What Gets Left Out, and Why
- 5th: The 5th adds little independent color once a 3rd (or minor 3rd) and a 7th already establish the chord’s quality, so it is usually the first tone dropped to keep an extended voicing playable under one hand.
- 9th: The 9th is a color tone rather than a defining one here — dropping it keeps the voicing compact while the remaining upper extension still carries the chord’s extended identity.
- 11th: The 11th is left out both because it is not essential to identifying the chord and because, against a major 3rd, a natural 11th sits a half step above it and can clash if voiced close together.
The tones that remain — root, minor 3rd, flat 7th, and 13th — the minor 3rd is what marks this as a minor extended chord — are exactly what make this chord recognizable, without the tones that mainly add density.
Playing This Voicing
One practical way to divide these notes between the hands: root (and 7th, if present) in the left hand, with the remaining color tones in the right. This is an example practical distribution, not the only correct way to play this voicing — how you split it depends on the song, the register, and what else is happening around it.
