So if we follow the progression, the next logical step after 2-note and 3-note voicings is to progress to 4-note ii-V7-I voicings. I’m headed out the door soon so I don’t have much time to write but not much explanation is required. Just as with the 3-note voicings, the first document has Major ii-Vs with key centers descending by Major 2nds and the second document has Major ii-Vs with key centers moving by the circle of fourths. The voicings are built two ways – off the 3rd and off the 7th. And, again, even though they are rootless voicings, the root is in the bass clef for demonstration purposes and can be played with the left hand to help get accustomed to the sound of the chord. If you’re playing in a situation where there’s a bass player, you can drop out the root since it will already be covered. You’ll want to practice the voicings in the right hand and the left hand so you’ll have them at the ready for a variety of musical situations.
