Introduction
Rootless voicings are also known as left hand voicings or Bill Evans voicings so be aware that these three terms refer to the same thing. In this lesson we are going to cover what a voicing is, what makes it rootless and why we use rootless voicings.

We are then going to build rootless voicings for major, minor and dominant chords and then cover the best way to practise these voicings so that your are comfortable playing them on demand in all 12 keys.

What is a Voicing & What Makes it Rootless?
A voicing is the way that we choose to spread out or arrange the notes of a chord on the keyboard. We learn in the lesson on chord extensions that we can extend the chord past the octave to play the 9th, 11th and 13th .
To play a rootless voicing, we leave out the root of the chord and play one of the extensions instead so for example we could play the 3rd , 5th , 7th and 9th of the chord.

Why Do We Use Rootless Voicings?
Rootless voicings achieve very smooth voice leading in a 251 progression which has 2 main benefits:

The first is that the chords will flow from one to the next very smoothly which sounds great to the listener!

The second is that it reduces hand movement to a minimum so that you can move from one chord to the next very easily and focus you attention on soloing in your right hand.

Rootless voicings free up a finger for more interesting and colourful note choices such as a 9th, 11th or 13th which makes your playing sound more professional.

If you are playing in a jazz band, the bass player will have the root of the chord covered so there is no need for you to play it.

Rootless Voicings For Major Chords
To turn a major chord into a rootless voicing, we add the 9th and then drop the root. The alternative way to build a rootless voicing for major chords is to build a minor 7th chord off the major 3rd . In the key of C you would build a minor 7th chord of E which is the third.
Rootless Voicings For Minor Chords
We build minor rootless voicings in the same way as with major chords, we add the 9 and we drop the root. Remember that both major and minor chords share the same 9th. The alternative way to build a rootless voicing for minor chords is to go to the minor 3rd and build a major 7th chord. In the key of C minor we build a major 7th chord of Eb which is the minor 3rd.

Inverting Rootless Voicings
There are two important inversions that you need to learn for rootless voicings – Type A and Type B.

The formula for Type A rootless voicings is 3-5-7-9.

The formula for Type B rootless voicings is 7-9-3-5.

Type A rootless voicings always have the 3rd on the bottom and Type B always have the 7th on the bottom. An easy way to get from Type A to Type B is to take the bottom two notes and put them on the top (or take the top two notes and put them on the bottom).

Why Invert Rootless Voicings?
You might be wondering why we invert rootless voicings and the answer is so that we can play them in the correct register of the piano. Rootless voicings sound best when played right in the centre of the piano (around middle C). If you play rootless voicings too low on the keyboard they will sound ‘muddy’ and distorted. If you play them too high they will sound very ‘thin’.

By inverting rootless voicings you can always play them on or close to the centre of the piano to get the best sound.

Dominant Rootless Voicings
Rootless dominant 7th voicings are a bit trickier than major and minor chords. We could voice them in the same way that we have voiced the major and minor chords. However, this would not voice lead smoothly in the context of a 251 progression.

Instead we substitute the 5th for the 13th. This creates tension and dissonance between the 13th and then b7th .
