Waldron's own assessment of his style was that it was partly a reflection of his personality: "It's part of my personality to be very economical with what I have and to use it in all variations before I move to the next set of notes". He acknowledged the influences of Holiday (on his conception of space and playing behind the beat), Mingus (for the importance of individuality), and Roach (on the value of time signatures other than the usual 4/4), as well as pianists Duke Ellington, Monk, Powell and Art Tatum.
