  • Often the flat 9th on a half diminished chord is treated as passing tone due to it’s dissonant quality. Try using the natural 9 (C# on B half-dim) instead of the flat nine and see if you can integrate it in a musical way
  • Try playing other chord tones on the altered dominant, perhaps the b5, b13, b9, or #9
  • Work on tunes that emphasize half diminished chords such as: Stella by Starlight, Woody’n You, or Inner Urge
  • Understand how to play half diminshed chords in different contexts, for instance, in “Woody’n You” the half diminished chords are a part of a minor ii-V, whereas in “Inner Urge” the half diminished chords are on their own for an extended period of time. You may find that you need to approach these situations differently.
  • Transcribe some lines of your favorite players playing over half diminished chords

These chords are kind of a bitch, so stay tuned and there will be plenty more about how to not suck at half diminished chords in the future.
