For my next installment on basic jazz piano voicings I've decided to include a simple way of looking at using chords voiced in fourths. Everybody quickly recognizes this sound and some of the greats who started using this sound exclusively back in the '60s include Chick Corea and McCoy Tyner. However the sound goes as far back as Bud Powell, George Shearing, and Dave Brubeck. Examples from the former abound but examples from the latter provide an interesting evolution of the jazz piano sound from the shell voicings of the swing era to the more modern sounds in the post-bop era. One record in particular which spans this gap is Brubeck's first solo piano record "Brubeck Plays Brubeck". While not of the same caliber of sophistication as some of the other solo pianists of his generation this record offers an interesting first recording of some of Brubeck's famous tunes like "In Your Own Sweet Way" and "The Duke". At the same time it shows the development of jazz piano out of the bebop era into more modern territory. I've included a little exercise which if practiced in 12 keys will complement the sound of the shell voicings (See my early posts "Jazz piano voicings I-IV) Have fun.
