The characteristic that perhaps most distinguishes McKenna's playing is his sense of time. One of the biggest challenges of solo jazz piano is the need to provide a compelling time feel, in part by emulating the rhythmic landscape normally provided by three or four players in a small group. By conceiving multiple "parts" and playing them with distinct volume levels and time feels (often with right hand chords ahead of the beat and the melody behind the beat), McKenna had a unique ability to reproduce, on his own, the sound of a small group.
