Jazz pianists in the decades prior to the 1950s generally played more block chords and/or shell voicings (like roots and 7ths) and put the root in their voicings most of the time. These left-hand voicings were largely pioneered in the 1950s by jazz pianists such as Bill Evans.
However, MANY chords ARE listed, and this should be a great resource for jazz pianists looking to expand their vocabulary of left-hand voicings. This list does not contain more than two ways of playing any chord, and in many cases there is only one voicing listed for a particular chord. There are surely chords that are left out.
This isn’t an all-encompassing resource, as a resource that truly lists every possibility would be impossible. This PDF will be a BIG help to many jazz pianists and other instrumentalists who want to get better at voicing chords in their left hand! Many players could benefit from having this reference sheet, which has most of the chords jazz musicians are likely to encounter.
