I believe the first one to use the term 'tatum' was Bilmes, in his
master's thesis "Timing is of the essence: Perceptual and computational
techniques for representing, learning, and reproducing expressive timing
in percussive music" (MIT, 1993).
p.22, he writes:
"It is the lowest level of the metric musical hierarchy. We use it to
judge the placement of all musical events."
"Often, it is an illusory perception."
"Often, it is defined by the smallest time interval between successive
notes in a rhythmic phrase." This could be compared to a definition given
by Schloss, in his PhD Thesis (p33) refering to Yeston's "attack-point":
"Attack-point: distance (duration) between attacks, in term of the local
Bilmes also writes:
"Other times, however, the tatum is not as apparent; then, it might best
be described as that time division that most highly coincides with all
