Let’s take a look at a few things that can be done when an altered dominant chord presents itself in a tune (e.g. Eb7alt). The first thing to know is that the altered chord derives from the altered mode, otherwise known as mode VII of melodic minor. But to break out of the diatonic sound of the scale and gain a little freedom with it, here are a few tricks…
There are 5 different triads that can be used as numerators (the denominator being the basic chord sound, i.e. combinations of chord tones 1, 3, and b7) to get a solid sounding upper structure triad voicing for an altered chord:
You can then combine both minor triadic upper structures and both major triadic upper structures to form two hexatonic scales, which can be used as interesting melodic devices:
Now, if you take a closer look at both these hexatonics, you’ll notice that they have five notes in common. These notes make up a pentatonic scale (bV major pentatonic, a.k.a. bIII minor pentatonic), which can also be used as an even more angular melodic device.

The following “meditative practicing” technique comes in really handy when far away from your instrument.
All you have to do is choose a notated piece of music that you’ve got memorized and try and play it in your mind as precisely as possible, hearing it, and even feeling the touch of the piano (this also works if you play another instrument: just mentally recall the feeling you experience when playing your particular instrument). For pianists, Bach’s Inventions work well because they consist of two contrapuntal parts, which are already challenging enough to hear simultaneously with the mind’s ear. But you can choose virtually any piece of music. When a passage seems unclear, go back and “replay” it again, slower if necessary (just as you would when you practice on your instrument) until you’re able to hear each note, as well as each item of expression attached to each note, with utmost precision.
This technique certainly requires sharp concentration and thus works best in a calm environment. But if practiced correctly, its benefits are certainly to be felt as soon as you return to the piano (the following day for example – it’s always good to allow the mental exercise to fully sink in during the night…): overall, your knowledge of the piece will have been considerably strengthened; your memory won’t fail you and you’ll be able to concentrate on musicality right off the bat.
I’ve recently been working on most of Johann Sebastian Bach’s Two-Part Inventions as a kind of warm-up for the fingers and the ears (I learn them by heart and usually go through several first thing in the morning or at the beginning of each of my piano practice sessions). As I was playing No. 3 (D major) today, I realized I mostly was using legato phrasing and decided to venture into a staccato rendition of the piece. With the change of expression (staccato versus the former legato phrasing), I found myself much less self-assured: my memory failed me and I had to refer to the music on a couple of occasions. This, to me, was an indicator that I wasn’t hearing the melodic lines as clearly as I thought I was able to. Indeed, I don’t think my memory would have been caught off guard in that manner if a had been hearing them strong. So in addition to being a useful technical exercise, practicing cantabile style playing using both legato and staccato phrasing seems to be yet another great way to strengthen one’s inner hearing, and thus a very musical exercise. Highly recommended!
To improve rhythmic independence? Of course. But also:
- it might lead you to use different voicings than the ones you usually use for comping. Sometimes a voicing might be too low and sound muddy when played with the left hand in the lower part of the keyboard, but the same voicing played higher up will sound OK due to the absence of low interval limit restrictions;
- the left hand is generally weaker and slower than the right hand. Such technical restriction forces you to rely more on musicality, inner hearing and singing when improvising with the left hand. When you then go back to improvising with the right hand, it feels a lot easier! Musicality is now right at your fingertips, with the greater technical ability of your strong hand available to serve it.
